| CCTV (Closed Circuit TV) |
|---|
| A surveillance system - commonly used in security applications - where the video signals are not publicly distributed. Cameras are connected to television monitors in a limited area such as a bank, a museum, a store, or a parking lot. CCTV video is often of very low quality - usually black and white – and more sophisticated systems in sensitive installations may be connected to frame grabbers recording at very low frame-rates (typically, around one frame per second, or even slower). |
