The building features 32 floors of business and residential space. The 32-fixed head camera system provides coverage of the building’s entrances and exits, lifts, stairwells, car park and perimeter. Because of the route the camera video transmission method would take, Camsec was reluctant to use a traditional coax transmission method. Mark Horne, regional business development manager at ADI, said: “A number of on-site issues led Camsec to consult with the team at ADI in looking elsewhere for a camera video transmission method. The use of coax would have left the system open to interference problems from these services, adversely affecting the control room’s picture quality, with the resultant spurious interference data soaking-up valuable storage capacity in the digital recorder.”
Horne, in conjunction with Camsec, decided to specify Network Video Technologies’ unshielded twisted pair video transmission technology. It used the NV-208A-M Passive Video Transceiver, with its male BNC allowing direct connection to the camera. Camera video signals are transmitted via Cat5 UTP cable to a NV-3262R 32-channel Active Receiver Hub, located in the on-site security office.
