Also helpful is that the light will briefly turn on at night if it senses motion, to help you see your way in the dark. Installation and SetupTo install the Nest Protect, you first screw a base plate into the ceiling, and then attach the main body of the smoke detector onto the base plate. Then, you connect to it using the Nest app on your smartphone Android and iOS, specifying, among other things, in which room the Nest Protect is located. It's a fairly simple process that took me about 5 10 minutes. MORE: Top Rated Wireless Home Security CamerasLike most smoke detectors, you can purchase the Nest Protect as either a battery powered model, or one that’s hard wired. App and PerformanceThe Nest Protect uses a split spectrum sensor that Nest says is good at detecting both slow smouldering fires as well as fast burning ones. It's a photoelectric sensor, which is generally better at sensing smouldering fires ionization sensors are faster at quick burning fires, but are more prone to nuisance alarms, but Nest's sensor has a second wavelength that's better for picking up flaming fires. In addition, the Nest Protect has sensors for carbon monoxide, heat, humidity and occupancy. In our lab, we tested the Nest Protect as with all smoke detectors by spraying an aerosol smoke detector tester spray from 5, 10 and 15 feet away, and timing how long it took each alarm to go off. At the 5 and 10 foot mark, the Nest Protect sounded after 18 seconds. At 15 feet, the alarm activated after 28 seconds.

Impact: There are some key differences between Samsung's previous offerings in the space, those sold under Hanwha's WiseNet branding, and Samsung's newly patented doorbell camera. The biggest of those is the inclusion of two separate camera sensors. Samsung has been including two cameras in several of its big name products over the past few years and their inclusion here isn't surprising. On smartphones, the company generally uses two sensors to accomplish more accurate depth perception while other companies have used a similar setup to attain more accurate facial recognition features. The latter of those could be the reason for two cameras to be used here since that would enable any AI driven features based on that to work more effectively. The inclusion of full color renders, meanwhile, seems to suggest this product is actually significantly far into development rather than only existing as a concept — although that could turn out not to be the case.
