Rather than continuously recording data, a VMS may also implement motion detection to reduce the amount of data to be recorded.
In older analog security camera systems, the cameras were "dumb" devices only capable of producing a video signal continuously, and any video signal processing had to be done by the recording VMS. With modern megapixel network cameras, the cameras are much more sophisticated.
Motion detection can now be distributed, so that the cameras do motion detection themselves and only send video when motion is detected.
Alternately, motion detection can still also occur in t
