Video motion detection (VMD) can identify motion without using a motion detector. It uses software to identify motion in the images based on changes in brightness and colour. VMD cameras must be set up correctly to avoid false alarms.
How does video motion detection work?
With Bell Smart Home video services, you can adjust the sensitivity to motion and the size of the targets captured by your cameras. The camera can have three VMD windows. When it detects motion within these windows, it starts recording.
