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.
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.
Step 1 Select
