DS 924/924P Wireless PIR Motion Detector
A Passive Infrared (PIR) Motion Sensor is designed to detect movement in
the interior of a structure by sensing the Infrared energy emitted from the
human body as it moves across the Sensor's field of view. When motion is
detected the unit sends an alarm signal to the Control Panel. The DS924/
DS924P are high performance PIR Motion Sensors which use advanced
signal processing to provide outstanding catch performance and
unsurpassed false alarm immunity.
