CCTV over IP / CCTV DVR
IP Video systems operate over standard corporate networks. Having everything based around a network allows system wide diagnostics to ensure everything is running smoothly. Every device can be continuously monitored and an alarm is raised if anything fails. As these typically span entire organizations, so can IP Video systems connected to them. As the traditional control room equipment can be replaced by a PC it is possible, and often desirable, to be able to monitor live and recorded video from any camera from any point on the network. Each camera is connected to the network via a transmitter/receiver unit that compresses the analogue video into DVD quality MPEG-4 digital video for transmission over the network. The digital video can then be viewed, analyzed and recorded. This is achieved with Windows based PCs running video and alarm management software and Networked Video Recorders (NVRs) that are installed around the network.
