Welcome to the
Doktor Jon does his bit to help
Sticking with the subject of Town Centre Closed Circuit TV schemes, Doktor Jon would like to perhaps broaden the scope of what has already been outlined on previous pages.
Consider if you will the cost of setting up an average CCTV control room; you probably dont want to know, but lets just say that it could pay for an awful lot of overtime.
Now, lets consider for arguments sake that an average TC scheme might have twenty cameras distributed (normally at major road or pedestrian intersections) throughout the area.
At the moment, a patrolling vehicle is absolutely reliant on clear communication from the control room, to make any sense of what is happening on the ground.
What if .... instead of pictures only going to the control room, they could actually be displayed in the patrolling vehicles.
How difficult would that be to achieve; well actually its not difficult at all.
Using conventional off the shelf transmission equipment, a cluster of cameras could be broadcast from a hub on a police use only microwave frequency. If necessary, the images could be scrambled to remain secure, and the decoding and display equipment packed into a portable unit for use in different vehicles, or on different shifts.
In fact given the rapid advancement in IP network enabled video servers, it is already quite feasible to relay pictures using wireless digital data networks, to a suitable laptop, notebook or PDA computer ( a technique known as a 'mesh network').
