SECTION 6
VCA Features
Alibi recorders can configure Video Content Analysis (VCA) features supported by Alibi cameras.
Alibi cameras that include VCA features usually do not include all features. After selecting a camera in the VCA menu
(
Menu | Camera Management | VCA
) only those VCA features supported by the camera will be available (highlighted).
When VCA features are configured by a recorder, the settings are saved in the camera. When an VCA event occurs, the event
information is sent immediately to the recorder, and acted upon by recording live video, full screen monitoring, generating an
audible alarm and/or sending email.
The ALI-NVR71128R recorder supports the following VCA features. Additional VCA features shown in the display are not available at
the time of this printing.
•
Face Detection

crosses the line from one side to the other (side A to B), vice versa (side B to A) or either way. You can define up to 4 line
crossing conditions in the same video channel.
•

space within the quadrangle. You can define up to 4 intrusion regions in the same video channel.
