Memory Radio Analyser Bug Detection System

MRA-3 selectively eliminates even strong local TV and radio broadcasting, or mobile and data transmitters, using a unique frequency processing combined with extra fast spectrum comparisons. Checked "bugs free" spectrum is stored in the background memory and compared with actual signals every 6 seconds. A new suspicious signal activates a 3-level alarm mechanism. The new signal is also recorded in a separate alarm memory.

In simple terms this device monitors and remembers frequencies like TV stations etc, as soon as a new RF device (possibly a bug) in detected you will be notified in just a matter of seconds.

This device is designed to stay on as a permanent protection measure.
