CCTV surveillance system is an important part of the security technology prevention system. It is an advanced comprehensive system with strong defense capabilities. It can be directly watched and monitored by remote control cameras and their auxiliary equipment (lenses, PTZ, etc.) All the conditions of the place can be seen at a glance. At the same time, the TV monitoring system can also operate in conjunction with other security technology prevention systems such as anti-theft alarm systems, making its prevention capabilities more powerful.
?? The closed-circuit monitoring system can reflect the picture of the monitored control object in real time, image, and reality in situations where people cannot directly observe, and has become an extremely effective observation tool for people to monitor in modern management. Because it has the unique function that only one person can operate in the control center to observe many areas, even remote areas, it is considered to be a necessary means of security work.
?? Closed-circuit television monitoring system (CCTV) can provide close observation, monitoring and control of some important areas. The system complies with relevant national technical specifications. Generally, a TV camera should be installed in the system to achieve all-round monitoring. The main equipment of the system should be equipped with a TV monitor, a time-lapse video recorder, a picture processor, etc., so that the user can view any picture and remotely operate any gimbal and zoom function with a remote control camera.
?? Choose the appropriate system configuration according to the purpose, CCTV monitoring system can meet your various needs:
??
? Outdoor PTZ: In addition to all the functions of indoor PTZ, it also has waterproof and explosion-proof functions
? Hemispherical color / black and white camera: ceiling mounted, beautiful appearance, suitable for various occasions
? Color monitor: used to display the front end
? Color camera video
?? Time-sequence switching system: The images of multiple cameras are switched and displayed on one monitor in sequence, and the switching screen of the key can be displayed, and the switching time can be adjusted. Even if the number of cameras increases, the monitor does not have to increase, so the system can save costs and is very economical.
?? Digital segmentation system: Divide the screen of one monitor to display the images of 4 to 16 cameras at the same time. Only one person can monitor the scene of multiple locations at the same time. All camera images can be programmed into groups or switched to split display on one high-definition monitor at the same time, and can also be freely switched to select individual display in sequence or set to 4 split or 9 split display status. The key camera images in the system are sent to a 16-frame processor and a 24-hour video recorder uses a box of ordinary 180-minute video tapes to record in real time. The video can be played back to provide evidence for management.
?? Remote operation of the camera zoom system: Pan and tilt pan / tilt color 32x zoom camera, through the operation of the system control keyboard, the camera image can be scanned from top to bottom, left and right, and the camera pan and tilt, lens focal length, lens aperture, etc. Operation, long-distance capture of the panorama of the on-site objects and enlarged details, the magnification can be predetermined.

?? Summary of various lenses: electric zoom lens, automatic iris lens, manual iris lens
?? Digital color camera: with automatic electronic shutter, automatic tracking, white balance, backlight compensation, accurate color reproduction and other functions.
?? The closed-circuit monitoring system can reflect the picture of the monitored control object in real time, image, and reality in situations where people cannot directly observe, and has become an extremely effective observation tool for people to monitor in modern management. Because it has the unique function that only one person can operate in the control center to observe many areas, even remote areas, it is considered to be a necessary means of security work. Therefore, the closed-circuit television monitoring system plays a unique role in modern architecture. The meaning of closed-circuit monitoring is not limited to the supervision and management of various bank center staff and storage warehouses in a commercial center. Its use is still quite extensive. For example, it is used in the intensive care unit of a hospital to observe the condition of several patients at the same time; it is used in a traffic center to monitor the traffic flow of highways, ports or subways, and to schools to ensure the safety of students' sports. In dangerous environments and in dimly lit conditions, this monitoring can still be performed normally. Closed-circuit television monitoring system (CCTV) can provide close observation, monitoring and control of certain important areas. The system complies with relevant national technical specifications. Generally, a TV camera should be installed in the system to achieve all-round monitoring. The main equipment of the system should be equipped with a TV monitor, a time-lapse video recorder, a picture processor, etc., so that the user can view any picture and remotely operate any gimbal and zoom function with a remote control camera.
?? The closed-circuit monitoring system is mainly composed of the following parts:
?? 1. The camera or imaging device that produces the image;
?? 2. Image transmission and control equipment;
?? 3. Image processing and display equipment. ?
?? The technical requirements of the CCTV monitoring system are mainly: the resolution of the camera, the transmission bandwidth of the system, the signal-to-noise ratio of the video signal, the standard of the TV signal, the function of the camera to achieve higher image quality and operation, and the environment of each device of the system adaptability.
?
? Picture processor:
?? Picture processor, which can display one to sixteen pictures on one monitor at the same time, and record one to sixteen pictures with a video recorder
? Professional video recorder:
?? With 24-hour long-delay recording function, the playback picture is clear
? Video switcher:
?? Automatic video switcher for sequential switching of video signals
?
Protective cover bracket ?? PTZ lens controller
?
Matrix system keyboard matrix system host ?? decoder
