28 SECURITY TECHNOLOGY EXECUTIVE • May/June 2015 www.SecurityInfoWatch.com solutions and cyber security seem to be big trends in the VMS/NVR space. The first two are enablers for an enhanced user experience, while cyber security demand is being driven by many different vertical markets such as government, large and multinational cor- porations and the financial sector. Solution manufacturers are also continuing to under- stand the importance of the operator's user experience. STE: What are the market sweet spots for UltraHD, 4K and other extremely high-definition products and what do you see as the future progression of deployment costs of those systems? Willem Ryan: Avigilon recently introduced the security industr y 's first 7K (30 mega- pixel) camera to the market. This camera is most effective in applications such as parking lots, airports (both inside at locations such as baggage claims and outside to monitor the perimeter and tarmac), stadiums and critical infrastructure locations such as electric power stations. Future development of ultra-high definition products will involve the ability to provide wide area coverage with the simul- taneous ability to zoom in for clear image detail. It is important that these HD products are paired with accompanying software that can manage bandwidth, storage and decoding appropriately. Fredrik Nilsson: 4K is ideal for environ- ments where large areas need to be covered, while still maintaining a high level of detail. 4K products, which were first announced just last year, are for niche applications with wide spread adoption still far off as HDTV 720 and 1080 hold steady as the mainstream resolu- tions. Some of the drawbacks to 4K products are the cost associated with the lenses and the reduced light sensitivity as a result of the smaller pixels which require higher light lev- els to activate. Another drawback to 4K and megapixel cameras is that more image resolu- tion means more data, ultimately requiring more bandwidth. It's important to remember that like HDTV, 4K is a standard that involves much more than just resolution, including color fidelity and frame rate. Megapixel cameras, on the other hand, are not bound by standards. As manufacturers continue to launch cameras with higher and higher resolution, integrators need to weigh the benefits of those technolo- gies against the requirements of the specific scenario to ensure that the system provides the end customer with the quality, level of detail and storage requirements they truly need. Sean Murphy: Cameras that deliver 4K ultra HD resolution should be considered one of the tools in a surveillance toolbox. These cameras are useful for situations where the user needs to be able to digitally zoom into areas of a scene without losing the wider field of view. This level of resolution may not be needed for ever y area of a facility, but it is ideal for covering large areas – such as inside an arena or stadium bowl, transpor tation facility, or large retail store – where identify- ing objects at a great distance is necessar y. 4K ultra HD cameras provide more detailed images with more useful information that improves identification and retrospective analysis capabilities. With more detailed images, the volume of data being transported and stored rises. There is technology available, such as IDNR, which limits the impact on bandwidth con- sumption and storage requirements to lower the costs associated with systems using high resolution products. Christian Morin: Given the higher band- width and storage costs to leverage 4K/ multi-megapixel cameras, they are likely to see greater adoption in applications that will most benefit from the higher resolutions. T his includes outdoor environments with large open spaces, whether on an airport run- way or within a stadium or casino, where the greater field of view can provide the opportu- nity to replace the use of multiple lower-res cameras. Kenneth Hune Petersen: Over time, 4K will become the de-facto standard for cameras in our industry. Right now we see increasing interest for it in high-end segments of the market. Customers interested in 4K deploy- ments typically operate a command or situ- ational awareness center. 4K cameras are interesting due to the unique combination of video over view and zoom-in for detail visibility, both for real-time and post-event investigations.
