The monitoring system consists of five parts: camera, transmission, control, display and recording. The camera transmits the video image to the control host through the coaxial video cable, and the control host then distributes the video signal to the monitor and video recording equipment, and simultaneously records the voice signal to be transmitted to the video recorder. By controlling the host, the operator can give instructions to control the up, down, left and right movement of the pan/tilt and zoom lens, and can switch between the multi-channel camera and the pan/tilt by controlling the host. Using special video processing mode, images can be input, played back and processed, so as to achieve the best video recording effect.
principle of operation
Monitoring is the physical basis for real-time monitoring of key departments or important places in various industries. The management department can obtain effective data, images or sound information through it, monitor and remember the process of sudden abnormal events in time, thus providing efficient and timely command and height, deploying police force and handling cases. With the rapid development and popularization of computer applications, a powerful digital wave has been set off around the world, and the digitalization of various devices has become the primary goal of security protection. The performance characteristics of digital monitoring alarm include: real-time display of monitoring picture, single channel adjustment function of video quality, independent setting of each video speed, quick retrieval, multi-video mode setting function, automatic backup, pan/tilt/lens control function, network transmission and so on.
Add a time generator to superimpose the time display on the image. When the line is long, install audio and video amplifiers to ensure the quality of audio and video monitoring. Scope of application-banks, securities business places, enterprises and institutions, institutions, commercial places, building passages, parking lots, high-end community families, libraries, hospitals and parks.
