Chapter 9 VCA Alarm
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.
For HWD-7100MH and HWD-7200MH series DVR, if enhanced VCA mode is enabled,
full-channel line crossing detection and intrusion detection, and 2-ch sudden scene change
detection are supported, but 2K/4K output and 4 MP/5 MP/8 MP signal input are not
supported; if enhanced VCA mode is disabled, 2-ch line crossing detection and intrusion
detection, and 2-ch sudden scene change detection are supported, and 2K/4K output and 4
MP/5 MP/8 MP signal input are also supported.

enhanced VCA mode is enabled. HWD-6216MH-G2 series also support 1-ch sudden scene
change detection. Channels with audio support audio exception detection.
