How Cisco IT Deploys Closed-Circuit TV Cameras Over the Secure IP Network

Cisco uses video surveillance to help keep its work environment secure. Two years ago, Cisco used a combination of cameras and Video Cassette Recorders (VCRs) to monitor building entrances and other high-security locations on its campuses. Managing the VCRs, coaxial cabling, and tapes was labor intensive and prone to human error. Looking for a better solution, Cisco implemented Closed-Circuit TV (CCTV) over IP for surveillance. The system uses digital video and uses IP to carry the video signal across the network to digital video recorders in a centrally managed data center. Since making the change, Cisco has improved security, enhanced building access control, and significantly reduced security costs.
