Problems solved by technology

Traditional monitoring systems mainly use coaxial cables for video signal transmission. One coaxial cable can only transmit one video signal, but cannot transmit power at the same time. Additional power lines need to be laid, which not only increases equipment costs, but also increases labor construction costs. Therefore, It is an urgent problem to be solved by those skilled in the art to develop a coaxial cable that transmits both high-definition video signals and power, that is, to combine high-definition video, coaxial and other signals with power supply, and superimpose them on one coaxial cable for transmission.
Some of the existing one-line co-cable transmitters on the market are more interfered by various electromagnetic clutter around them, and the signal attenuation makes the system work poorly

Abstract

The invention discloses a coaxial power supply video transmitter. The coaxial power supply video transmitter comprises a 12V output interface, a video input interface, a power supply separation module, a video signal superposition module and a BNC composite interface, a coaxial cable is used as a transmission medium to transmit a video high-definition signal. An input power supply DC24-36V can stably output 12V voltage to meet the power taking requirement of a camera, power transmission is not needed in the whole process from a machine room to a network terminal, and an analog high-definitionvideo signal and a power supply distance can be extended to 400m by adopting a 75-5 coaxial cable.

Description

technical field [0001] The invention relates to the technical field of communication transmission, in particular to a novel coaxial power video transmitter for power and video signal transmission. Background technique [0002] The continuous development and application of many new technologies and new products have put forward higher requirements for the field of video transmission, especially video transmission and data transmission and monitoring systems in the security and monitoring industries. Traditional monitoring systems mainly use coaxial cables for video signal transmission. One coaxial cable can only transmit one video signal, but cannot transmit power at the same time. Additional power lines need to be laid, which not only increases equipment costs, but also increases labor construction costs. Therefore, It is an urgent problem to be solved by those skilled in the art to develop a coaxial cable that transmits both high-definition video signals and power, that is,...
