PANEL Will resolutions

PANEL Will resolutions rise again? Will the next trend for CCTV manufacturers be a rise in resolution or a continuation of the development of software such as AI, analytics, VMS etc? Is it simply too early to try and move the UK market to 8K? The PSI Panel considers the next move for surveillance developers.... “The introduction of increasing resolutions is an attractive opportunity for manufacturers and their Installers alike” 24 or the last decade or so the resolution of FCCTV cameras has steadily risen to the point where we are recording clearer images than ever before and gathering increasing amounts of video footage data. During the resolution race to 4K we saw manufactures go up through the stages from D1, 720, 960, 2MP, 1080p at pretty much the same speed and launches at trade shows definitely followed a pattern until a few years ago when Avigilon threw a curve ball with a 7K camera announcement. Since then the move to a higher resolution than 4K across the market seems to have taken a back seat in favour of software developments that work with all of the new information being gathered by the latest cameras. Recent trends at the exhibitions have included AI, apps, integration and plenty of analytics capability so does this mean we’re sitting at 4K for a bit longer or will the development of 8K cameras be on the horizon anytime soon? Do we need the 8K TV market to take a more solid footing to create demand? The PSI Panel of experts ponders the immediate trends for surveillance developers. John Goy – CSL The introduction of increasing resolutions is an attractive opportunity for manufacturers and their Installers alike. However, there are other challenges I believe the industry faces that must be considered in any advances that are made. Modern CCTV increasingly sees the CCTV Recording in the Cloud. There are limitations with the Cloud due to bandwidth size, and increased resolution may exacerbate this issue. There is no doubt that higher bandwidth means higher quality but it isn’t that simple. It can take longer for the data to be transferred depending on the connection available. Additionally, if there is no backup connection then data cannot be sent at what may be a crucial time. It doesn’t matter how good the images are if they cannot be sent. This is a major issue for our sector. The need for wireless/4G connectivity is also rising as increasingly sites require a mobile backup, or in fact do not have a permanent wired or IP connection. Now that 4G services are available Installers are provided with better www.psimagazine.co.uk

mobile bandwidth, offering a viable alternative. In fact, upload speeds on 4G often equal those of download speeds as there is less data uploaded from mobile applications. GDPR is also a major concern for CCTV Installers. These connections between the CCTV system and the Cloud must fulfil the GDPR regulations by 25th May 2018. Increased resolution and additional features (e.g. remote maintenance) are attractive but also leave an opportunity for cyber-attacks. Ensuring your system is protected at every stage is vital to protecting your customer and ultimately your business. Stephen D Green – Security Institute Very rarely does technology create demand in the total absence of conscious desire. The Sony Walkman was one notable example of this. Rather, technology commonly develops incrementally to address residual requirements which previous iterations have failed to meet. Mobile phone technology is a good example of such technological evolution in action. The pertinent question here then is whether there exists today any operational impetus towards higher resolutions than are already available. Given that basic offerings from camera manufacturers these days generally provide 1080p, and the market for multimegapixel cameras gravitates towards widearea or long-range crowd surveillance applications often designed around post-event analysis, I see little evidence that commercial or governmental end-users, the majority of whom rely on real-time surveillance, are screaming out for higher resolution. In such post-event investigative environments, CCTV is used generally in support of other broader evidence gathering techniques; it is unusual for a case to rest solely on video evidence alone. Conversely, there does exist a frequentlyvoiced desire to bring greater intelligence and automation to bear on the function of real-time incident management. This demand is driven by the dual aims of curbing costs (by reducing the number of operator hours spent on mundane surveillance) and improving effectiveness (by keeping operator’s fresher for longer and ensuring that nothing is missed). The more the www.psimagazine.co.uk camera and video management system can do to detect anomalous behaviour and present this to operators, the better, rather than relying on them looking in the right direction at the right time. A “Copper’s Nose” is far more effective if it has first been pointed at a target! Thus, whilst markets may be coerced into moving in a specific direction, water will not willingly run uphill. A market will not appear magically for products that are not perceived to serve a meaningful purpose. Tim Biddulph – Hanwha Techwin We appreciate our customers quite often require a solution which enables them to achieve more from their investment in video surveillance in addition to capturing high definition images. At Hanwha Techwin we think there will be a continuing trend in the development of solutions which combine video surveillance with specialist Applications which capitalise on analytics, deep learning and AI. The open platform technology and massive processing power of the chipsets incorporated into the latest generation of cameras means virtually any Application can be uploaded and (continued over) “Whilst markets may be coerced into moving in a specific direction, water will not willingly run uphill. A market will not appear magically for products that are not perceived to serve a meaningful purpose” 25
