Product details
Full description
Help Keep Conversations Private
The AJ-100 generates audible random white noise to help mask speech from nearby microphones, including those in hidden listening devices, voice recorders, transceivers, and cell phones.
The sound changes in frequency and amplitude to make filtering more difficult. Effectiveness varies with the microphone, recording technology, noise level, and room conditions; complete suppression of every recording is not guaranteed.
Simple Controls. Portable Design.
The pocket-size unit is ready to use once batteries are installed. Adjust the noise level to suit the room and your conversation. Its four batteries are replaceable and are not included.
Battery life is rated at up to several days under ideal conditions. Actual runtime varies with use and the batteries installed.
