    All new homes should be EV-ready, says international code council – The Driven - January 17, 2020 by admin

    The leading international organisation for building codes and standards says that all newly constructed homes should be EV-ready, and guidelines have been recently accepted by US local governments to ensure electric vehicles (EVs) are taken into account for all new building constructions.

    A global transition to electric mobility is already well underway: EV pioneer Tesla is now worth more than General Motors and Ford combined at around $US90 billion ($130 billion), legacy car-makers such as Volkswagen, Hyundai, Ford, and most recently Kia have announced billions invested towards developing electric models, and others such as GM, BMW, Daimler have promised electric models in coming years.

    In a release on the new guidelines for improving the energy efficiency of US homes from the New Buildings Institute last Monday, the body noted the important role that electric vehicles have to play in tackling climate change.

    Electrification of buildings and vehicleswith clean, renewable power supplyis one of the key policy solutions for tackling climate change, and in new buildings electrification readiness can be done at a very small incremental cost, the institute noted.

    The new guidelines will require all new buildings to make a percentage of parking spaces ready and available for electric vehicles, including installation of the necessary electric infrastructure to avoid expensive retro-fitting later on.

    In Australia, the need for new buildings to be EV-ready was recognised in the proposed EV policy plan by the Australian Labor party in the lead up to 2019s May election.

    However, a vicious and blatantly incorrect campaign run by the Morrison LNP government, and particularly minister for energy Angus Taylor, included claims that the policy amounted to a housing tax that would cost consumers thousands of dollars.

    The new building guidelines outlined by the ICC are designed to avoid unnecessary costs rather than add to them.

    The code change proposal will increase the cost of initial construction, but provide long-term savings for EV owners through the avoided retrofit costs of installing EV charging infrastructure, it is noted in the new definitions added by the ICC to the 2018 Energy Conservation Code.

    Publicly accessible electric vehicle DC fast charging infrastructure that is typically accessed on highways and other key routes now has considerable penetration the US, but access to adequate AC charging at home so EV owners can charge EVs in much the same way as mobile phones is also a critical piece of the puzzle.

    As noted by the ICC, the lack of access to EV charging stations continues to be a critical barrier to EV adoption. In particular, there are significant logistical barriers for residents of multi-family dwellings to upgrade existing electrical infrastructure and install new EV charging stations.

    A lack of pre-existing EV charging infrastructure, such as electrical panel capacity, raceways, and pre-wiring, can make the installation of a new charging station cost-prohibitive for a potential EV-owner.

    The installation of an EV charging station is made three to four times less expensive when the infrastructure is installed during the initial construction phase as opposed to retrofitting existing buildings to accommodate the new electrical equipment.

    New residential buildings are constructed to last for decades, and so it is critical that EV charging infrastructure is incorporated at the pre-construction stage to ensure that new buildings can accommodate the charging needs of future EV-owners, it concludes.

    New definitions added by the ICC include:

    ELECTRIC VEHICLE SUPPLY EQUIPMENT (EVSE): The conductors, including the ungrounded, grounded, and equipment grounding conductors, and the Electric Vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatus installed specifically for the purpose of transferring energy between the premises wiring and the Electric Vehicle.

    EV CAPABLE SPACE: Electrical panel capacity and space to support a minimum 40-ampere, 208/240-volt branch circuit for each EV parking space, and the installation of raceways, both underground and surface mounted, to support the EVSE.

    EV READY SPACE: A designated parking space which is provided with one 40-ampere, 208/240-volt dedicated branch circuit for EVSE servicing Electric Vehicles. The circuit shall terminate in a suitable termination point such as a receptacle, junction box, or an EVSE, and be located in close proximity to the proposed location of the EV parking spaces.

    General Requirements of the NEC – EC&M - January 17, 2020 by admin

    Article 110 of the National Electrical Code (NEC) covers the general requirements for the examination and approval, installation and use, access to, and spaces about electrical equipment. Some of the quick requirements include:

    Be careful not to confuse the term interrupting rating [Sec. 110.9] with short-circuit current rating [Sec. 110.10].

    Overcurrent protective devices must have an interrupting rating capacity equal to or greater than the fault current available at the equipment line terminals [Sec. 110.9]. Unless marked otherwise, the ampere interrupting capacity (AIC)rating for circuit breakers is 5,000A [Sec. 240.83(C)], and it is 10,000A for fuses [Sec. 240.60(C)(3)].

    Electrical equipment must have a short-circuit current rating (SCCR) that permits the circuit protective device to open due to a short circuit or ground fault without extensive damage to the electrical equipment [Sec. 110.10]. Listed equipment applied per its listing meets this requirement (Fig. 1).

    Fig. 1. Electrical equipment must have a short-circuit current rating (SCCR) that permits the circuit protective device to open due to a short circuit or ground fault without extensive damage to the electrical equipment.

    Available shortcircuit current is the current, in amperes, available at a given point in the electrical system. This current is first determined at the secondary terminals of the serving electric utility transformer. Thereafter, the available shortcircuit current is calculated at the terminals of the service disconnect, then panelboards and other equipment as various connections are made downstream from the main service. Beginning at the serving electric utility transformer, the available shortcircuit current decreases at each downstream connection point of the electrical system.

