PTZ Enhancements PTZ cameras continue to be widely used for applications that require real- time tracking of people or vehicles, and have been evolving with new imaging technologies in smaller, faster form factors; however, the continuous movement that PTZs inherently pro- vide consumes more bandwidth than stationary cameras. New 2MP PTZs with H.265 compression deliver the perfect combination of resolution and bandwidth efficiency. ■ » Jennifer Hackenburg is Senior Product Marketing Manager for Dahua Technology USA.

Available in IP and HDCVI config- urations, multi-sensor cameras pro- vide the same coverage typically pro- vided by multiple standard cameras. is reduces overall costs relative to installation, cabling and infrastructure requirements, and maintenance. Multi-sensor cameras are also evolving to incorporate innovative fea- tures and performance. For example, a multi-sensor camera with a built-in PTZ camera is now available – the ultimate integrated imaging solution. ePoE Technology Enhanced Power over Ethernet (ePoE) offers a new way to accomplish long-distance transmission between IP cameras and the network switches at the head-end. ePoE enables more flexible surveillance system design, improves reliability and reduces con- struction and wiring cost. It is best used for surveillance of large venues such as warehouses, parks, campuses, parking facilities, and stadiums and arenas – where camera locations may be required far from the control center. While a conventional approach is to add repeaters to extend the trans- mission distance, ePoE accommodates power and data transmission up to 800 meters over conventional Cat5 Eth- ernet cable. is capability simplifies system installation, as only one cable is required from the system head-end to each camera, which results in lower installation and maintenance costs. In addition, some system designers see ePoE devices as a way to support seamless analog-to-IP migration with long-range transmission. In this sce- nario, they use coaxial cable to inte- grate ePoE IP cameras with Ethernet over Coax (EoC) passive converters for a pure IP solution. is simple and effective solution delivers plug-and- play installation, reducing the cost of upgrading from analog to IP.

Enhanced H.265 compression tech- nologies can provide up to an 80-per- cent reduction in bandwidth and stor- age requirements when compared to standard H.264 compression. Systems employing enhanced H.265 compression schemes reduce band- width usage in several ways by lim- iting the transmission of useless or unimportant data wherever possible. As a result, high-quality video is maintained without putting excessive strain on the network or overloading recording devices. e overall con- servation of bandwidth also enables systems to be more cost-efficiently
