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. Moreover, it was the only device to pass all of our tests.

“By creating one versatile ecosystem, the homeowner instantly understands the capabilities and they’ll become hooked,” he says. “Similar to the original remote control, being able to answer the door, and potentially unlock it, from the comfort of your couch or office creates an immediate purchase decision. ”This presents one of the tradeoffs mentioned earlier, in that analytics are going to have a much heavier draw on power and will sometimes preclude the use of battery powered cameras. “Video analytics is much harder to do with batteries,” Child says. “Video analytics is pretty process intensive.
