The invention relates to anti-interference equipment suitable for a network closed circuit television. The anti-interference equipment suitable for the network closed circuit television comprises an equipment box body, and a box cover is arranged on the equipment box body. The anti-interference equipment suitable for the network closed circuit television is characterized in that a signal input terminal is formed in the equipment box body and an input end of a compensation device is connected to the signal input terminal. Meanwhile, an output end of the compensation device is connected to an input end of a video amplification device, an output end of the video amplification device is connected with a signal output terminal, and an energy supplying end of the video amplification device is connected with a power supply device. Therefore, the transmission distance of video data can be extended, interference of various clutters can be avoided, and a good signal to noise resistance ratio is obtained. Meanwhile, capacity of video content can be reduced, and video content transmission requirements of the network closed circuit television are met. Furthermore, the anti-interference equipment suitable for the network closed circuit television is simple in structure and convenient to produce and popularize.
Description
technical field [0001] The invention relates to an anti-jamming device, in particular to an anti-jamming device suitable for network closed-circuit television. Background technique [0002] With the acceleration of urban digital development, network video players are installed in urban railway stations, bus stations, roads, streets, communities, corridors of commercial buildings, elevators and other places as advertising media. However, due to the limitations of many problems such as geographical environment, equipment performance, and line transmission, as well as the interference of elevators, substations, and large-scale power equipment, etc., it is easy to be interfered during the transmission process, resulting in unsatisfactory signal quality and image display effect. Ideal. Contents of the invention [0003] The object of the present invention is to provide an anti-jamming device suitable for network closed-circuit television in order to solve the above-mentioned p...
