Parameter Description
PIR Alarm
PIR function helps enhancing the accuracy and validity of motion detect.
It can filter the meaningless alarms that are activated by the objects such
as falling leaves, flies. The detection range by PIR is smaller than the field
angle.
PIR function is enabled by default if it is supported by the cameras.
Enabling PIR function will get the motion detect to be enabled
automatically to generate motion detection alarms; if the PIR function is
not enabled, the motion detect just has the general effect.

Only when the channel type is CVI, the PIR function can be enabled.

If the camera does not support PIR function, it will be unusable.
