9 VCA Alarm
ATTENTION!
Some of the features described below require special cameras. Not all features work
with
all cameras. Please contact your Hikvision Sales Expert for more information.
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.
HUI series supports line crossing detection and intrusion detection of all channels, and 2-ch
sudden scene change detection. Channels with audio support 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 only enable one function.
9.1 Face Detection
Purpose
The face detection function detects faces appearing in the surveillance scene, and certain
actions can be taken when the alarm is triggered.
1. Go to Menu > Cameras Setup > VCA.
2. Select the camera to configure the VCA.
3. You can check the S
ave VCA Picture checkbox to save the captured VCA detection
pictures.
