Noiseless Audio Recorder Suppressor

code: B31 - Professional Jammers

Advanced technology. No noise at all. Blocks 85% analog recorders. Working frequency 100~20000Hz. Makes recorder only take BUZZ noises. Remote control turns on/off. 1-year warranty.


Nowadays, there are so many digital recorders abused and infringed, from personal secrets, business information and personal privacy.

In order to protect conversations from being recorded by unauthorized recorders, the Noise Audio Recorder Suppressor can effectively block the digital or tape recorders. It works between 100Hz and 20000Hz and makes spy audio recorders take records of "BUZZ" noise but they can not record any normal conversation contents.

Unlike the white noise generator, the noiseless audio suppressor makes no noise at all. The mass codes have been compressed and transmit to the outside via ultra high-gain antenna which is built in the case.

It can block 85% of the analog recorder equipped with wire or no wire microphone. It can not block recorders built-in mobile phones according to real tests.

The outstanding strong output power ensures that the conversation cannot be recorded. If used in big conference rooms, you need to use 2~3 units together. They will not interfere with each other.
