Example Embodiment

[0019] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0020] Such as figure 1 As shown, the traditional camera signal transmission adopts a coaxial cable or a shielded cable to transmit the analog video signal from the remote camera 5 to the video server 2. Each camera 5 is equipped with an independent signal transmission line 6 and a power supply wiring 4.

[0021] The present invention improves the traditional wiring method, such as figure 2 As shown, a conversion device 8 is added at the end close to the server 2 in the control center 1. Connect the analog video interface and power supply 3 of the video server 2 to one end of the conversion device 8, and then connect the network cable 7 to the other end of the conversion device 8 to make The analog video signal and power supply are combined and transmitted through the network cable 7; then a similar conversion device 8 is added to the end close to the camera 5. T...

Abstract

The invention discloses a method and equipment for transmitting analog video signal and realizing long-distance power supply by network cables. An analog signal transmission line is combined with a power cord so that analog signals and a power source can be transmitted together. The main technical scheme includes: adding two conversion devices between a video server and a far-end camera, and connecting the conversion equipment with the video server and the distant camera by the network cables, transmitting the analog video and audio signals and the power source which are combined by the conversion equipment at one end through the network cables, and then separating the analog video and audio signals from the power source by the conversion equipment at the other end. The method and equipment for transmitting analog video signal and realizing long-distance power supply by the network cables solve the problem of complicated assembling of the analog camera, realize the distant power supply and greatly save the material cost and construction cost.

Description

technical field [0001] The invention relates to the field of electronic communication, especially the technical field of analog video signal transmission. Background technique [0002] In the security system, multiple cameras need to be set up in different locations, and then the video signals sent by the cameras are sent to the control center for real-time monitoring and video recording. [0003] At present, the security equipment market is mainly based on analog cameras, and the analog video signals sent by the cameras are generally transmitted with coaxial cables or shielded wires. During specific construction, it is necessary to lay a coaxial cable or shielded wire for each camera, and also provide power for each camera. Due to the different topography and landforms where the cameras are installed, especially for outdoor cameras, such as in downtown areas where underground facilities criss-cross, or in remote areas that are inaccessible, the wiring of camera video sign...
