May/June 2015 • SECURITY TECHNOLOGY EXECUTIVE 29 www.SecurityInfoWatch.com Bob Banerjee: High-resolution cameras will probably replace a por- tion of PTZ cameras, especially unmanned PTZs, because they can see and record the same field of view, even when they digitally zoom into an area of interest. They're also a solid-state solution, which trans- lates into reliability, physical size, and power consumption benefits. However, PTZs benefit from greater image quality during optical zoom and less distortion since the field of view is narrower. Higher resolution cameras demand more bandwidth and storage, but since HD storage and processing costs are decreasing, cost probably won't be a factor. For these reasons, we expect 4K and very high-resolution imagers to steal some market share from moving cameras, but we don't expect them to entirely replace PTZs in the near future. Johnathan Lewit: Today, these products are attracting some inter- est from early adopters. They will become mainstream when they are capable of delivering the image quality demanded by security appli- cations – specifically when low light and WDR performance of 4K sensors approaches that of HD Sensors today. Further, the high band- width and storage requirements of 4K cameras cry out for solutions in compression. When a critical mass of cameras and VMSs deploy technologies such as h.265 that can substantially reduce storage costs for customers, 4K cameras deliver on their promise of more detail in security video at a reasonable total cost. With all the interest in increasing the density/resolution of video data, Video Management Systems will focus more on helping to man- age the load this content puts on the information backbone, the net- work. Complex streaming algorithms will leverage the latest standards to most efficiently utilize bandwidth, storage and patience. Tom Cook: Eventual adoption will be in outdoor parking lots, as replacements of PTZs for long range detail views and large cover- age. Most end user try this with 2MP, and 3MP and find they are not adequate to support the full parking areas from where the cameras are mounted and to see detail license plates when necessary from the same camera views. The cost of this system is about 25 percent high- er, but if it resolves the issue the end user will migrate quickly to this technology. Allen Chan: The benefits of 4K and beyond will prove invaluable for outdoor city surveillance and transportation markets such as air- port, railway, stadium entrances or the like, where large coverage is essential for situational awareness, but at the same time details can be shown when required. However, 4K is not the only answer for all applications. It is the combination with HD and FHD systems that can delivery cost efficiencies. Jammy DeSousa: Multi-sensor cameras seem to be hot in the cam- era space. Multi-mega pixel cameras are now commonplace for indoor applications but higher pixel count camera offer excellent options for outdoor or large indoor applications like stadiums or city surveil- lance. Camera technology, however, is once again ahead of viewing and recording technology – for example most standard monitors are not able to take advantage of the additional pixels offered by 4K. Once 4K capable monitors and other surveillance products become main- stream that will help to drive overall adoption. ■ 800-729-3839 830-629-2900 www.detex.com Security Swing Door System S D Hands-free, reliable access to restricted areas.
