What is AES Encryption?
AES  (Advanced Encryption Standard) is the latest high-level encryption with 256 bit algorithm used in all our products to ensure the maximum speech security possible

Are calls on my mobile phone secure?
NO! without encryption they are not and almost anyone can buy a listening or monitoring device to intercept your calls.



Digital Encryption modules for wire-in into other radios

The Nabishi NDB-750w Modules are designed for wire-in installation into those radios which do not have a facility socket and so therefore the modules must be wired in. The modules will fit most professional two-way radios including Kenwood and many others.

What does it sound like?
Eaves-droppers will only hear "white noise" if they listen to a digital encryption transmission. When listening to analogue encryption they will hear scrambled speech.
