WIFI OUTDOOR CCTV CAMERA WITH APP CONTROL
The closed-circuit monitoring system provides remote monitoring and control. According to the relevant national technical specifications, the system should be equipped with security cameras, TV monitors, video recorders (or hard disk recorders) and image processors, so that users can watch any picture at any time and operate any camera remotely.
Closed circuit monitoring system is generally composed of three parts: front-end equipment, transmission part and back-end equipment (including control equipment and display equipment).
The main components of the closed-circuit monitoring system are: camera or imaging device to collect images, image transmission and control equipment, image processing and display equipment. The technical requirements of CCTV monitoring system include: the definition 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 picture quality and operation, and the environmental adaptability of each part of the system.
Office building closed-circuit monitoring system scheme, building closed-circuit monitoring system scheme, building closed-circuit monitoring system scheme, most of the closed-circuit monitoring systems widely used in various industries in China are analog mode.
Its main features are: the system adopts matrix host control, monitors the front-end target through the TV wall, and uses long delay analog video recorder for recording and playback;
Its main disadvantages: when the video data need to be backed up for a long time, it needs a large number of video tapes, consumes a lot of manpower and material resources, and is not convenient to operate in video playback retrieval. Therefore, after several years of development, the technology of hard disk video recording system based on digital storage technology has been fully mature, which solves the technical problems of traditional image storage and playback.
Digital hard disk video recording system not only has low storage cost and high efficiency, but also has the advantages of network transmission, remote transmission and cyclic storage. At the same time, advanced technologies such as digitization and transmission networking of hard disk video recording system can realize networking linkage with anti-theft alarm system, timely and accurate feedback of on-site information, and provide sufficient and reliable basis for alarm events.
