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.

What about the current use of CCTV in Town Centres ...? - continued -

This is particularly essential in the fight against terrorism, where by the nature of the attacks, it's almost impossible to identify, much less deter a concerted terrorist. Evidential quality recording could provide the key to unlocking a terrorist cell; after all, you may not see a terrorist coming, but you'll almost certainly be aware of where they’ve been.

Town Centre systems comprised almost entirely of remote control cameras, will hardly if ever be able to fulfil the requirements for even the most basic Passive Evidential Quality Recording (PEQR).

As you’ve probably gathered by now, it’s unfortunate that the design of so many Town Centre CCTV schemes has been intrinsically flawed from the outset.
Remote control cameras are a technical enhancement, which ideally should supplement an existing array of dedicated fixed view cameras, and not naively be regarded as an alternative.

What has happened historically, is that system designers (and their clients) have gone for the most simplistic approach of achieving the greatest potential area of visual coverage, using the least amount of imaging equipment (PTZ or fully functional Dome cameras).

Doktor Jon tends to have a somewhat more objective approach to system design:-

"When developing a CCTV system profile, those areas identified as key locations should be constantly monitored by dedicated fixed high resolution cameras, in order to adequately fulfil the objectives for Passive Evidential Quality Recording (PEQR)".

Only when these key cameras have been correctly profiled, should attention then turn to the appropropriate locations for (active) remote control PTZ or Dome type units, which may specifically be used for tracking and identifying suspects.

In existing Control Rooms. greater emphasis sometimes needs to be placed on the way in which available camera images are presented to the Operator, in order to achieve maximum efficiency.
