The AJ34 White Noise Generator is a fully portable and easy to use counter surveillance tool.
The AJ34 is effective against all types of microphone based listening devices. Simply switch the device on and select the appropriate volume to generate an unfilterable sound that will mask any conversation held at a lower decibel level.
The sound generated varies in frequency and amplitude making it impossible to isolate even with professional audio software. The AJ34 White Noise Generator is effective against all RF transmitters, hard-wired microphones and tape recorders, and will protect a room of up to 150 sq. ft.
The white noise generator is powered by 1 x 9v PP3 battery (supplied) which will give several hours of use.
