The second-generation analog video encryption/decryption module's indicator light flashes once in encryption mode and twice in decryption mode upon module reset. This module employs advanced encryption algorithms to encrypt analog video signals in real time, ensuring video content is not stolen or tampered with during transmission. Simultaneously, the device supports real-time decryption, ensuring authorized users can seamlessly receive and view original video content. The second-generation product integrates video encryption and decryption functions, connecting to the transmitter and receiver of the analog video signal respectively. The encryption algorithm effectively prevents illegal interception of video signals during transmission, ensuring video data security. The product has been upgraded. The DAC chip packaging has been improved, simplifying the manufacturing process, while other hardware interfaces remain unchanged. On the software side, a significant upgrade has been made, increasing the number of encryption sequences from one to eight, improving communication security. Encryption and decryption functions can now be configured via PC software, allowing users to modify the module's operating mode as needed.
