Secure Tourguide Systems

From courtrooms replaying audio evidence to industrial training for commercially-sensitive projects, we have tour guide products to keep your tour talk confidential.


Digital encryption

Digital encryption is available on several radio tour guide systems, adding a layer of security to your wireless audio headsets. Meetings in business, public sector, legal services, court rooms and law enforcement may request secure transmission systems to protect confidential discussions and that of the interpreter at multi-language events. Here at Apple Sound Ltd we have portable, tourguide systems that provide a high degree of privacy. 

Tour Guide Systems with Secure Encryption

ListenTALK from Listen Technologies

Conversations within a ListenTALK Group are encrypted by a unique Pair Key which separates Groups from one another and ensures secure conversations within each Group. The Pair Key is generated by the Group’s Leader and shared with each Sub-Leader and Participant. When Sub-Leaders add new Transceivers to a Group, they pass the Leader’s Pair key to these new group members. ListenTALK can be set to generate its random key-code each time it is activated, so the encryption key between devices is always different. Read more...

Digi-wave from Williams AV

The Digi-wave 300 series radio tourguide system utilises digital encryption with 1024 possible group codes and 10,000 possible Key Code combinations - available to hire.

The latest Digi-wave 400 series allows an Advanced Encryption Standard (AES) 128-bit encryption to be added, on top of the 87-bit encryption, plus a 4-digit PIN code. It is likely that a communication would be finished long before a 'brute-force' trial-and-error cracking attempt would succeed.
