Welcome to the
Doktor Jon does his bit to help
Having seen how the objectives for a key component (such as a camera) can be quantified, it makes it much easier to identify what type of equipment should ideally be used, and also where to use it.
Deterrence and Evidential Recording are essentially passive functions of a CCTV system; that is to say, in most situations they do not require the input or control of an operator, in order to be highly effective.
If you think about the installation of a 'Dome' type camera, perhaps in a Town Centre, there is no suggestion as to which way it is looking, and indeed whether an operator is even bothering to monitor the image.
With public area CCTV, positive publicity through the Press and media can very often suggest a far greater enhanced deterrent effect, than the mere presence of the CCTV installation itself. Using a regular feed of success stories to maintain a positive perception of a systems performance, is a highly effective crime reduction technique which Doktor Jon describes as 'DtD' or "Deterrence through Detection".
Whilst we've looked briefly at the 'passive' aspects of DICE, Incident Monitoring and Site Management generally require the efforts of an operator to be successful, and for this reason, these operations are normally regarded as being active functions.
That's the main reason why Town Centre camera schemes are so expensive, and frequently less than efficient when it comes to reducing crime.
A DISE assessment comprises of two 'passive' functions, namely Deterrence and Evidential Recording, neither of which need rely on the input from an operator. Fixed optimised cameras can generally be used in most situations, more efficiently than remote control units.
The 'active' functions are Site Management and Incident Monitoring, both of which normally require the services of an experienced operator, in order to produce results.
