FPV视频加扰器 发送端TX加扰加密模块 接收端RX解扰解密模块
Please don’t share FPV videos with strangers, it’s time to encrypt video! You might also consider a COFDM digital video transmitter and receiver with AES128 video encryption. FPV1887
目录
特征
- Lightweight design
- Pair use (one add at the FPV transmitter, another add at the video receiver)
- Scrambling and descrambling modules are the same. Users can define the scrambling or descrambling function in the software.
- Some buyers need 10 scrambling modules but only one descrambling module on the ground.
Video Encryption Principle
We collect CVBS video and perform AD (analog-to-digital) conversion, encrypt the converted digital signal through FPGA, reprocess the video image, and then output it for DA (digital-to-analog) conversion, and convert it into a standard CVBS output to the transmitter.
Video Decryption Principle
We convert the CVBS video signal received by the receiver into AD (analog-to-digital), decrypt the converted digital signal through FPGA, reprocess the video image, and then output it for DA (digital-to-analog) conversion, and convert it into a standard CVBS output to the display.

故障排除
特殊情况说明: 由于摄像机视频幅度的差异, 视频发射器, 以及不同厂家生产的视频接收器, 使用过程中视频亮度可能不够. 如果发生这种情况, 请按照以下步骤修改模块.
1. 首先拆掉上面的电阻 “1” 位置.
2.如果视频幅度仍然不够, 去掉电阻上 “2” 头寸并做空.

How to test the FPV Video Scrambler and Descrambler Module?
常问问题
Q1: What is the added latency of these FPV Video Scrambler and Descrambler modules?
一个: After adding our scrambler and descrambler modules, the delay may increase by 0.1 至 1 毫秒.
Our AHD / CVBS camera latency:
Q2: What is MOQ for OEM for FPV Video Scrambler?
一个:
- For orders of more than 500 件, the PCB color and post-welding can be changed.
- For orders of more than 5,000 件, the PCBA structure can be changed.
- For orders of more than 15,000 件, the encryption Algorithm can be changed. It is a completely customized production and cannot be descrambled by others.
Q3: What are the dimensions and weight of a package of 500 件?
A3: One carton, carton size 39x31x23cm and 4.5kgs.
第四季度: Can it be programmed? Or is it pre-set to 10 scramblers + 1 descrambler?
A4: 是, it is programmed. The scrambler and descrambler hardware are the same. You can define the functions or usage roles of the modules on your computer through the software we provide (CVBS加扰助手).
Q5: May we use your video scrambler with other analog video transmitters and receivers that we may buy on aliexpress?
A5: 当然, it is no problem to use our FPV scrambler on other brands’ analog video transmitters and receivers. We only added a scrambling algorithm to the video, which makes it impossible for the video to be displayed normally on the monitor. It has nothing to do with the frequency and model of FPV VTX VRX.
Q6: What encryption and decryption algorithm does your video scrambler use? Is it AES128?
A6: It is not encryption or decryption. It is video scrambling. Simply put, it completely scrambles the video’s queues through an algorithm.
In our test video on YouTube, you can see that if we input the same encryption algorithm serial number, we can see the video. If we input a different encryption algorithm or do not use a descrambler, the video content is abnormal.
Q7: How to quickly test your FPV video scrambler and descrambler without an FPV VTX VRX?
A7: 请检查下面两张图片. 我们刚刚连接了一台 CVBS 模拟摄像机, 1个扰码器模块, 1个解扰器模块, 和一台显示器来验证功能.
Q8:Do you have any new designs or features of your FPV Analog Video encryptor decryptor module?
A8: 我们将根据客户在FPV中遇到的问题和反馈以及实际使用场景不断完善我们的产品. 下图是我们10月最新版本 2024. https://ivcan.com/p/fpv-analog-video-scrambler-and-descrambler-module/
此外, 如果您有任何希望或建议, 请告诉我们, 我们的工程师会仔细评估并不断优化.
Q9: Does this module work on 1.2-1.3ghz Analog frequency?
Q10: Can you tell me the minimum and maximum voltage supply need?
A10: 5-12V. 所需的最小电压为5V.
最好使用12V, 因为用较低的 5V 供电有问题.

Rest assured that the military-grade security systems will provide us with the peace of mind we deserve, safeguarding our valuable assets and ensuring our safety. During urban drone surveillance testing, an encryption algorithm seed exceeding 100,000 ensured that our feeds remained completely private and secure from any unauthorized access or interception. We no longer need to worry about the risk of hackers intercepting and potentially misusing our sensitive footage.
