Information transmission system for closed network CCTV

The present invention relates to an information transmission system for closed network CCTV, and more specifically, by connecting a control module that can independently transmit and receive information to and from the outside even in offline places where a network is not installed, to an NVR connected to a CCTV camera and a closed network. This relates to an information transmission system for closed-network CCTV that allows remote monitoring and quick action in the event of a failure or emergency.

CCTV stands for Closed Circuit Television.

It is a system that transmits images from a specific building or facility to a specific recipient using a wired or special wireless transmission path. It has a variety of uses, including industrial, educational, medical, traffic control surveillance, disaster prevention, and internal video information transmission.

Unlike regular television broadcasts, CCTV signals are transmitted only by coaxial cable, microwave link, or other transmission medium with controlled access, so they cannot be arbitrarily received by the general public.

It is often used for unmanned surveillance in crime-ridden areas such as banks or alleys that require security, and is checked by installing a television camera and receiver at a relatively close distance.

Meanwhile, NVR stands for Network Video Recorder and refers to a CCTV recorder that can be used in conjunction with an IP camera.

In other words, NVR is a surveillance device that digitizes the entire camera, video network, recorder, and monitor.
