You can schedule alarm reporting and set actions that can be triggered by other devices so that
alarms and the triggered actions can be handled in time.
Alarm reporting can be scheduled for a motion detection alarm.

Motion detection detects the object motion in a specified rectangular area during a period. You need
to set a detection area, sensitivity of detection, object size, and history for the camera to decide

Sensitivity
and
Object Size
for the camera to decide whether to report a
motion detection alarm.
•
Moving the slider to the right increases detection sensitivity. When the extent of motion
within the detection area exceeds the set object size, the camera reports an alarm.
•
Object Size
specifies the minimum ratio of the object's size to the size of the total
detection area before an alarm will be reported. That is to say, to detect motion of tiny
objects, you need to draw a small box (detection area) in the actual motion area
accordingly.
•
Motion Detection
results are shown in real time. Red lines represent the raised motion
detection alarms. The longer a line, the greater the extent of motion. The denser the
lines, the greater the frequency of motion.
5. Set the alarm parameters for duration of alarms.
