Meet the D-Link HD Covert Network Camera: a tiny device that lets you keep watch over an area discreetly. Just place it where you want to monitor things, and you can track motion events. The HD Covert Network Camera has a two-piece design, so you can place the camera away from the control box.
The camera has a 720p HD sensor. It provides you with high-resolution snapshots and videos. It supports multicast H.264 and MPEG-4 streaming. More info is available here.
