NOTE
:
When recording to a Digital Video Recorder, the DVR may indicate a Video Loss as the monitor
sequences between channels. This Video Loss occurs because the monitor’s switching
function is analogue, whereas the DVR is a digital product. Therefore a synchronization
problem will result.
The Solution to this problem is to adjust the Video Loss alarm sensitivity setting to 3 frames
on your DVR unit, or simply disable the video loss function on your DVR. Please contact the
manufacturer of your DVR if you require further assistance.
