The camera ’s default sensitivity is 70 and threshold is 10%. By these default values, only
the rabbit and the turtle would trigger an alarm while the butterfly and the snail would be
ignored by the motion detection system.
Important: Please remember that changing the size of the motion detection region has an impact
on the threshold – the bigger is the size of the motion detection region the smaller should be the
threshold value if you want the same object size to trigger motion. For example, if you increase
the motion detection region to twice the previous size, please remember to reduce the threshold
to half its original value (from 10% to 5%). On the other hand, changing the location of the motion
detection region has no impact on threshold.
Trigger interval
The last configuration item is the trigger interval. It is the time period from the beginning of the
triggered event during which the all motion activities are ignored by the camera. This is designed
to avoid needless repetitive reporting of the same intrusion. Trigger interval 20 seconds would
mean that when the even happens, camera will take certain one-time actions and ignore the
continuing activity in the motion detection region for 20 seconds. When 20 seconds are over, the
camera will produce a new alarm if there are still action in the motion detection region, and take
actions again.
