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.

Q2: 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, law enforcement, or UAV operations.

In contrast, 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. In addition, our design emphasizes stability and ultra-low latency, guaranteeing smooth, real-time image transmission without compromising security. By combining customizable encryption, robust reliability, and real-time performance, 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.

What is video scrambler module

An FPV Analog Video Scrambler and Descrambler Module is a device used in analog video systems—commonly in FPV (First-Person View) drone setups—to encrypt and decrypt video signals. Essentially, it allows you to secure the analog video transmitted over the air so that only authorized receivers can view the video feed. Here’s a detailed breakdown:

---

1. Purpose

• Prevent unauthorized viewing: In FPV drone racing, security, or military applications, you may want to prevent outsiders from intercepting your live video feed.

• Protect sensitive data: Ensures that only receivers with the correct decryption key or module can display the video.

• Maintain analog workflow: Works with standard analog CVBS (composite) or FPV video signals without needing digital conversion.

---

2. How it Works

• Scrambler (Transmitter Side):

  • Takes the analog video signal from the camera.

  • Applies a scrambling algorithm to distort the video (can be simple line inversion, signal phase shift, or more complex analog encryption techniques).

  • Outputs the scrambled video to the transmitter, which then sends it over RF (radio frequency).

• Descrambler (Receiver Side):

  • Receives the scrambled video signal.

  • Uses the matching descrambling algorithm to restore the video to its original form.

  • Outputs clean, viewable video to a monitor, goggles, or recording device.

---

3. Key Features

• Supports analog CVBS video signals (commonly used in FPV systems).

• Compact and lightweight, suitable for drones.

• Low-latency operation, crucial for real-time FPV applications.

• Some modules allow adjustable scrambling patterns or keys.

• Can be paired with multiple transmitters and receivers for secure group operations.

---

4. Typical Applications

• FPV Drone Racing: Protects live video feeds from interference or unauthorized viewers during competitive races.

• Security and Surveillance Drones: Ensures that video streams from security drones cannot be intercepted or viewed by unauthorized personnel.

• Military and Defense UAVs: Secures sensitive reconnaissance or tactical video transmissions in field operations.

• Industrial Inspection Drones: Protects video data during inspection of critical infrastructure, such as power plants, pipelines, or chemical facilities.

• Private Aerial Filming: Prevents third parties from intercepting high-value or proprietary video content during aerial filming or broadcasting.

• Government or Law Enforcement Applications: Maintains confidentiality of surveillance footage for policing or emergency response operations.

• Remote Monitoring Systems: Secures analog video signals in applications like border patrol, wildlife monitoring, or restricted areas.
