Bluetooth Secure Listening Device
Discretion and Security
This "store and forward" system is based on "relay-microphones" modules and an Android base for configuring, listening in real time and downloading audio recordings. Each relay-microphone module is equipped with a 120 GB memory, allowing to record more than a year of audio signals. Thanks to their compact size (44x41x13 mm) and low consumption level these modules can be easily concealed. There are also IP relay modules. Each module can have Mic Rel a range up to 1km Mic Rel (LOS). Communication and data transmission are carried out on frequency jumps and spectrum spread, making it almost impossible to detect these units. The configuration of the network is done on the touch screen of the Android base simply by moving the icons.
