What is CCTV?
CCTV stands for 'closed circuit TV which relates to the use of video cameras to transmit or 'stream' video / images to a specific location e.g. to your computer screen or to a set of monitors. Costs of CCTV have come down dramatically in recent years making CCTV a convenient and effective method of increasing security and deterring criminal activity.

GTR provide a variety of CCTV systems, from the most basic camera system, comprising of a static camera connected to one monitoring position, up to a multi-camera / multi-site system, with programmable alarm zones utilising the latest industry standard hard drive recording equipment and full network streaming for worldwide access. In terms of storage rather than the video tapes that used to be used now hard disks tend to be favoured and the quality of the digital recordings, aside being dependent on the lens etc being used, are dependent on the compression ratios used, image size, duration of video being recorded and the number of images (i.e. 'frames') stored per second.
