Field Name Description
Sensitivity(1-100) Determines how sensitive the camera reacts to the movement. The higher
the sensitivity level is, the smaller motion will trigger the alarm, but may give
false alarms. Default is 70.
Timer(0-300 secs) The interval before the next motion detection can be triggered again. Default
is 1 second.
Threshold (%) The threshold level of this motion detection region. The lower threshold level
is, smaller portion of the region would be considered as motions, which is
more easily to be triggered, but may give more false alarms.