    Electrical equipment and cabling must be installed in a neat and workmanlike manner [Sec. 110.12]. One aspect of this is that unused openings must be closed by fittings that provide protection substantially equivalent to the wall of the equipment [Sec. 110.12(A) and (C)].

    Exposed cables must be supported by the structural components of the building so that the cable will not be damaged by normal building use. Electrical equipment must be firmly secured to the surface on which it is mounted [Sec. 110.13].

    Conductor terminal and splicing devices must be identified for the conductor material, and they must be properly installed and used per the manufacturers instructions [Sec. 110.3(B)].

    Single direct burial types UF or USE conductors can be spliced underground with a device that is listed for direct burial [Sec. 300.5(E) and Sec. 300.15(G)]. Multiconductor UF or USE cables can have the individual conductors spliced underground with a listed splice kit that encapsulates the conductors and cable jacket.

    Electrical connection failures cause insulation failure, short circuits, ground faults, and fires. Improper terminations, poor workmanship, violating the manufacturers instructions, and improper torqueing can each cause poor electrical connections.

    For equipment rated 100A or less, size conductors 1 AWG and smaller per the ampacities in the 60C temperature column of Table 310.16 [Sec. 110.14(C)(1)(a)(1)]. Conductors rated for at least 75C temperature and that terminate on terminals rated 75C can be sized per the ampacities in the 75C temperature column of Table 310.16 [Sec. 110.14(C)(1)(a)(3)].

    For equipment rated greater than 100A, size the conductor per the ampacities in the 75C temperature column of Table 310.16 [Sec. 110.14(C)(1)(b)(1)] (Fig. 2). Splicing and terminating devices with terminals rated 90C and not connected to electrical equipment can have their conductors sized per the ampacities in the 90C temperature column of Table 310.16 [Sec. 110.14(C)(2)].

    Fig. 2. For equipment rated over 100A, size the conductor per the ampacities in the 75C temperature column of Table 310.16.

    Markings

    Youll find many requirements for markings throughout Art. 110. For example, where caution, warning, or danger labels are required, the labels must meet three requirements [Sec. 110.21(B)]:

    1. The markings must warn of the hazards using effective words, colors, symbols, or a combination of words, colors, and symbols.

    2. The label cannot be handwritten, and it must be permanently affixed to the equipment.

    3. The marking must be of sufficient durability to withstand the environment involved.

    Some other marking requirements include:

    Spaces about electrical equipment consist of working space for worker protection [Sec. 110.26(A)] and dedicated space to provide access to, and protection of, equipment [Sec. 110.26(E)]. The working space must always be clear; therefore, this space cannot be used for storage [Sec. 110.26(B)]. Working space is not required at the back or sides of equipment where all connections and all renewable, adjustable, or serviceable parts are accessible from the front of the equipment.

    While OSHA and NEC tables provide values for various voltages and conditions, these are minimum values. The actual values needed for adequate working space and worker protection in each installation may be greater. NFPA 70E, Standard for Electrical Safety in the Workplace, provides guidance in determining the severity of potential exposure, planning safe work practices including establishing an electrically safe work condition arc flash labeling, and selecting personal protective equipment (PPE).

    The point of determining the correct working space for a given installation isnt to see how little of it you can get by with. The point is to determine how much is needed to efficiently and safely service the equipment. The efficiency aspect isnt required by OSHA or the NEC, but it can dramatically affect operational profitability. This same logic applies to Part III of Art. 110, which provides working space requirements for installations over 1,000V.

    You must allow for sufficient depth, width, and height:

    Exception No. 1: The minimum height of working space does not apply to a service disconnect or panelboards rated 200A or less located in an existing dwelling unit.

    Fig. 3. The height of the working space must be clear and extend from the grade, floor, or platform to a height of 6 ft or the height of the equipment.

    Exception No. 2: Meters are permitted in the working space.

    If equipment thats above a suspended ceiling or in a crawl space is likely to require servicing while energized, all of these conditions apply [Sec. 110.26(A)(4)]:

    (1) Equipment above a suspended ceiling must have an access opening at least 22 in. 22 in. Equipment in a crawl space must have an accessible opening at least 22 in. 30 in.

    (2) The working space width must be at least 30 in., but never less than the width of the equipment.

    (3) The working space must permit equipment doors to open 90.

    (4) The working space in front of the equipment must comply with the depth requirements of Table 110.26(A)(1); horizontal ceiling structural members are permitted in this space.

    When live parts are exposed for inspection or servicing, the working space, if in a passageway or open space, must be suitably guarded. Furthermore, at least one entrance must provide access to and egress from the working space. [Sec. 110.26(C)].

    Thinking that you can just look up something from here if a question arises is a mistake. To avoid errors, allot time on a regular basis to study, understand, and be familiar with the requirements.

