remote security cameras 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. As it begins to record, it also sends you an alert.

The problem with cameras that can see through glass is that they might pick up plants moving around on a blustery day, or passing vehicles even.
