4.8.5.5 PIR Alarm
Background Information
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.
