Motion detection surveillance cameras

Motion detection

— the motion-detecting system in the frame can be used in various ways: when the sensor is triggered, the device can send a notification to the user, automatically start recording, focus on the moving object, "track" it with the lens (in models with PTZ, see the relevant section), etc. In any case, detection reduces the risk of missing an important event in the frame. It can also provide other benefits — in particular, automatic recording activation upon motion detection significantly reduces the volumes of recorded materials.
