Why Install CCTV?

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.
