So would you like to play "Spot the CCTV Camera?". Eagle eyed visitors may recognise the profusion of street furniture, surrounding a single heritage dome camera keeping watch over part  of Londons' prestigious Oxford Street shopping area.

If it's video switchers
that really turn you on...


Constant changes with Video Switchers

If you decide to build a CCTV system with anything more than a single camera, at some point decisions need to be made about how best to display all the available images.

Display Multiplexers in all their various guises, have in recent years increasingly found favour as the main ‘hub’ for enabling an effective display system. And yet the dear old video switcher has been around for an awfully long time, and will hopefully remain as an essential tool in the system designers armoury, for very many more years to come.

lf you thought that the sum total of a CCTV switchers abilities depended simply on the push of a button, hopefully Doktor Jon will be able to provide a little more insight.

Manual Video Switchers - digit all power at its most basic. Simple manually selected images can play a pivotal role in even the most complex of CCTV systems.

Sequential Video Switchers - Let the switcher take the strain. Take time out to automatically select those vital images..

Programmable Video Switchers - Time to get clever; see what you want, when you want.

Alarm input switchers - Never get caught out watching the wrong picture at the wrong time; alarm inputs can help.

Multiple output switchers - sending pictures all over the shop, is kids stuff for these highly flexible bits of equipment.

The video switching ‘matrix’ - The ‘Big Daddy’ of all switchers. Almost infinitely expandable modular routing systems.

Ten ‘must know’ things about Switchers - Okay we all know they switch, but how many other key points can you think of?

How to get the best from a switcher - Time to think laterally. Many applications rely heavily on this basic technology.
