CCTV
CCTV Systems within licensed premises
A correctly designed, installed, and maintained CCTV system can be an effective tool in the prevention and detection of crime in pubs and clubs. It can influence the behaviour of patrons, protect staff & property, and provide evidence in the event of a crime. This document is intended to provide a minimum performance specification for the installation of a CCTV system, or the upgrade of an existing system, within licensed premises on the Isle of Man.
Title: CCTV Systems within Licensed Premises: Operational Requirement Analysis

In its simplest form this Operational Requirement (OR) makes the reader ask a series of simple questions:
Why am I installing a CCTV system?
What do I want it to do?
Where should I install cameras?
How should I record the images?
When a premises contracts a supplier to install a CCTV system, the supplier will need to ask a number of questions to establish the exact requirement. It is unlikely that the client - not being a CCTV professional - will have sufficient technological knowledge to specify exactly what is required.
The use of an OR approach simplifies the process and reduces the opportunities for confusion which may lead to an ineffective and unsatisfactory installation.
The OR should answer the following questions:
Who and/or where is to be observed?
Patrons and staff
Locations within the premises (interior/exterior)
Which activities are of concern?
Incidence of disorder
Assaults
Theft of property
Damage to property
Dealing of drugs
Drug abuse
Suspicious actions
Why are the activities being observed?
To monitor behaviour
To recognise and identify offenders
To produce physical evidence of incidents which may subsequently be used in Court
Picture quality
The quality of images recorded is of paramount importance. They should therefore:
Clearly show actions of persons involved in an incident
Give evidence of identity of offenders
Show an overall view of the scene
Be time and date stamped (preferably referenced to the atomic clock transmitted by NPL from Rugby)
A basic OR covering these points should enable the installer to specify an appropriate system.
This document is intended to help the reader buy an effective system. It provides a checklist of criteria which are required for the specification of a CCTV system. It also provides some technical information that will help the reader to make an informed decision about the detail of picture required, where to site cameras to ensure sufficient picture quality and how to ensure that the lighting is appropriate. The guide also covers data protection concerns, and gives guidance on the storing and sharing of images.
