Miniature 100mW Digital Wireless Encrypted Transmitter



The E-SOL4-BODYWIRE is an advanced COFDM digital video transmitter for covert or body-worn applications. Extremely small in size, the unit has been designed to allow reliable video transmission in non-line-of-site, mobile or battery powered applications. These applications include wearable camera systems, UAVs or covert video hides. The unit has a single analog video input and stereo audio inputs.

Unlike analog video transmission systems, COFDM systems utilise digital video compression and multiple carriers to achieve superior performance.


  • 1 Video Input
  • Stereo Audio Inputs
  • 750mA 12VDC Operation
  • Encrypted Signal
  • Programming via RS232
  • Non-Line-Of Site Operation 


Any standard analog composite video and/or audio signal can be connected to the unit. This signal is encoded into a digital stream, encrypted, then transmitted wirelessly to a compatible receiver. The receiver unit decodes and decrypts the video and outputs the signal as an analog video signal. It is the first transmitter of it's kind to offer user selectable MPEG2 or MPEG4 image compression (MPEG-4 is optional). The standard 32-bit encryption can also be upgraded to AES128/256 bit encryption if required.
