8GHz frequencies such as the one found in this outdoor wireless security camera. These RF or Analog wireless transmitters were limited to clear line of sight, meaning there must be a unobstructed view between the antennas connected to the receiver and transmitter. While this requirement was doable for outdoor applications, it made it impossible to use these devices for other applications because of interference from obstacles. The main advantage of using analog video transmitters which still holds true today is for Real Time video transmission; if you
want delay free video for a manufacturing process then they are still the equipment of choice. The recent advancements in cmos camera sensor technology have allowed great
reductions in pricing for megapixel IP cameras, thus enabling the average consumer to afford high definition video. At the same time, prices for wireless access points have become affordable and WiFi radio technology has become more reliable.

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.
