Video monitoring system and video monitoring method based on optical fiber interface

The invention discloses a video monitoring system and a video monitoring method based on an optical fiber interface. The system comprises a monitoring camera and a monitoring terminal, wherein the monitoring camera is connected with the monitoring terminal by the optical fiber interface; the monitoring camera transmits a non-compressed image to the monitoring terminal; the delay of the monitoring camera is far shorter than that of the existing network monitoring camera; the transmitted non-compressed image is free from image detail loss, thereby facilitating video analysis; an optical fiber communication module is embedded into the monitoring camera, so that the monitoring camera can be used for long-distance transmission; and video compression processing is conducted at the monitoring terminal, thereby facilitating centralized maintenance. The video monitoring system realizes video monitoring.
