Dynamic sensitivity (explained)

Motion detection is by default set up for dynamic sensitivity. To adjust the sensitivity level manually, see Enable manual sensitivity.

Milestone recommends that you do not enable manual sensitivity because:

With dynamic sensitivity, the system calculates and optimizes the sensitivity level automatically and suppresses the motion detections that come from noise in the images.
Dynamic sensitivity improves motion detection at nighttime, where the noise in the images often triggers false motion.
The system is not overloaded from too much recording.
The users are not missing results from too little recording.
