Digital Encryption modules for Tait radios

Wire-in Encryption modules
Our easy-to-fit 256-bit AES Digital Encryption plug-in modules easily convert Tait analogue radios into secure digital radios and therefore:

  • Works seamlessly.

  • Guards against eavesdropping or unauthorised listening.

  • the host radio's audio is dramatically enhanced and becomes  much clearer due to the digitising process.

  • There is a dramatic reduction of interference from other radio traffic as during the digitising process interference is almost totally eliminated.

 

Our Digital Encryption modules easily convert your Tait analogue (analog) radios into digital radios with secure 256-bit AES Digital Encryption for highly secure Encryption and protect your calls from eavesdropping or unauthorised listeners!

The NDB-750t is digital encryption plug-In module designed to plug into Tait radios and work seamlessly through radio repeaters.

The modules are also available with an optional OTAR Management System for:

  • Over-the-air monitoring of calls
  • Call logging
  • Interception or locating of stolen or missing radios
  • Over-the-air programming of encryption keys

These are just some of the Tait radios which can install our plug-in modules:
- Orca 5000 Series Portables,T2000 and T8000 Mobiles radios, equipped with special flex (supplied by Tait).
