Problems solved by technology

However, for long-distance transmission, additional IP network support is also required, and there are also problems of complex system equipment and management
In addition, the code stream of high-definition IP cameras is much higher than that of ordinary IP cameras, which can easily cause IP network congestion, which also greatly limits the large-scale popularization and application of high-definition IP cameras.

Abstract

The invention relates to an EPON video camera adopting EPON optical fiber communication technology, comprising a camera lens, an image sensor module and a controller. The EPON video camera is structurally characterized by further comprising a video compression encoding module, an EPON ONU module and an analog / digital (A / D) video output interface module, wherein the video compression encoding module is used for compressing and encoding original image obtained by the image sensor module as well as encapsulating the original image into IP package signals; the EPON ONU module is used for receiving the IP package signals sent out by the video compression encoding module and completing optical fiber access of EPON; the analog / digital video output interface module is used for A / D conversion for the original image obtained by the image sensor module as well as outputting A / D image signals. The EPON video camera can meet the requirements of long-distance networking transmission and control of the large-scale video cameras, and not only has the functions of collecting and outputting image, but also the function of transmitting the image within a long distance by an optical fiber.

Description

technical field [0001] The invention relates to a camera for video monitoring, in particular to an EPON camera using EPON optical fiber communication 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, it is necessary to install additional transmission equipment behind the cameras, resulting in complex system equipment and management. . [0004] Common-definition IP cameras have a built-in video compression module, and output IP signals through RJ45 and use twisted-pair cables to connect to Ethernet for transmission. However, this kind of camera r...
