Enterprises Monitoring System
　　The entire monitoring system is divided into front-end camera, transmission link, control room control / display device of three parts.
   
   　　Camera section: the role of the system being monitored target light, sound signals into electrical signals and fed into the transmission system to transmit the allocated portion, the core part of the camera is a camera, it is a front-end image information for data acquisition, and the main equipment photoelectric signal conversion, the entire closed-circuit television monitoring system of the eye, the difference between the number of lines of image resolution analog cameras in general is, the higher the thread count the more clearly the difference between the number of megapixels to clear the image is a digital camera degree, the higher the pixel ultra-clear picture. Camera power supply into a centralized power supply and on-site to take power, longer lines generally use the site to take power, close the general approach to a centralized power supply to take power.
   
   　　Transmission parts: the role of the video signal is sent to the central office or other monitoring points. Closed-circuit television monitoring system allocated for transmission of video signals commonly used in so-called baseband transmission itself, sometimes with carrier transmission or pulse-code transmission, the system uses cable transmission medium of communication are used baseband transmission. They are: feeder, video distributor, video cable compensation, video amplifiers and other components. Analog control system line more than 200 meters, single-mode optical fiber transmission, can pass through a single mode optical transceiver can transmit 32 images, network monitoring system will be carried out over 90 meters with fiber optic transceivers photoelectric conversion to an optical signal transmitted through the optical fiber to the host when NVR through photoelectric conversion into digital signals, digital monitoring system than the analog system should be clear image, but also the direction of future development of the monitoring system.
   　　Control room monitor / display equipment: refers to an image signal transmission system for recording, processing, playback and copy functions, the display effect is to use part of the monitor image reproduction. Control room control equipment items include basic video matrix control, flat screen monitors, full real-time digital video recorders. In addition, depending on the needs, but also increase high-resolution flat-screen TV wall, projection equipment, signal encoder.

   Family and shop monitoring system
　　Installation via cable distribution network lens can monitor remote computers and mobile phones, you can also install a wireless camera, if the wiring is not convenient, you can store and monitor remote computers and mobile phones through a wireless network.
   

   Other monitoring systems
　　Monitoring system also includes an electronic fence, infrared alarm system.

   　　Is the most advanced electronic fence perimeter anti-theft alarm system, the system consists of an electronic fence host front-end accessories two major components. Typically, the host electronic fence outside, along the existing wall (eg brick walls, concrete wall or fence) installed pulse hosts also usually outdoors, by signal transmission equipment to alarm signals to the rear end of the control center.
   　　Electronic fence blocking effect is reflected in the deterrence function, metal line suspension warning signs, saw psychological pressure, feeling and touching the fence electric shock, enough to discourage intruders so; secondly electronic fence is itself physical barriers, install the proper height and angle, it is difficult climb; if force a breakthrough, the host will issue a warning signal.
   　　Electronic fence its unique properties, is widely used in substations, power plants, water plants, factories, industrial powerhouse, industrial and mining enterprises, materials warehouse, residential quarters, villas, schools, airports, aquaculture and livestock premises, government agencies, focusing on Heritage sites, military facilities, prisons, detention centers, which are walls and walls of the place needs.