    Working space issues are especially an area of confusion. Remember, nothing prevents you from exceeding working space minimums if conditions merit doing so. You just cant go the other direction.

    General Requirements of the NEC - EC&M

    All new-built homes in the US will be EV ready – Red, Green, and Blue - January 17, 2020 by admin

    The US will need9.6 millionnew electric vehicle charging ports by 2030. Where will all those chargers be located? According torecent research, almost 80% of those will be in single and multi-family residential buildings. Thats a big change. Homes in the US are typically built with wiring for only a few 240W outlets in the garage, just enough to handle a washer and dryer. But theInternational Code Council(ICC) has foreseen the need for this radical increase in EV chargers, and it approved changes to building standards in a2020 provisionthat will allow all new homes built in the US to be EV-ready.

    By Carolyn FortunaCleantechnica

    In 2019, there were more than 68,800 Level 2 and DC fast charging units throughout the United States. Of that total, 16%, or approximately 10,860 units, were DC fast chargers that make long-distance travel more practical for electric vehicles (EV), according to theOffice of Energy Efficiency and Renewable Energy.

    TheSouthwest Energy Efficiency Projectarguesthat EV-ready building codes are one of the most effective and low-cost strategies for states and local governments to encourage consumers to buy or lease electric vehicles. At their most basic, they say, the codes establish EV infrastructure requirements for new construction projects, including the electrical capacity and pre-wiring to make possible the future installation of EV charging stations. States and municipalities around the country have developed their own EV-ready building codes to accommodate local EV market trends and to meet community-specific climate goals.

    The new ICC guidelines call for installing panels, outlets, and conduits capable of charging at least one full-size EV in a single-family garage overnight. Multi-family buildings will need two spots, along with more that can be easily retrofitted, a standard known as EV capable. Homeowners will still need to install their own EV charging equipment.

    Heres the actualICC languageof the new EV-ready standard:

    R404.2 (IRC N1104.2) Electric Vehicle (EV) charging for new construction. New construction shall facilitate future installation and use of Electric Vehicle Supply Equipment (EVSE) in accordance with the National Electrical Code (NFPA 70).

    R404.2.1 (IRC N1104.2.1) One- to two-family dwellings and townhouses. For each dwelling unit, provide at least one EV Ready Space. The branch circuit shall be identified as EV Ready in the service panel or subpanel directory, and the termination location shall be marked as EV Ready. Exception: EV Ready Spaces are not required where no parking spaces are provided.

    tR404.2.2 (IRC N1104.2.2) Multifamily dwellings (three or more units). EV Ready Spaces and EV Capable Spaces shall be provided in accordance with Table R404.2.2. Where the calculation of percent served results in a fractional parking space, it shall round up to the next whole number. The service panel or subpanel circuit directory shall identify the spaces reserved to support EV charging as EV Capable or EV Ready. The raceway location shall be permanently and visibly marked as EV Capable.

    The definitions for the ICC EV-ready construction are as follows:

    ELECTRIC VEHICLE SUPPLY EQUIPMENT (EVSE). The conductors, including the ungrounded, grounded, and equipment grounding conductors, and the Electric Vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatus installed specifically for the purpose of transferring energy between the premises wiring and the Electric Vehicle.

    EV CAPABLE SPACE. Electrical panel capacity and space to support a minimum 40-ampere, 208/240-volt branch circuit for each EV parking space, and the installation of raceways, both underground and surface mounted, to support the EVSE.

    EV READY SPACE. A designated parking space which is provided with one 40-ampere, 208/240-volt dedicated branch circuit for EVSE servicing Electric Vehicles. The circuit shall terminate in a suitable termination point such as a receptacle, junction box, or an EVSE, and be located in close proximity to the proposed location of the EV parking spaces.

    A2016 studydetermined that installing PEV charging infrastructure during initial construction is very cost effective. The cost for installing complete or nearly complete 240-volt 40-amp electric circuits as a retrofit is several times more expensive than installing this infrastructure during new construction. The study authors concluded that installing infrastructure during new construction can avoid retrofit costs including breaking and repairing walls, longer raceways (also referred to as conduit) using more expensive methods and upgrading electric service panels. In addition, the soft costs such as permitting and inspections and project management are much lower for new construction.

    The ICC is the building standards organization which sets voluntary guidelines for new homes. The ICC, a non-profit trade association, develops model codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. It has 64,00 members with 377 chapters worldwide.

    There’s a petition calling for a ‘War on Drugs’ medal. Here are 11 other awards also worth considering – Task & Purpose - January 17, 2020 by admin

    Should service members be issued a "War on Drugs" medal recognizing the role the U.S. military has played in combating global drug trafficking over past five decades? One petitioner believes they should.

    The petition calls for the president of the United States, in this case, Donald Trump, to issue an executive order that establishes the "War on Drugs Service Medal" as a "total force" military award that recognizes all service members from 1971 to the present. The White House petition was created by Thomas Marriott, who dedicated the effort to his father, Lt. Col. John Thomas Marriott II, according to the campaign's website.

