Problems solved by technology

[0002] With the gradual improvement of modernization, some monitoring systems are more and more used in various places such as public places and residences. In the past, for some monitoring products of power transmission, the voltage of the consumer terminal will increase with the growth of the transmission line and the power. The increase and gradually decrease, the camera and other electrical appliances often cannot work normally because they cannot get a stable working voltage, which limits the transmission distance

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 The network cable shown is the control terminal of the monitoring device that transmits video signals, stable voltage and control signals. The connection port of the control terminal RJ45101 is composed of three parts: differential video signal restoration circuit, camera power input and control signal input.

[0019] The differential video signal in the differential video signal restoration circuit is first sent to the EL5172 chip 104 through the lightning protection electrostatic protection circuit 102 and the impedance matching network 103 circuit, and the analog video signal restored by the EL5172 chip 104 enters the video monitoring platform.

[0020] The control signal input is connected to the RS485 control 106 through the lightning protection electrostatic protection circuit 105 .

[0021] The camera power input is connected to the 24VDC inp...

Abstract

The invention relates to a monitoring device, in particular to a monitoring device using a net wire to transmit video signals, stabilized voltage and control signals. The monitoring device comprises a camera end and a control end, wherein the camera end is connected with a connecting port RJ45; the control end is at least connected with a connecting port RJ45; and the connecting port RJ45 is connected with the connecting port RJ45 through the net wire. Compared with the prior art, the monitoring device using the net wire to transmit the video signals, the stabilized voltage and the control signals can solve problems which can be solved only by a plurality of lines by only one eight-core unshielded twisted-pair net wire, so that a great number of coaxial cables for transmission, power supply transmission cables, control wires and the like can be saved, the cost is greatly saved, and the monitoring device is more convenient to maintain in the later period.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device which uses network cables to transmit video signals, stable voltages and control signals. Background technique [0002] With the gradual improvement of modernization, some monitoring systems are more and more used in various places such as public places and residences. In the past, some monitoring products for transmission power supply, the voltage of the consumer terminal will increase with the growth of the transmission line and the power. The increase of the voltage gradually decreases, and the camera and other electrical appliances often cannot work normally because they cannot obtain a stable working voltage, which limits the transmission distance. At the same time, cameras need to be installed in security, monitoring, and school automatic recording and broadcasting projects. A project often needs to install multiple cameras. The existing solution is to separate the...
