4.8.5.5 PIR Alarm
When the detected scene has changed, system can generate an 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.

not enabled, the motion detect just has the general effect.
