Video monitoring system and point-to-point wireless link transmission authentication method

The invention provides a video monitoring system and a point-to-point wireless link transmission authentication method, and belongs to the technical field of video monitoring, and the video monitoring system comprises a wireless remote device, a video monitoring device, a wireless base station, a point-to-point wireless device and a central control monitoring station. According to the invention, by establishing the wireless link between the base station and the point-to-point wireless device, videos collected by each video monitoring device can be transmitted back to the central control monitoring station, so that a worker can see the final monitoring video at the central control monitoring station, and the maintenance of power equipment in cold mountainous areas is facilitated. The invention also provides a point-to-point wireless link transmission authentication method, wireless encrypted information is constructed by using the wireless base station, and the wireless encrypted information is sent to the server for authentication, so that multi-aspect security assurance can be provided for the power equipment video image transmitted by the wireless base station, and protection against external threats is realized.
