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.

7. To harness the full potential of the smart home automation, disparate manufacturers will have to develop technologies based on common open standards. Very few, if any, firms produce every device found in a household, and it is unlikely that consumers would be brand loyal enough to buy every household device, or even a majority of them, from a single manufacturer. So if manufacturers want to ensure that their devices talk to others, they will have be developed under common standards – standards also shared between software companies. This level of collaboration may take some time – many of these firms are direct competitors after all, but it is necessary. One of the ways Vivint is trying to separate from the competition is by positioning themselves as more of a ‘home automation’ solution. Their mobile app allows you to control your home security system remotely. They also have a suite of additional home automation products and features that allow you to control your thermostat temperature to promote energy efficiency, lock and unlock doors, live stream video of your doorbell ringing and the surrounding area, etc. Their home automation is compatible with common smart home products, such as Amazon Echo, Google home, Amazon Alexa, and many more. There are many negative Vivint reviews from customers, the majority of them noting poor customer service. Be sure to check out the Vivint smart home reviews and home security reviews below to see what customers have to say and to decide if Vivint is the right home security provider for you.
