Audio transmitter bug for room monitoring and landline phone tapping. With encrypted radio channel and remote control!

This bug transmitter can be used both for land line call listening and room monitoring, using a crystal controlled radio channel. All the features can be defined by the user and can be also set by a remote radio controller.

The ENRMTK 100 is available both in standard and light versions. Light version does not include a RC unit and does not offer the digital encryption option. The digital "Delta Modulation" encryption method keeps data safe from any possible interception, since the signal has no voice attributes. Coming with two output power modes: one at 30 mW, suitable for long time work, and one at 100mW which widens the operational range.

Especially important is Voice Activation function able to activate the transmitter only when this latter detects a signal from landine or microphone, stopping any transmission within a certain period of time if no more signals are detected. The voice activation system ensures a longer operating time.

The transmission unit is equipped with external microphone, charge plug, SMA plug for external antenna, rechargeable battery, ON/OFF switvh as well as power state indicator.

For land line phone tapping, the module connects in parallel directly on the wires of the line to be monitored.

Customizable basic functions defined by user:

Clear or encrypted radio channel (Delta Modulation encoding).

Output power adjustment (30 mW / 100 MW).

VOX ON/OFF function.

Radio remote control ON/OFF.

The transmitter can be turned ON/OFF via RC.
