This product is an encryption and decryption module designed for analog video signal mission equipment, to provide users with efficient and secure video mission solutions. The module adopts advanced encryption algorithms and can encrypt analog video signals in real time to that the video content is not stolen or tampered with during mission. At the same time, the device supports real-time decryption to that authorized users can seamlessly receive and watch the original video content. This product is equipped with two modules, video encryption and decryption, which are connected to the mitter and receiver of analog video signals respectively. The encryption algorithm effectively prevents illegal interception during video signal mission and ensures the security of video data.
