Chapter 9 VCA Alarm
Purpose
The DVR can receive a VCA alarm (line crossing detection, intrusion detection, sudden scene change
detection, and audio exception detection) sent by an analog camera,. The VCA detection must first be
enabled and configured on the camera settings interface. All other VCA detection features must be
supported by the connected IP camera.
The DVR supports full-channel line crossing detection, intrusion detection, 2-ch sudden scene
change detection, and audio exception detection.
For the analog channels, the line crossing detection and intrusion detection conflict with other VCA
detection such as sudden scene change detection, face detection, and vehicle detection. You can
enable only one function.