    When asked how such an award would, or could be created, the Pentagon directed Task & Purpose to Volumes 1-4 of Department of Defense Manual 1348.33, writing that those hundred-plus pages have "the language."

    However, the public affairs office did note that "most are established by Law and/or Executive Order," and that this specific petition "has not been discussed at the Pentagon."

    So, that's something.

    Marriott's petition, and the accompanying website, appear earnest, and the military has certainly played a significant role in taking on drug traffickers across the globe, from providing training and support to allied militaries, to drug interdiction operations like that time a Coastie showed off his brass balls by leaping atop a speeding narco-submarine in the middle of the ocean.

    However, as much as we here at Task & Purpose love the idea of getting a new piece of chest candy, we're also growing a little tired of endless wars.

    In light of that, we came up with a list of 11 other awards we'd like the Pentagon to consider making official, beginning with...

    Operation Enduring Clusterfuck Campaign Medal: For all those who served in Iraq and Afghanistan in the early days who are now realizing that this shit is never going to actually end.

    Belligerence In Uniform Award: Awarded to E-4s and below who spent four years or more getting chewed out for having 3+ inches of hair on their heads.

    Valorous Hands-In-Pockets Medal: Given to those who in the face of overwhelming odds refused to remove their hands from their pockets while getting knife-handed by a squad-sized element of staff non-commissioned officers.

    Twentynine Palms/Fort Irwin Service Ribbon: In recognition of the selfless sacrifice made by those poor souls who endured a non-deployable duty assignment to Marine Corps Air Ground Combat Center Twentynine Palms, or Fort Irwin National Training Center, in California.

    Intergalactic Defense Ribbon: Awarded to the first enlistees of the Space Force.

    Knife Hand Action Badge: Awarded to non-commissioned officers who perfected the knife-hand when counseling junior soldiers.

    Meritorious Barracks Legal Ribbon: Awarded to junior soldiers who display prominent legal knowledge without having any type of law degree.

    Terminal Lance Corporal Achievement Award: Awarded to enlisted Marines upon second promotion to Lance Corporal following a loss of rank due to non-judicial punishment. Gold Oak Leaf clusters denote additional awards.

    The Content Wars Award: Awarded to any and all former U.S. service members who record at least 10 video rants in the driver's seat of their truck within the first month of separation. Recipients are eligible for 'V' devices if the truck is moving.

    National Military Base Housing Ribbon: Awarded to service members (and their families) who endured and survived asbestos, mold and faulty wiring while living on any military installation.

    E-4 Mafia Unit Citation: Awarded to members of an Army battalion where 90% of specialists are absent from mandatory morning PT, working parties, and are a constant presence in the smoke pit.

    Emporia Vue energy monitor review: Understand your home’s energy consumption without breaking the bank – TechHive - January 17, 2020 by admin

    Want to know how much energy your home is using? You can take the power companys word for it, or you can measure your usage yourself. With a device like the Emporia Vue you can do this fairly simply and without having to complete any major rewiring.

    Like the Sense Energy Monitor we reviewed in early 2019, the Emporia Vue uses a pair of electromagnetic current sensors that clip on top of the two electrical mains that enter your circuit breaker. The sensors can detect the total amount of wattage your home is pulling down from the grid, and this information is fed once per second to an attached monitor.

    The monitor, via Wi-Fi, relays that information to Emporias servers in the cloud, and from there to an app on your smart phone. This enables you to observe your homes energy consumption in real time and historically.

    What Sense offers that Emporia does not is a way, via machine learning, to identify the footprint of different devices based on the way the devices in your home use power. Over time, Sense can identify your refrigerator, oven, furnace, and more. Add the Vue Expansion Module, and you can add up to eight additional clips that connect to individual circuits in your house and monitor them directly, without any guesswork.

    Emporias system, however, costs much less than Senses: The Emporia Vue base unit is just $50, plus another $60 if you choose to add the eight circuit-specific sensors (you can buy the two bundled for $100). A 200-amp, three-phase current sensor for light commercial implementations is also available for $15. Thats a significant savings any way you look at it; but, of course, you will face some caveats along the way.

    Cramming all of the Emporia Vues components into your electrical panels box can be challenging.

    First, installation isnt entirely a matter of just clipping sensors onto wiring. The Vue itself must be powered in order to work. That means shutting down your entire electrical system (the controls for which I discovered were in a completely different location outside my home) and connecting wires to an unused circuit breaker and to the neutral bus bar. If you dont have an unused breaker, a wire-tap pigtail is included in the box that lets you borrow a little power from a breaker thats otherwise in use.

    Connecting all of this isnt too much trouble, even if (like me) youve never done any work inside your electrical panel. Emporias instructions are easy to follow, and the only hiccup I encountered involved the antenna for the Vues Wi-Fi connection. Because electrical panels are metal and (of course) full of electrical gear, Wi-Fi signals dont penetrate far beyond the box. The antenna must be run outside the box by snaking the cable through a knockout and mounting it on the outside of the panel.

    This spike in the kitchen circuits consumption of electricity can be attributed to the coffee maker.

