VIDEO SURVEILLANCE TRENDS & TECHNOLOGIES By Frank De Fina Megapixel Drives the Market Once considered niche products, HD cameras are changing the way integrators deploy surveillance solutions I am frequently asked by our customers, staff and reseller partners: "Which technology is driving advanced video surveillance solutions?" If you had asked me this question a year ago, I would have most likely replied, "It's IP networked systems, of course," but that answer needs to be footnoted these days, as it is not the network itself that's pixel cameras; in fact, H.264 compression is up to ten times more efficient than motion JPEG when calculating bandwidth and storage requirements, which makes megapixel cameras a highly efficient means of capturing high resolution images. Further exploiting the bandwidth efficiency of H.264 compression, Samsung's engineering team has developed a new algorithm that keeps bandwidth at 2.5MB on a 2 megapixel camera, where many 2 megapixel cameras typically demand as much as 8MB of bandwidth. But even with such quantum leaps in bandwidth efficiency and overall imaging performance, the education process to convince resellers and end-users on the benefits of megapixel imaging has taken some time to change old perceptions. Fortunately, the industry has turned that corner as megapixel cameras continue to deliver proof of performance for numerous applications around the globe. More Features, Shapes and Sizes Single sensor panoramic cameras' viewing modes include single panorama (one 360° image), double panorama (two 180° images), quad (four 90° images, as shown), or a single rectangle (one 180° image). 28 changing the landscape of video surveillance — it is the IP devices that we are hanging on these networks. Among the most notable and influential of these are megapixel cameras. A few years ago, megapixel cameras were widely considered niche products for specialized applications — as they were bandwidthhungry devices that typically required dedicated networks and lots of server space for storage. The adoption of H.264 compression truly changed users' perceptions of mega- In addition to megapixel cameras becoming much more network friendly, they have also benefitted from numerous feature enhancements. Megapixel cameras are now available in many different form factors for various uses within a video surveillance system, making them more practical for mainstream applications vs. conventional IP cameras. Megapixel cameras are now available with a host of features that not only enhance their performance, but also deliver more functionality. Notable features now available in megapixel cameras include: www.SecurityInfoWatch.com | SD&I; | January 2014
