?This First Alert Wireless Security Passive Infrared Motion Sensor is integrated with a wide range of latest technologies to enhance the sensitivity and identification capability of the device. The adaptive microwave system can curb the false alarms caused by running of machine or other device. The identification technology can distinguish the different signals of invader and pets£¬ so as to reduce effectively reduce the false alarms caused by moving pets in your house or office. The superb anti-cloak technology can identify any disguised intruders. Combined with microwave and passive infrared technology£¬ the detector has a better ability in signal processing. Other technologies include K-wave band£¬ adjustable digital pulse counting£¬ auto temperature compensation£¬ anti-demolition£¬ DMF and DMT technology.
