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. Yes, a siren is very helpful in alerting you to a fire, but doesn't provide any information other than that. Nest Protect is different in that it
also provides spoken alerts, which not only tell you the nature of the emergency smoke or carbon monoxide, but also the room in which it's occurring. The Nest Protect runs self checks to ensure that everything is working as it should; while this includes turning on its siren once a month, it's a welcome feature.

The basic home security package comes with one motion detector,one HDvideo camera, a fire detector, 6 window and door monitors and a remote keyless door lock. Additional equipment, such as glass break detectors and carbon monoxide alarms, can be purchased separately and added to the system. As with many other modern alarm systems, the customer can monitor the system remotely via their smart phone or other electronic device. Additionally, the system can be set up to control the
heat, lights, and locks in the house remotely as well. They can generally detect motion from 40 to 80 feet away and can be connected to your home alarm system or to a security camera. There are two main types of home security motion sensors: active detectors,whichemit light, sound or other
forms of energy and recognize when that energy is being disturbed; or passive detectors, which recognize incoming signals sent from the disturbance, such as heat or sound waves.
