What Motion Detection means in CCTV system??

Motion detection camera recording is actually a function of the surveillance DVR and not the camera. Motion is detected by changes in the pixels of the images that are sent to the DVR from your security cameras.  

If there is any motion in the configured detection area, the camera will automatically detect the event and can trigger preconfigured alarms or recording. Users can set sensitivity level, detection area, and arming schedule accordingly.
