Network camera based on power carrier transmission technology

Abstract

The invention relates to a network camera based on a power carrier transmission technology. The network camera based on the power carrier transmission technology comprises a network camera, a communication network and a remote monitoring client, wherein the communication network comprises a modulator-demodulator, a programmable logic controller (PLC) main control terminal and a PLC local side; the PLC main control terminal comprises a main control terminal interface module and a primary coupling circuit; the PLC local side comprises a secondary coupling circuit and a local side communication interface module; a local area network or an INTERNET of a computer is connected with the network camera and the modulator-demodulator; one end of the main control terminal interface module is connected with the modulator-demodulator, and the other end of the main control terminal interface module is connected with a 220V alternating-current power wire through the primary coupling circuit; and oneend of the local side communication interface module is connected with the 220V alternating-current power wire through the secondary coupling circuit, and the other end of the local side communication interface module is connected with the remote monitoring client. According to the network camera based on the power carrier transmission technology, coaxial cables and huge video distributors are not needed, so the engineering cost is greatly reduced; and far-end monitoring is realized by using network resources, so that the defect of monitoring failure caused by halt and restart is also avoided.

Description

technical field [0001] The invention relates to a network camera, in particular to a network camera based on power carrier transmission technology. Background technique [0002] In the prior art, the higher the resolution and ultra-high definition of the high-definition surveillance camera, the bit stream will also increase during data transmission, increasing the pressure on network bandwidth, doubling the data flow, and increasing the recording capacity. On the one hand, it will bring pressure to network storage, and the requirements for central control and management software and hardware performance will increase exponentially. The workload for management and post-event analysis of recorded video images will also increase exponentially, and the investment cost will be high. Contents of the invention [0003] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a network camera based on power carrier transmission t...
