Channel-Zero Encoding - RainVision UDVR Series User Manual

 In the live view, only the analog cameras support VCA information overlay.
 Enable VCA function first before showing the VCA information. Refer to Chapter 10 VCA
Alarm for the detailed operation.
 The VCA information is hidden by default. If the connected analog camera does not support
VCA, the icon displays grey and cannot be operated.
 For the analog cameras, the VCA information includes line crossing detection and intrusion
detection.
 The DVR only supports VCA information overlay of one channel. If you enable the function
of one channel, the other channels will disable the function automatically.
 Both single window and multi-window display modes support VCA information overlay.
 Only the main output supports VCA information overlay. When switching to the aux output,
the VCA information overlay of main output is disabled.
 For the analog cameras, if the camera number does not exceed the limit for line crossing
detection and intrusion detection, the VCA information overlay can be enabled for all the
analog cameras enabled line crossing detection and intrusion detection. If the camera
number exceeds the limit for line crossing detection, intrusion detection and sudden scene
change detection, only the cameras enabled line crossing detection and intrusion detection
support VCA information overlay. Disabling line crossing detection and intrusion detection
remotely will not affect the VCA information overlay in the local live view.