    My problem: My circuit breaker is recessed into the wall, which meant having to run the wire not just through a knockout but through the drywall, as well. For the purposes of my testing, I opted not to drill holes in the wall and instead just used the Vue with the cover of the breaker box removed during my testing.

    The other hardware issue with the Vue is that all these sensors and wires really add up quickly, and they consume a huge amount of space inside the breaker box. Just fitting the base Vue unit, along with two sensors, power adapter, and related wireless gear, inside the box can be difficult. My breaker box, with some 40 circuits connected and virtually nothing unused, is incredibly full of wiring, and finding a place to stash the Vue wasnt easy. This was compounded when I added the expansion module and its additional sensors, which arent the smallest. I managed to find room for four of the eight inside the box before my panel started to look like a plate of spaghettiand it became to reattach the panel cover. (Emporia sells alternate styles of clips, but we didnt receive these for review.)

    Once you have the Vue equipment and its mobile app installed, the system starts collecting data immediately. The primary Vue system works exactly as advertised, and I was able to watch my power consumption climb from 500 watts at night to nearly 2,000 watts in prime time. You can break down usage by anywhere from the second to the year, but the most useful views are the daily and hourly consumption views, which give you a more comprehensive and actionable understanding of your power draw.

    Emporias expansion module lets you monitor the energy consumption on specific circuits.

    If youve set up individual circuits to be monitored, the Vue system lets you drill down into each of them via the same interface. While its nice to monitor, say, the usage of the coffee maker or the entertainment center, I wasnt really drawn to checking these things more than once or twice, because their patterns didnt really change.

    If there was a way to stack all this information together and view it one screenso I could more easily see how much the air conditioner drew as a portion of the total power consumption, for examplethis might have been more useful. Also worth noting: the sensor for my dishwashers circuit never recorded any data, for reasons I was never able to determine.

    The Vue has no connections to other smart home systems or IFTTT, the latter of which could be useful to, say, alert you if power consumption climbs higher than expected or spikes when it shouldnt. Then again, Vue could infuse features like this directly into its app over time, which would only enhance its overall utility.

    ARPA is Leading the Transition Towards Sustainability – Army Technology - January 17, 2020 by admin

    The Spanish company ARPA launched a new business line, ARPA CHANGE, proposing the efficient and sustainable solutions that will change the industry. Doing this, ARPA pretends to help the private sector as well as the defence sector, in the transition to sustainability, showing that the change is possible. ARPA, the Spanish company with more than 50 years of experience in the design, manufacture and deployment of field logistic solutions, has a mission which is to lead the change to a world increasingly sustainable. To do so, ARPA has developed solutions based on solar energy, water treatment and waste management, which facilitate the accomplishment of the United Nations Sustainable Development Goals (SDGs) to meet the 2030 Agenda.

    We want to give a fair and adequate answer to the challenges of globalisation, designing, manufacturing and implementing turn-key sustainable solutions so all kind of installations, industries, hospitals, farms, hotels, sports centres, schools, residencies, barracks and business in general can adopt these technologies, leading the transition towards sustainability. Says Clara Arpa, CEO of the company.

    An example of an innovative solution is the production of energy by hybrid panels installations for power generation and hot water (with the most efficient panels in the market). The installation incorporates photovoltaic panels, which incorporate 60 or 72 photovoltaic cells, depending on the size of the panel, which are placed on a system for absorbing heat forming a single module. In addition to the common wiring for any panel, this system has a zone which is outputted to the heat will be used to heat water.

    A hydraulic circuit and a small tank thermally insulated complete the design that can provide this dual-use, without compromising the ability to produce electricity, since the photovoltaic cells of this panel 21 operate with improved performance, achieving improvements to 15% of the performance of photovoltaic panels. Besides the obvious advantage of having the space required to give the captured energy from the sun for both uses, production costs are reduced and installation, making it the most efficient hybrid solar panel in the market today, says Fernando Peitivi, Director of the renewable energy installations.

    With this solution, coupled with that also innovative water sanitation systems and waste management developed by the company, ARPA CHANGE aims to contribute to the implementation of Agenda 2030 through the goal number 8, decent economic growth and work. Contributing in improving their production processes so that companies reduce their emissions (if possible, to 0), better management of the water, reduce the generation of waste and having a positive impact on the environment.

    our goal is to encourage other companies to do so through a sustainability analysis, make a diagnosis of the sustainability and customise a solution for each installation, explains Clara Arpa. These installations can be made in many infrastructures, whether civil or military. An example would be the installation of such panels in barracks. Usually, in these cases the return on the investment is between 4 and 6 years and can obtain energy savings between 60 and 70%, leaving 530Kg issuing CO2 per panel.

    ARPA also features a hybrid monitor that collects and processes all the information from the solar installation (thermal, photovoltaic or hybrid), which can be accessed by the user in real-time as well as a history of thermal energy and/or electricity produced by the facility during the day, during the month or event from the first day you can find data such as cost savings, the amount of CO2 emissions that are no longer issued and the amount of energy produced by the installation site. With this strategic decision, ARPA confirms its indolent with sustainability and positions the private sector as a key element of change.

