There are some restrictions on installation, with cameras not being installed in an area where there is a "reasonable expectation of privacy", such as bathrooms, gym locker areas and private offices unless consent by the office occupant is given. Cameras are generally acceptable in hallways, parking lots, front offices where students, employees, and parents come and go, gymnasiums, cafeterias, supply rooms and classrooms. The installation of cameras in classrooms may be objected to by some teachers. There were an estimated 30 million surveillance cameras in the United States in 2011. Video surveillance has been common in the United States since the 1990s; for example, one manufacturer reported net earnings of $120 million in 1995. With lower cost and easier installation, sales of home security cameras increased in the early 21st century. Following the September 11 attacks, the use of video surveillance in public places became more common to deter future terrorist attacks. Under the Homeland Security Grant Program, government grants are available for cities to install surveillance camera networks. In 2009, there were an estimated 15,000 CCTV systems in Chicago, many linked to an integrated camera network.

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.
