The moment light reaches the image sensor, pixels then record how much light they receive. These dark and light areas then form the video images that we see. Motion detection works by comparing successive video images. So if the pattern of light changes between frames a change in pixels the smart camera concludes that something has moved and starts to record. As it begins to record, it also sends you an alert. The camera determines when enough has changed based on the motion detection settings see below. There are different methods of motion detection, i. e. infrared heat vision and microwave. We won’t get too much into the deeper technical aspects in this piece. The basic principle is the same for most cameras.
