Setting up Video Motion-
Detection
The NetVision system can detect motion within
video frames, and record automatically when
motion is detected during scheduled times
(default: 'always'). Video motion detection is
fully customizable for each camera including
the detection zone(s) within the camera view,
sensitivity, and recording duration.
Video motion-detection can also trigger:
• An email or alarm-alert;
• A camera to display automatically (and
optionally point to a specific 'preset'
location);
• Special (alarm overlay) subtitles to display;
• The ‘TV-Out’ feature (Spot Monitoring).
