Problems solved by technology

But for high-definition digital cameras, the code stream of compressed video is only about 20M to truly achieve 1080P full HD. The 20M code stream of each video channel directly enters the Ethernet for transmission. When the number of channels exceeds one, the network will immediately be paralyzed
Therefore, the code stream of this type of camera on the market is basically controlled at about 8M, and its definition is difficult to meet the requirements of full HD

Abstract

The invention discloses an optical fiber self-healing looped network camera adopting a network technology of a fiber self-healing looped network. The camera comprises a lens, an image sensor module, a control circuit, a video compressing and encoding module, an optical fiber self-healing looped network module, a video compressing and encoding module and an analog / digital video output interface module, wherein an original image obtained by the image sensor module is compressed and encoded by the video compressing and encoding module and then is packaged into an IP packet signal; the optical fiber self-healing looped network module receives the IP packet signal sent by the video compressing and encoding module and finishes the optical fiber access of the IP packet signal self-healing looped network; and the analog / digital video output interface module performs A / D conversion to the original image obtained by the image sensor module and outputs an analog or digital image signal. The camera can adapt to large-scale, long-distance, high-reliable networking transmission and control requirements of HDV, has a shooting function and has the functions of optical fiber self-healing looped network networking and image transmission.

Description

technical field [0001] The invention relates to a camera for video monitoring, in particular to a fiber optic self-healing ring network camera adopting the optical fiber self-healing ring network technology. Background technique [0002] The existing video surveillance cameras mainly fall into the following categories: ordinary definition analog cameras, ordinary definition IP cameras, high-definition analog cameras, and high-definition digital cameras. [0003] Among them, ordinary analog cameras use video cables to connect with external devices. When long-distance transmission is required, video optical transceivers or video encoders are used for transmission. Therefore, additional transmission equipment needs to be installed behind the cameras, resulting in system equipment and management. complex. [0004] Common-definition IP cameras have a built-in video compression module, and output IP signals through RJ45 into Ethernet for transmission. Although this kind of camer...
