The British Security Industry Association’s (BSIA) dedicated CCTV Section has welcomed the revision of British Standard BS 8418, claiming that the changes will make it easier for security installers and monitoring companies to comply with the standard without reducing system effectiveness.
A Code of Practice covering the installation and remote monitoring of detector-activated CCTV systems, BS 8418 was first launched in 2003 with the aim of raising the standard of installation and operation of integrated systems. However, following its review in 2010, compliance with the standard had proven difficult for many due to the complex technical requirements it includes. The British Standards Institution (BSI) has now taken steps to rectify this situation in the latest revisions to the document.
Talking about the 2010 standard, Simon Adcock (chairman of the BSIA’s CCTV Section) commented: “The aim of the 2010 standard was to further raise the bar in system quality but it had the effect of reducing the adoption of the standard. A standard that’s impractical to implement impacts negatively on the average installation quality, on the industry and on end users so a further review was wholly justified. Members of the BSIA’s CCTV Section led the review, the brief being to simplify the requirements and maintain effectiveness but also to ensure that end users would have a clear understanding of what was and wasn’t included in their systems.”
David Wilkinson, director of technical services at the BSIA, added: “The overarching reason for the review of BS 8418 was to make the standard more achievable by removing some of the onerous technical requirements and simplifying the structure of the standard. To date, the BSIA has been heavily involved in the development of this Code of Practice through its work with the BSI, enabling our members to adequately prepare for the forthcoming changes and incorporate them into bids for new business.”
Visual confirmation of developing scenarios
When deployed, BS 8418-compliant solutions consist of cameras and detectors placed strategically around a site, linked together by specialised transmission equipment to a Remote Video Response Centre (RVRC). Here, operators can visually confirm what’s happening, call up on-screen plans of the site and communicate warnings to intruders via on-site speakers.
If necessary, the RVRC operators can also alert the police service who, as the incident is confirmed visually and is associated with a URN (Unique Reference Number), should provide a rapid response.
The principal changes to BS8 418 as implemented in the latest revision include the following:
*Improve the document structure to better reflect the responsibilities of the installer, maintainer and RVRC
*The need to carry out a threat assessment and risk analysis and produce an Operational Requirement document to reflect the requirements of BS IEC 62676-4 has been included
*Clarification of the use of portable/mobile systems within the standard
*Relaxation of some of the tamper recommendations and the inclusion of a tamper protection/indication table to add clarity to the requirements
*Inclusion of a fault recognition/indication table to provide clarity to the recommendations
*A decrease in the number of event memory recommendations
*The need for a UPS is now determined by threat analysis and risk assessment
*Highlighted the need for a minimum of one data transmission path
