I originally gained interest in finding a quality "smart" doorbell
following a string of package thefts and strange dudes loitering in our community. I truly value the ability to see exactly what is going on in front of my house, to be able to verify if a package was delivered, and to be notified if someone is lingering at my front door. For these reasons and more I have been researching and comparing "smart doorbell"
products since the first models hit the market a few years back. Our household has been through a SkyBell original, SkyBell 2. 0, Ring, and now the SkyBell HD I plan to stick with this one. The first two 2 iterations of the SkyBell product were just so so.

63 x 5. 28 inches and the install process follows the same steps: after choosing the rooms in
which you’re going to install the Nest Protect at least in every room which has a fuel burning appliance, you need to make sure there is a minimum of 10 feet from any cooking appliance and avoid placing it on a corner you can choose either a wall or the ceiling. Then, you need to take the provided backplate and fix it to the wall/ceiling using the four screws and afterwards, just connect the smoke detector to the backplate using a circular motion if you have the wire powered version, the installing process also includes connecting the device to a power source, but, it’s ideal
that this is done by a qualified person, to make sure the installation is made in accordance with the country or state’s regulations. The way to differentiate the first and the second generation of Nest Protect is by verifying if it has a battery door the Nest Protect 1 does not have one, verify the back plate the second generation has a round backplate, while the first has a square plate and the easiest one is to look at the edges of the device the second generation has rounded corners all around the case, while the first gen has straight edges. Right now, on the market, there are three types of smoke detectors: those that use ionization sensors, those that use photoelectric sensors and lastly, those that use both type of sensors also called dual sensor smoke alarms. The Nest Protect, theoretically, falls into the last category, but things are a bit more complicated because it doesn’t have a ionization sensor, but it does use the Split Spectrum Sensor which nullifies the need of the radioactive ionization sensor as you know, it detects smoke produced by flaming fires which burn at a fast rate so, if the ionized air is disrupted by smoke, it triggers the alarm. The photoelectric sensors is used to detect any smouldering fires that uses a light beam which, normally does not hit the sensor, but when smoke scatters the light particles, it will hit the sensor, therefore triggering the alarms – this method is used to detect a fire in its early stages, therefore reacting a lot faster. Now, the Split Spectrum Sensor should detect both the flaming fires and the smouldering ones, by adding a blue LED light at a wavelength of 450nm to look for small particles which are an indicator of a rapid, fast burning fire and keeping the usual photoelectric sensor to detect smouldering fires. To make sure it doesn’t repeat the mistakes of its predecessor annoying false alarms, the new sensor is isolated from any outside light and the encasing is designed to only allow smoke in and nothing else this worked just fine since the second generation of Nest Protect is indeed less prone to false alarms. Besides the Split Spectrum sensor, there’s also an Electrochemical carbon monoxide sensor yes, the Nest Protect is also a Carbon Monoxide Detector which detects the CO concentration level inside the room and, if it’s beyond safe levels, it triggers the alarm CO detectors usually last about 6 7 years, but Nest advertises that the sensor on the Protect can last up to 10 years. Furthermore, there’s also a heat sensor so you’ll get notified when the home gets either too cold or too hot, a humidity sensor so it makes it unlikely that the alarm will be triggered when there’s lots of steam, an ambient light sensor so the detector knows when the lights are shut off and it can activate the Pathlight feature or the Nightly Promise – the LED will be green if everything is fine, otherwise, it will become yellow and an occupancy sensor it is used with the Pathlight feature, so it will detect movement and will shine a light on your path during the night – so you don’t stumble on the furniture.

Nicely done. @phone users who comment That nifty "reply" feature where your comment
appears immediately below the comment you are replying to does not work on any other platform. As a result, your conversational reply looks like a total non sequitur to everyone else. If you
want us to understand your comments you need to, at a minimum, use the @ convention. As is not unusual, pretty much with Rex here. Well done for what it is, but I'm not much in to humor that was old timey when I was young. The puzzle has a certain Hee Haw/Lawrence Welk feeling to it. I did enjoy the WKRP clip.
