Motion Sensors Brattleboro VT
Video security cameras (or Digital CCTV systems) with sufficient sensitivity can be set up to monitor a room digitally. If a person enters the room, the security software records a change in the image the camera is viewing, which trips the alarm.
The detection then isn't a function of the sensors, it is the microprocessors and computer software analyzing changes in the video image.
Some systems ( netcam surveillance ) lets you use a video camera connected to your PC and when motion is detected, your software program will notify you by email anytime movement is detected. Advanced features include live streaming video, multi camera support and motion-activated video clips whenever motion is detected.
