Wireless Motion Sensors:
Today, most motion sensor passives and beams are wireless. Wireless passives and beams are very easy to set up. They do not require drilling, and they communicate with the other security system components wireless transmission.
Wireless Door & Window Contacts.
Most Wireless contact motion sensors are passive infrared sensors. They trigger an alarm if the protected door or window is opened while the system is armed.
Pet Immune Passive Motion Sensors:
A passive infrared sensor can be set up to ignore animals up to a certain weight. A dual technology motion sensor is more resistant to false alarms caused by animals because it requires two sensors to be triggered in a manner determined by the manufacturer. They can be set up to ignore a large animal or multiple small animals without setting off a false alarm. Some pet immune motion sensors have a sensitivity level that can be adjusted for families with very active animals.
Video Motion Sensors:
Combines video cameras with advanced signal processing. Some recordable motion sensors start recording when they sense motion. Cameras controlled by motion sensors can save you memory storage by not recording hundreds of hours of useless footage—they only capture the important stuff.
