One of the great things about motion detection is that your camera still works for you in the background even when you’re away or logged out of the system. The best way to understand how motion detection works is to first look at how a camera functions. Inside every camera is the image sensor which the lens of the camera directs light to. 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.
