As with all sophisticated eletronic components, periodic adjustments to a camera
may be required to maintain its optimum performance. These adjustments
must be done manually on most cameras. Newer cameras permit adjustments
to be made electronically from remote locations, and the benefits of this are
clear:
- Immediate corrections can be made as required
- Adjustments are instantly made from one central location
Consider a camera mounted on a pole in a parking lot. A technician can
make adjustments to this camera with no concern for the weather, and without
having to climb a ladder or use a lift. Valuable time is saved, the chance
of injury reduced, and there are fewer interruptions to the security operation.
For example, Bilinx Bi-Directional Communication technology from Bosch uses
conventional CCTV coax, unshielded twisted pair (UTP) and fiber optic video
transmission links to communicate data to and from the camera. Bilinx
technology embeds control and configuration commands in the video signal, enabling
many functions that used to require direct camera access or separate wiring
to work over a video cable.
