FAQ

Q1: How to determine whether the encryption and decryption video board is faulty?

A1: When you turn on the power supply, please see the LED indicator is always on or flashing? If the LED is always on, it means that the self-diagnosis has failed and a malfunction has occurred. If the LED indicator is flashing, it means that the device works normally.

T2: What are the advantages of your video scrambler compared to other brands of scramblers?

A2: Our video scrambler provides a higher level of security and flexibility compared to many common FPV scramblers on the market. Some brands only use fixed encryption seeds, meaning users cannot customize the scrambling key. Under such conditions, even if the video is scrambled, other receivers using the same brand’s descrambler module may still access your private feed. This creates a significant security risk, especially in sensitive applications such as public safety, application de la loi, or UAV operations.

En revanche, our scrambler supports user-defined scrambling algorithms and multiple encryption seeds. This ensures that only authorized receivers with the correct key can successfully decode the video, while any mismatched receiver will only display scrambled signals. En outre, our design emphasizes stability and ultra-low latency, guaranteeing smooth, real-time image transmission without compromising security. By combining customizable encryption, robust reliability, et performances en temps réel, our scrambler offers truly secure and professional-grade protection for critical video transmission.

Simple but effective—scramble your video and prevent interception.

Defend your feed—our module ensures only authorized viewers see your video.

Quick setup, total protection—secure your video transmission in minutes.
