Video one-way transmission system based on non-feedback light

The invention provides a video one-way transmission system based on non-feedback light, relates to the technical field of information security, and mainly solves the technical problems of invading a security monitoring network and stealing audio and video data through a security camera. The system is composed of a non-controllable external network video monitoring system, a physical optical one-way real-time video transmission system and a controllable internal network video monitoring network which are connected in sequence. The non-controllable external network video monitoring system is used for acquiring field audio and video data in real time; the controllable intranet video monitoring network is arranged at the background and is used for safely storing and analyzing the audio and video data; and the physical light one-way real-time video transmission system is deployed between a camera of the non-controllable external network video monitoring system and a controllable internal network video monitoring n
