Authenticated Remote Monitor

Authenticated Remote Monitor is a standard feature in certain MOTOTRBO radios. This feature prevents a radio from being remotely monitored by a Bad Actor.

Remote Monitor is one of many features supported by the majority of MOTOTRBO radios. This feature is useful in emergency situations where the operator or supervisor can make a target radio automatically PTT (without the users knowledge) allowing them to hear what's going on. Someone with ill-intentions could misuse this feature to spy on the user or to find their location using RDF techniques.

Authenticated Remote Monitor prevents the above by introducing a challenge-response mechanism. This means that in order to remotely monitor a target radio, the source radio user needs to enter a passkey. If the passkey matches that which is provisioned into the destination radio, it will PTT. If the passkey is no match, the radio ignores the received remote monitor request.

Models Supported

Authenticated Remote Monitor is standard in all ION; SL4010e; DP3xx1e; DP4000e and DM4000e series models shipped in EMEA after November 2019. Prior to this date, a SL4010e; DP3xx1e; DP4000e or DM4000e will need a CfS License. The same is true for the non-e SL4000; DP3xx1; DP4000 and DM4000 series. Authenticated Radio Disable is not available on lower tiered models (e.g. DP2400) or the first generation.

Configuration

Authenticated Remote Monitor is mutually exclusive with (regular) non-Emergency Remote Monitor in that only one can be enabled and used.

There are two options for the mode:

• User Authentication. The source radio user must enter the passkey.
• Device Authentication. The destination radio will be disabled if the passkey matches without the source radio user needing to enter the passkey.
