Continuous digital radio support
For police forces, the digital radio era began long ago,
with the TETRA and Tetrapol procedures. So all headsets
and microphones developed by Imtradex for use by police
forces support the new digital radio standards for the
comprehensive and cross-agency voice and data communication, and ensure the security of the communications.
To ensure that no unwanted noise is generated at high
frequencies, all Imtradex systems are equipped with innovative shielding that prevents analogue radio interference.

Of course our communications accessories also support
such as communication within a defined user group.
