This web page contains information on the vibration and temperature of the unit and can be used for system
diagnostics.
Camera Masking
TransVu 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.
This web page allows the masking feature to be configured.

Description
This displays the camera number and camera title as configured on the
Camera Setup page.
Enables or disables the feature on the camera.
This figure corresponds to the contrast threshold the system uses to define
that a camera is masked. The default setting is 30, but as different
cameras have different characteristics, it will be neccessary to adjust this
figure to avoid false alarms.
This is the delay the unit will wait before declaring the camera is masked.
