Mellon Security supplies/installs/maintains CCTV systems.
CCTV (Closed Circuit TV) is the use of video cameras for surveillance of an area. The image captured by the video cameras can be recorded to a storage medium. This storage medium used to be a time lapse VCR. Nowadays most CCTV systems record and store digital video and images to a DVR (Digital Video Recorder). In the case of IP cameras, the signal is sent directly to a server.
