Figure 48, Enable VCA Information Overlay
In Live View, only analog cameras support VCA information overlay.
Enable VCA function before showing the VCA information.
VCA information is hidden by default. If the connected analog
camera does not support VCA, the icon displays grey and cannot be
operated.
For analog cameras, the VCA information includes line crossing
detection and intrusion detection.
The DVR supports VCA information overlay of only 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 with
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.