    By launching ARPA CHANGE, extrapolates its extensive experience in the activity of the company, which so far focused on the design, manufacture, installation, maintenance and management of mobile field equipment for military, civilian, health and all kind of emergencies all around the world. We want to show that sustainability can and should go in parallel with profitability and efficiency. We intend to contribute to a fairer world and this is our bit, concludes Clara Arpa.

    Arlo Video Doorbell review: Nest and Ring should be worried about this nicely equipped, solid value – Android Police - January 17, 2020 by admin

    How are you going to call yourself a smart-home company, one with a huge focus on video, and not have a video doorbell? That's a question Arlo had no doubt been asking itself for some time, and while it launched its Audio Doorbell with matching wireless Chime back in 2018, that one was largely meant to be used with the company's existing video cameras. It took another year for the follow-up effort to arrive, but in late 2019 we finally got a proper Arlo Video Doorbell.

    How will this new entry compare against Arlo's existing lineup of impressive cameras? What about video doorbells from other smart-home manufacturers? And is this going to be an easy upgrade for you, or should you think about calling an electrician? Let's get right into what the Arlo Video Doorbell has to offer:

    The design of the Arlo Video Doorbell should be pretty familiar to anyone with even a passing interest in smart doorbells if youve seen a Nest Hello, the Video Doorbell is going to look like its spitting image. That means a wide-angle camera up top, and a big illuminated button below just like with Arlos Audio Doorbell, that button lights up when the unit detects motion to clue users in as to where to press.

    The wide-angle camera sees a lot but misses packages directly underneath.

    Unlike some other Arlo hardware, the Video Doorbell works all by itself, so theres no hub included here, nor do you need to pick one up on your own.

    The Doorbell comes with plenty of mounting hardware, including a bracket you screw into the wall where your old doorbell went, an adapter for mounting at an angle (in case your doorbell isnt directly adjacent to your door), screws, optional anchors, and wire extensions in case they're needed.

    The other main piece of kit here is a power adapter that connects to your doorbells chime wiring. In contrast with the Arlo Audio Doorbell, which had a full-wireless option, the Video Doorbell requires connection to a wired doorbell system for power.

    The Video Doorbell illuminates its button in response to sensing motion.

    While the requirement to attach the Arlo Video Doorbell to a wired system makes setup quite complicated if youre starting from scratch and in which case, this goes from an easy DIY project to one that might benefit from a professional's touch upgrading an existing wired doorbell is easy-peasy.

    Assuming your existing doorbell wiring's in good shape, upgrading to the Arlo Video Doorbell is pretty straightforward mount the bracket and wire it up.

    After cutting the power and removing your old button you screw the new Arlo bracket to the door frame, attach the exposed wires, and click the Doorbell body in place if and when you need to remove it, an included SIM-tool-like pin sticks in the bottom to disengage. Next you've got to install the tiny power adapter near where your doorbell chimes lives. Exactly how youll attach that depends on your current installation, but Arlos setup guide helps talk you through your options.

    Left: Detaching the Doorbell with Arlo's impression of a SIM tool; Right: The optional angle bracket for mounting away from your door.

    Now, full disclosure: I hit a pretty big snag, in that while my house clearly had a wired doorbell at some point, and I can see the existing wires teasing me, I wasnt able to trace those anywhere nor find a transformer or chime. Luckily I managed to rig up a new transformer (which cost about $15-20) but elected to not bother with a chime. The Doorbell works just fine even without one, but doing this youll only get alerts on your phone when someone rings, and wont hear any ding-dong in the house. I would love it if you could link this model to Arlo's own Chime, but that will only function alongside the Audio Doorbell a curious if not unexpected limitation.

    This little power adapter easily connects to your doorbell's existing chime.

    In any case, once everythings wired up, restore power to your transformer and the Video Doorbell will be good to go. Setup with the app is nice and clean give your Doorbell a name, scan a QR code from your phone, and youre basically there.

    The most interesting thing about the Video Doorbells operation is its unusual camera sensor. A widescreen camera doesnt make a ton of sense with doorbell usage, so instead Arlo pairs a wide-angle lens with a square 1:1 sensor in 1538 x 1538 resolution. This offers a nice field of view, and while the resolution doesnt go quite as high as other Arlo devices, it feels pretty sufficient for what the Doorbell does.

    One slightly misleading detail is that Arlo advertises this as a 180-degree camera with the caveat that its 180 degrees when measured across the diagonal. This means that the cameras not going to see straight down, potentially missing packages right in front of your door. Testing my setup, I found that the camera's blind spot extends out about two feet from directly underneath.

    The Video Doorbell comes with three months of Arlo Smart service, which in addition to recording camera clips to the cloud, identifies people, vehicles, animals, and packages. To my great disappointment, though, the Doorbells functionality is drastically reduced for users who choose not to maintain a subscription since theres no connection to an Arlo hub for USB storage and no local microSD slot, it cant record video at all, so all you get are motion alerts and the opportunity to watch the camera's live feed.

