solution

The security monitoring system is an independent and complete system that uses optical fibers, coaxial cables, or microwaves to transmit video signals within its closed loop, and from camera to image display and recording, it can reflect the monitored object in real time, vividly, and truthfully. It can replace manual long-term monitoring in harsh environments and record it through a video recorder. Video surveillance&control system (VSCS) refers to an electronic system or network that utilizes video detection technology to monitor fortified areas and display and record on-site images in real time.

It mainly includes four parts: front-end equipment, transmission equipment, processing/control equipment, and recording/display equipment.
