4.2 PIR function
Passive infrared (PIR) detectors are widely used, including in alarm systems for motion detection. The
operation of the sensor is based on the precise measurement of the temperature of objects in a specific
area, and each change of this temperature is interpreted as motion by integrated electronics. The task of
the PIR detector in the camera is to limit the number of false motion detection alarms.
The PIR detector, working in conjunction with the motion detection function, detects moving objects
with a temperature higher than the ambient temperature. It is only the simultaneous detection of motion
by the PIR detector and the motion detection function that generates an alarm event. In this way, the
PIR sensor significantly reduces the number of false motion detection alarms related to light flashes,
snowfall, insects or day / night switching.
