As the shoppers or ‘guests’ (as retailers prefer to call them) enter the main door, this is generally the first opportunity to obtain optimised Evidential Quality Recordings of each and every visitor, under controlled lighting and environmental conditions.

The shoppers will also be made aware of the presence of CCTV using highly visible signage, and so the deterrent message is stated and demonstrated very publicly, at the main point of entry.

In terms of actual Incident Monitoring, the chances of spotting something are relatively low, unless a known individual is being tracked, either by a security camera Operator, or else using a computer based AFRS (Automatic Facial Recognition System ).

That said, it’s far more likely that in this role, the camera and video analytic system will simply be used to confirm that a target or suspect has left or is about to leave the building.

As a Site Management tool, the most likely objective would be to provide visual verification of any obvious problems with the flow of pedestrians into or out of the centre; something which is particularly important during a controlled evacuation.

It could of course also be used for a variety of other functions, for example, visual verification following a fire alarm activation, cash in transit monitoring through the building, and evaluating shopper behaviour in a retail environment.

Taking account of all these factors, the overiding requirement would be for Evidential Quality Recording, and so the very highest performance fixed colour camera(s) would be strategically placed to fulfil this key role.

In the control room, it’s advisable that this and other ‘guest’ entrance / exit points should be constantly monitored on a dedicated monitor with a split screen display.

Taking each individual door in isolation, the ‘micro’ profiles will differ depending on the perceived degree of risk, so taking the 'Public' entrance as the first example, the "DISE" assessment may look something like this:-

- The Main 'Public' Entrance Door -

Deterrence 10% Incident Monitoring

Site Management 40% Evidential Recording
