Remote feed video monitoring system based on four wires

Abstract

The invention discloses a remote feed video monitoring system based on four wires. The system consists of a local side, a terminal and a twisted-pair system for connecting the local side and the terminal, wherein local side equipment has an intelligent power supply function; and feed voltage is transmitted to terminal monitoring equipment through twisted pairs. The remote feed video monitoring system is characterized in that the two groups of twisted pairs are used for connecting the local side and the terminal, wherein one group of twisted pairs is used for video signal transmission; the other group of twisted pairs is used for feed and control signal transmission. Firstly, a control circuit is activated through feed voltage polarity transformation, and then camera transmission or tripod head startup actions are performed under the action of a control instruction. The remote feeder video monitoring system has the benefits that a method for awakening the terminal monitoring equipment is simple and easy to realize, the arrangement of the wires is simple, the feed efficiency is high and the power is high.

Description

technical field [0001] The invention belongs to a method and a system for controlling the operation of a remote video monitoring device, in particular to a method and a system for waking up the monitoring device by using two sets of twisted pair wires. Background technique [0002] The focus of this patent is to use twisted pair to wake up the remote monitoring equipment, and the most common case of twisted pair to connect the remote equipment is the fixed telephone system. We know that ordinary landline phones can work with only one network cable. That is to say, the telephone system has the ability to wake up and monitor status remotely, and the central office equipment can remotely wake up the terminal equipment and receive terminal information, such as sound and image. [0003] The remote power supply implementation method of ordinary fixed telephone system is as follows figure 1 shown. In the figure, module 1 represents the central office power supply system, module 2...

AI Technical Summary

Problems solved by technology

[0006] The traditional telephone system uses 90V AC ringing current, and the power supply system conflicts with the ringing current system. The system structure is complicated, the power consumption is high and the cost is high, and it is not suitable for remote and harsh environments. It should be cancelled.

[0007] In addition, most of the monitoring devices currently on the market are placed in smart homes, urban roads, warehouses, and office spaces. These devices can only be turned on and off manually, or are always powered on, and cannot be remotely controlled.
