Which Nanchong HD monitor installation works to the good reputation of the installation of monitoring systems is the application of video surveillance, and constitute an independent and complete system from the camera to the image display and recording. It real-time image, a true reflection of the object being monitored, it can be a long time instead of doing surveillance in harsh environments, through a VCR recorded. The introduction of the installation of monitoring systems can be realized on-site monitoring, risk warning, video recording, event traceability and other functions. Installation of monitoring system consists of the following four components: a camera portion imaging section is the leading part of the installation of monitoring system, the whole system "eyes." Place in large monitored area, installation of a zoom lens on a camera, so the camera can observe a distance farther, more clearly; also the camera is mounted on the electric head, you can make the camera pan drive horizontally and rotating the vertical direction, so that the camera can cover a greater angle. Transmission part of the transmission part is to install an image signal path monitoring system. Generally, the transmission section refers to the transmission of a single image, a sound signal. At the same time, the need to have a control center via the console of cameras, lenses, PTZ control, and therefore in a transmission system also includes a control signal transmission. In the transmission mode, the transmission line close to the general use of video, no more than twelve kilometers of distance commonly used coaxial cable transmission, longer distances can use fiber optic transmission. For long-distance transmission, equipped with a video signal amplification needs, the more positive image signal and compensation equipment. Control and part of the control section is responsible for recording and recording of the camera and its accessories (such as lens, PTZ) control, and image recording, the sound signal. DVR technology currently get better, it can not only record images and sound, but also includes a split screen switching, PTZ control and other functions, basically replacing the screen switches used in the past, Quad, PTZ The controller, camera controller, and other products. Display section displays some of the general by a few or several monitors, and currently LCD, plasma, DLP big screen, and other technologies are gradually replacing the traditional CRT monitors. In the number of cameras is not a lot, not very high, the general directly to the monitor connected to the DVR station burglar alarm monitoring system can be. If the number of the camera a lot, and require multiple monitors to complex switching display screen shall be equipped with a "matrix" to achieve. Currently monitoring system with increased levels of development of the computer, the system has been converted to digital from analog systems, digital systems better analog system in function, the operation is extremely intelligent and centralized so on. In the monitoring system installation design, since no more than conventional cameras viewing angle of 90 degrees, so there is always observing traditional cameras each corner, if you need to observe a panoramic scope, it is necessary to complement and coordinate multiple cameras. If you want to use PTZ cameras only shoot it then align and focus the target scene, the stored information of the target scene. The use of a panoramic camera has PTZ functions, it can also observe other scenes in the memory after the image, because the records of the wide-angle lens to capture all the information in the original whole figure. Between multiple cameras while the overall effect observed in a very difficult time with a complete correlation between the respective video images of moving objects from view when a camera is moved to another camera's field of view, monitoring personnel often cause visual confusion because often disappear for a short time the camera view from the junction of the object on the screen, or when the field of vision overlap, the object appears on two screens. The panoramic camera will enable the object remains within its field of view, to monitor staff, better overall observation, can achieve no dead monitor. Note: According to the actual situation and the use of appropriate cameras, such as monitoring hallways, wide-angle surveillance camera does not.
