The F-10 ultrasonic acoustic sound wave generator anti-recording guard emits ultrasound waves to interfere with microphones. This includes smartphone, tablet, digital recorder, hardwired and wireless listening device and microphone on cameras. It overrides / interferes with microphones used to monitor, record, listen to frequency covered in speech / voice.
F-10 is a 5v/4000mA portable design to place on table / desk near recorder / listening device / camera. It has 1.5-3 square metre range with 300º coverage ideal for placing next to microphone. This completely overrides microphone to only hear ultrasonic noise. It also has wireless remote control to discreetly and conveniently turn on/off. USB powered connected to standard phone charger or battery power work time 60-120 minutes.
Simply place close microphone or between you and suspected area and switch on to emit acoustic sound wave to override microphone.
The effective distance to completely override microphone is within 1.5 square metres over 90º-300º coverage. No voice/conversation or sound can be heard when placed close to microphone. When used you can hear a mild hum if pointed or placed near your ears. It is not recommended to use close to pets / animals as they can hear ultrasonic frequency more clearly than humans.
The principle of the anti recording guard is to emit ultrasound acoustic waves that interfere / override normal function of microphones. Its core technology is an advanced algorithm and chip which generate ultrasonic sound waves targeting microphone frequency.
