DESC: You can check a site only when something moves, such as when a person enters or leaves the area under surveillance. When the camera detects movement, it shoots a still image, holds the image temporarily in internal memory, and sends you a copy by email2 or FTP transfer. You can set the camera to snap a shot whenever a door opens or closes, for example, or at pre-set times. This system is more convenient than tape systems because you don't have to fast-forward or rewind to find a particular image.
