On the contrary, some security camera providers offer cloud storage monthly plans to securely store videos on the cloud. You can easily access them anytime, anywhere by signing into your account on your mobile device or using a mobile app. Some systems also record to DVD or mini disc, but most are now transitioning to DVR digital video recorder technology. A computer based camera system records your video to the PC’s hard disc, making it fast and easy to review your video history.

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.
