Despite analogue retaining a surprisingly strong hold, the technology behind video surveillance is moving to HDCCTV, hybrid and IP technology. CCTV Image takes the surveillance sector’s tempera- ture, finding out how councils and other public sector bodies are coping in these challenging times.

IT’S INSTRUCTIVE to reflect that, 13 years into the 21st century, analogue video surveillance equipment should still be dominant. Yet, as market research and consultancy IMS Research (recently acquired by HIS), revealed late last year, analogue cameras account for 87% of total camera shipments. What?! Wasn’t Britain the CCTV pioneer? How can this still be true? To puncture your incredulity, this is analogue’s share of the consum-


er and DIY video surveillance market, where high price sensitivity is one reason why a significant revenue transition to network surveillance is not predicted in the next five years either. Of course, the professional market is a different ball game, yet even here some sectors are still relatively slow to adopt hybrid, HD or IP technologies. In the gaming industry, for example, the last remaining VCRs were


only removed from a UK casino just over a year ago, when Visimetrics replaced units in December 2011. Many venues are still routinely using other analogue technology, such as cameras and video matrices (CCTV Image, Autumn 2012). The surveillance demands of these venues, combined with the cost and perceived lack of credible technological alternatives are some of the reasons for this conservatism.


HDCCTV traction Indeed, analogue is still said to account for the majority of small to


medium sized (eg 4-16 camera) commercial installations, since accord- ing to its proponents the technology offers advantages including lower cost and greater flexibility of design when compared with IP, for exam- ple. With IP being more generally recognised as an applicable solution for new-build and larger installations, HDCCTV has gained traction in the UK over the past few years as an opportunity to digitally upgrade existing analogue systems and cost-effectively extend the operational life of coax cabling.

CCTV over IP HD-SDI


Maintenance Savings


In these financially constrained times within the public sector, it’s tempting to rely on the horizontal line resolution of analogue cameras, which has risen to around 540-570HTVL and been boosted by other improvements including reductions in chip noise, digital noise reduc- tion, better lenses and specific technologies such as Pixim that help make these cameras more useful across a range of difficult lighting conditions. HDCCTV, on the other hand, delivers high-speed serial digital


data over a variety of cabling formats and the stream is converted into H.264 format. Since this is a common compression standard for most DVRs, NVRs and network cameras, it means analogue, network and HDCCTV cameras can all be plugged into the same tri-format hybrid DVR. The HDCCTV Alliance, formed just four years ago in May 2009,
