1.8.5.5 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.
⚫ 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.
