Closer Circuit Television (CCTV)

CCTV stands for Closed Circuit Television. The reason why it is called Closed Circuit, is that the signal is not available for Public Broadcast. CCTV systems are primarily used for security reasons but clients also use them to monitor staff and production lines. The water mark that is produced on every event recorded allows companies to use this as evidence in a court of law.

IP-CCTV is a fully digital method of capturing, transmitting, and recording video data. IP stands for Internet Protocol, but IP-CCTV has nothing to do with the Internet, well at least until cameras and Network Video Recorders (NVR’s) are connected to the internet.applications.


HDCVI cameras offer up to 4 megapixel recording resolution (2560×1440) but are installed using standard coax cable. This means if you have an existing analogue CCTV system the HDCVI cameras can simply replace your old analogue cameras.
