Bandwidth-hungry surveillance video running over an existing structured cabling network can result in ongoing organizational contention. Here's how to find a satisfying resolution for all concerned. A new generation of IP (Internet Protocol) CCTV technology is appearing onLAN networks that allow several people to view security cameras through a simple click on a computer, or to access a camera that could be across the street or across the country. But as CCTV IP-based cameras—especially high-definition mega-pixel cameras—become more sophisticated, they also bring on new challenges to security and IT managers.
When selecting a camera, keep in mind picture quality, low-light operation, motion picture, reliability, and impact on network performance. Pictured here is one of JVC's newest outdoor, weather resistant, vandal-proof, IP66-rated IP surveillance cameras. It features a 36x optical zoom and direct-drive mechanism that provides fast and accurate PTZ, as well as an image stabilizer for clear visibility.
One of the biggest advantages of an IP-based CCTV system is the ability to use the existing data and voice structured cabling network infrastructure rather than separate coaxial cable. Previous proprietary analog systems over coax were kept separate from the data and voice network with their own horizontal and backbone system. For IT managers, however, one of the biggest disadvantages of these evolving IP-based CCTV systems is utilizing network bandwidth. Running bandwidth-intensive surveillance video over corporate data networks is a point of on-going organizational contention. Depending on the potential impact on the network performance, one solution is running an IP-based CCTV system on a parallel network, yet sharing the same backbone.
