Video analytics
VCA (video content analysis) is the computerized analysis of video to detect events of
interest. This function is only available on the TVN 21S. When the function is enabled,
the recorder can handle VCA alarms generated by Interlogix cameras that support the
VCA feature.
To enable the function, go to Camera Management > VCA. You can then set the
trigger channel, schedule, and rules for the analysis. For further information on these
options, see “Motion detection schedules” on page 89.
Setting up system notifications
Setting up system notifications instructs the recorder to alert you when irregular events
occur and how to alert you to the event.
You can quickly check the system status by looking at the status LEDs on the front
panel. When there is an irregular event with the system, an icon appears on screen to
also alert you. See “Status information” on page 29 for further information.
The system notifications include:
• HDD Full: One installed HDD is full (overwrite option is disabled).
• HDD Error: Errors occurred while files were being written to the HDD, no HDD
installed or HDD had failed to initialize.
