Masked Cam Det
The unit has the capability to identify if a video input has been covered (by hand, spray paint, etc.)
to prevent video images being viewed and recorded. The Camera Masking option identifies normal
levels of contrast and uses them as a base line. It then compares these against a user defined
minimum contrast level. If the video input goes below this user defined level an event is generated
on the unit.
