Purpose
The DVR can receive the VCA alarm (line crossing detection, intrusion detection, sudden scene
change detection and audio exception detection) sent by analog camera, and the VCA detection
must be enabled and configured on the camera settings interface first. All other VCA detection
features must be supported by the connected IP camera.
5MP non-real time series support line crossing detection and intrusion detection of all
channels, and 2-ch sudden scene change detection. Channels with audio support audio
exception detection.
1U 3MP non-real time series support 4-ch line crossing detection and intrusion detection.
16ch models also support 1-ch sudden scene change detection. Channels with audio

For the analog channels, the line crossing detection and intrusion detection conflict with

detection. You can only enable one function.