    Where Arlo's camera can't see.

    Another limitation is that unlike some of those other doorbells, Arlo's seems unwilling to share its feed through Google Home. While you can see the linked Video Doorbell among your Arlo devices in Home, and streaming regular Arlo wireless cams works fine, the Video Doorbell does not appear to share that same support.

    Arlo users will see the Video Doorbell appear right alongside their existing cameras in the Arlo app's device listings or if you're starting fresh, all by its lonesome. From there you can view a live feed or adjust the product's settings those include assigning zones for motion activation, configuring HDR and night-vision options, and tweaking the Doorbell's audio (which is a little loud out-of-the-box).

    With Arlo Smart, you'll also have access to your full library of cloud recordings, including notes about the video subject as detected by Arlo's AI processing.

    Left: A visitor rings; Center: Accepting a call; Right: Delivering a canned response.

    When someone comes to your door and rings, you'll see it on your phone just like an incoming call. While this happens quite quickly, it's a little frustrating that you won't get any video (or even a still frame) until after you pick up. At that point you can talk to your guest through the Video Doorbell's speakerphone, deliver a canned response like "just leave the package" or "scram" (but a little nicer), or just ignore them it's your prerogative whether you choose to engage at all. If you decline to answer, visitors can be prompted with the option to record a message for you. And if everything just goes to hell, you can trigger an ear-piercing siren that should send anyone running.

    Ding-dong, Android Police calling!

    Arlo Video Doorbell

    8.5/10

    Of course, there are also long-term costs to consider, and you're basically stuck with needing Arlo Smart at a minimum of $3 a month or $36 a year. That's very similar to Ring pricing, and quite a bit cheaper than the $5 minimum tier for Nest. Personally, I would gladly pay an extra $100 premium for an Arlo Video Doorbell with on-device AI (we shouldn't need the cloud to tell the difference between people, cars, and dogs) and local storage, but at some point I have to stop faulting Arlo for shifting its business model.

    There's still room for improvement here, and I would kill for proper Assistant integration, but all in all this is a full-featured, competitively priced doorbell that compares favorably against the most popular models out there.

    Let Inga Tell You: Curse of the intermittent technical problem – La Jolla Light - January 17, 2020 by admin

    LET INGA TELL YOU:

    Is it just my imagination, or do I spend an inordinate amount of time getting stuff fixed? Something is always broken, whether its a computer problem, a funny noise the car is making, a cracked sprinkler head, or an ice-maker that isnt making ice. Even our security cameras decided to fog up for no known reason.

    Of course, I couldnt help but notice that a lot of the stuff Im getting fixed wouldnt have needed fixing in my youth because it didnt yet exist (like computers). Or didnt exist at my house (like ice-makers, sprinkler heads and security cameras). There was a lot to be said for the era of manual typewriters, hand-washed dishes, ice cube trays, and a climate where it actually rains.

    But the true insanity-making problem to fix is the intermittent one. Just as intermittent reinforcement is the quickest way to strengthen a desired behavior, an intermittent technical problem that absolutely refuses to manifest itself in the presence of an entity actually qualified to fix it is the fastest way to make people bats*!#t crazy.

    Cars, of course, are notorious for this. Im sure if you are in the auto repair biz, there is nothing you hate more than a person like me bringing in a vehicle that is making a funny noise.

    What kind of funny noise? they ask patiently. Is it more like a knocking, or a squeaking, or a clunking?

    OK, clunking.

    They take the car out for a test drive. Does it clunk? Not a chance. Cars are designed to never clunk on command. They only clunk again on your way home.

    Our heating system has developed a whine. It is annoying beyond belief. But the alternative is being cold. The heating guy has been out twice and the system purrs like a happy kitten when he is on the premises.

    So that brings us to the problem of the pictures on both of our TVs tiling (also known as pixelating.) The picture will suddenly break up and get totally fuzzy and unwatchable, always, maliciously, at some critically important point in a program or sports event. The fact that it happens on both our TVs, which have two different cable boxes, suggests that its not the TVs or the cable boxes, but something to do with the cable itself. We allowed it could always be transmission issues from the channels themselves. But surely our cable company could troubleshoot this for us?

    Our cable provider sent out a gentleman named George, who had the social skills of a sock. Unfortunately, the technical skills of one, too.

    Let me just say we have actually had some very good people come out over the years to deal with the various cable problems at our house. We have also had a fair share of the ones who wish to get out of your home with the greatest possible expedience and least possible service. I really wish you could give Yelp ratings to cable guys. Theres a bunch Id like to see re-employed in trash pickup.

    George showed up during our early afternoon appointment window and turned on the TV sets. No pixelating or tiling was occurring. He tested the signal on our cable box and pronounced it fine. But, of course, as we noted, the problem was intermittent. Olof mentioned that our cable installation had been done some years ago so we wondered aloud if the wiring was getting a little corroded at this point, especially being so close to the ocean.

