Enable VCA Information Overlay
In the live view, only the analog cameras support VCA information overlay.
Enable VCA function first before showing the VCA information. Refer to
Chapter 9 VCA Alarm
for
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.

Management System) software, in order to decrease the bandwidth requirement without affecting the
image quality, channel-zero encoding is supported as an option for you.
