environment design In regards to the perception of security in active operation, the most common image that comes to mind for most people is possibly a security officer monitoring a CCTV camera feed. While the use of cameras by patrol watchmen is not as ubiquitous as the popular image implies, it is still a highly cost effective form of detection that is a part of many physical protection plans and enhances the effective range of a security officer.
One of the most important factors in its success is the location the camera is placed at. A camera needs to be pointed at an occurrence of interest, whatever that may be, in order to be of use beyond deterrence. One way to cover the most activity is to monitor entry points as part of an access control program. Covering main entrances or stairwells can ensure all persons who enter a property will pass under a camera at some point. Automatic entry systems can be monitored to ensure no unauthorized entries are made, including at vehicle gates.
The deterrence value of a camera system should also not be forgotten. Having a visible camera can stop many acts of crime, theft, or vandalism that may have proceeded if the potential criminal did not believe they were being actively watched or recorded. When coupled with good lighting and environment design, cameras can be one of the most effective important tools in a protection plan.
