TX Encryption RX Decryption FPV Video Scrambler Input Voltage 5-36V For RC FPV Drone
Key Features:
- The CVBS video stream encryption and decryption module needs to be used in pairs,one attachs to the FPV transmitter, and the other to the video receiver.
- FPGA digital encryption and decryption processing, with high-intensity 32-bit password(up to 232).
- Supports PAL and NTSC analog video stream encryption and decryption, applicable to various flight visual cameras, Thermal imaging cameras, etc.
- Through the setting of the dip switch, the same hardware module can be used for encryption and decryption operations.
- Encryption and decryption passwords can be set through serial port.
- Suitable for any FPV VTX, scrambling on the video cable square layout, suitable for assembly with VTX.
- Upgrade FPV security.
- Prevent others from viewing your private videos.

Video encryption principle
It collects CVBS video and performs analog to digital conversion, the converted digital signal is encrypted through FPGA, reprocess the video image, then output it for digital to analog conversion, finally convert it into standard CVBS format and output to the transmitter.
Video decryption principle
The CVBS video signal received by the receiver to do analog to digital conversion,decrypt the converted digital signal through FPGA, reprocess the video image, then output it for digital to analog conversion, finally convert it into standard CVBS output to the display.

FPV Video Scrambler Hardware description
The size of the module is 34.5*34.5mm, the top height is within 3mm,bottom height is within 1mm, board thickness is 1.2mm. The diameter of the fixing holes on the four corners is 2.5mm. The weight is 4.3 grams.
Dial switch
To set whether the FPV video scrambler module worked as an encryption or decryption function module. When the dip switch is turned to "on" (as shown in the above picture, turned to the left), it is used as an encryption function module. When the dip switch is turned to "I" (as shown in the above picture, turned to the right), it is used as a decryption function module.
