Ultrasound Microphone Jammer Stop Bugs / Voice Recorder / Hidden Camera from Working
The first ultrasonic acoustic wave anti-recording guard that emits low frequency ultrasound wave that interferes with all microphone on media devices. This includes smartphone, tablet, digital recorder, bugging device, phone bug, wireless listening device, hidden camera. In fact it eliminates anything with a microphone that monitors, records or transmits sound.
Simply place where sensitive or private conversation is to take place and switch on anti-recording guard. It emits acoustic wave that overrides any microphones nearby.
The distance covered is 1.5-3 square metres over 90º-360º coverage. No voice/conversation or sound can be heard on any microphones when in use and human ear only hears a mild hum when pointed directly at you within 30cm.
The principle of the anti recording guard is to emit ultrasound acoustic waves that interfere's with the normal function of microphones. Its core technology is an advanced algorithm and chip which generate and run ultrasonic sound waves targeting the transmission frequency of sound media. Resulting in 4 models of military grade ultrasonic generator anti-recording shield.
