Technical Operational Requirements Manual

This document includes guidance for organisations who wish to install or upgrade CCTV systems. This guidance concentrates on how to best determine your requirements and ensure that the system meets these as closely as possible.

Digital Imaging Procedure

This is a revision of the Digital Imaging Procedure , first published in 2002. This new version aims to build on the success of the original document and not only reflect current advances in technology, but also look to the future. The principal purpose of the procedure remains the same, i.e. to detail the processes involved in the proper capture and handling of digital images for police applications and to define best working practice

i-LIDS

It is recognised that the workload of today's CCTV operators is increasing and that the full potential of the CCTV scheme in tackling crime may not be achieved. Video Analytics (VA) systems offer a potential solution to the problem of ‘operator overload' by automatically alerting operators in real time to events of interest or identifying sequences of interest to speed up post event analysis.

To help realise this potential the Home Office has developed the Imagery Library for Intelligent Detection Systems (i-LIDS), which aims to stimulate the development of VA systems.

HOSDB Videos

The Home Office's Scientific Development Branch (HOSDB) has produced CCTV Technical Concepts: A Guide to Achieving an Effective System (93/08), a training DVD which is intended to provide non-technical users and those buying CCTV systems with an outline of the key issues. Lasting 45 minutes, it uses graphics, video and narration to help cover a range of topics including field of view, illumination, compression, frame rate and resolution.