    George, however, insisted that he cant send a maintenance technician out to look at a problem that he cant see on the TV. He suggests and we were a tad incredulous that we reschedule for a service call for an evening time when this problem was occurring.

    Olof, who is a far nicer person than I, reiterated that we notice this problem in the evenings because that is the only time that either of us ever watches TV. Could very well be happening at other times, too.

    I, a far less nice person than Olof, queried if the technician would be joining us on the couch for the evening hoping the screen would break up. (I offered to make popcorn.)

    But George just shrugged. He left. And our TVs continue to sporadically pixelate.

    I couldnt help but reflect that in my youth, TV picture problems were solved by adjusting the rabbit ears on top of the set. It helped, or it didnt help. But it was vastly less aggravating.

    So now Ill take the route I should have taken in the first place: crowdsourcing. Anybody out there having this problem, too? Were you able to fix it? Olof is hoping to find out before our TV screen disintegrates during the last five minutes of the Super Bowl.

    Risk assessments and the new battery standard – EcoGeneration - January 17, 2020 by admin

    By the time this article is published, AS/NZS 3000 (known as the Wiring Rules) may have been amended. If it hasnt been, the people in the know say to expect it shortly. This means that the existing reference in section 7.3 (which calls out the standard to follow when installing batteries) will change to AS/NZS 5139, the new battery standard.

    Most regulators are waiting for the amendment to the Wiring Rules before mandating AS/NZS 5139 but some regulators, such as those in Tasmania and Victoria, have already called it up. Either way, it is time to get on board and familiarise yourself with the standard.

    The standard AS/NZS 5139 is like three standards in one, with the section that you follow depending on the battery you are installing. Sections 1, 2, 3 and 7 in the standard must be followed for all battery installations, and:

    There are many rules that are unique to the specific battery you are installing. However, there are some blanket rules that need to be followed regardless of the type of battery. One of these blanket rules is the requirement to complete a risk assessment.

    Most good businesses are accustomed to completing a safe work method statement or job safety analysis before they start work. This typically involves assessing the high-risk activities on the job site and planning a safer way to complete them.

    For example, on many battery installations you will need to park your vehicle on a road to unload the battery. Working on or near roads can be a high-risk activity because there is the potential for workers to be struck by vehicles traveling at speed. Therefore, before starting work you need to consider the inherent risks of this part of the job by describing the hazard, which is the first step of the risk assessment process.

    I know it may seem a bit macabre, but it is necessary to assess the inherent risks by making a judgement on the consequence of what would happen if you got hit by a car and the likelihood of this actually happening at the site you are working at. The multiplication of likelihood and consequence give you an inherent risk rating, which is the second step of the risk assessment process.

    The third step is assessing the way to minimise this risk. In many instances, you cannot reduce the consequence level, but you can reduce the likelihood. In the example where a car could hit a worker, several controls could be implemented to minimise the likelihood of this happening, including wearing high visibility clothing, implementing traffic management and using spotters.

    Once you implement these controls, you can carry out the fourth step by re-assessing the original inherent risk to get a residual risk, which is lower and thus makes it safe to do your job. You then complete this process for every high-risk activity.

    This is just one stage of the risk assessment required by AS/NZS 5139. The other stage requires you to consider the risks associated with the battery system itself. The CEC is calling this stage of the risk assessment the site-specific battery system component, and this is the part that relates to AS/NZS 5139.

    When reading AS/NZS 5139, it helps to have a solid understanding of the risk assessment process, so it might be worth paying a bit more attention to the mechanics of the process next time you are completing a safe work method statement or job safety analysis. There is also an explainer of this in appendix G of AS/NZS 5139, and the CEC has produced a diagram to help you understand how the risk assessment process is integrated into the standard.

    The process of completing the risk assessment is the same as for a safe work method statement or job safety analysis, but the subject matter is slightly different to what most tradesmen will be used to. The first step of describing the hazard is systematically presented in AS/NZS 5139 Section 3. Table 3.1 lists the common hazards in batteries that can be seen in the diagram included on this page.

    The second step of assessing the inherent risk is to be completed by the installer. You need to ask yourself, what is the consequence of the hazard? This depends on the battery chemistry and product characteristics being installed, so getting this from your battery manufacturer is essential. You also need to exercise a bit of judgement to determine the likelihood of something going wrong with the battery in the location you have chosen to install it.

    The third step in the risk assessment process is nominating the controls for each hazard. I mentioned earlier that AS/NZS 5139 is like three standards in one, depending on the battery you are installing. Each one of these standards gives you the controls to follow for that battery type and they are written to correspond to the hazards in Section 3.

    The fourth step is to assess the residual risk. Like step two, the installer needs to re-assess the risk based on the installation with the control measures in place.

    The CEC has released a sample risk assessment template for installers to use when installing CEC approved batteries. Please go to the installer section of our website for a copy.

    For a list of CEC approved batteries, jump onto the products section of the CEC website. If you want more clarification on this, I would encourage you to log into the installer section of the CEC website and watch the Toolbox Talk called AS/NZS 5139: An overview.
