Spies are using all kinds of eavesdropping devices to get the information they are interested in, how can we deal with it? Layers of security checks are cumbersome and inefficient, just use Speaker Shape Microphone Suppressor to prevent these devices from working.
This device looks like an ordinary speaker on the surface, with a wooden shell and 24 ultrasonic transmitters on the front panel disguised as speaker structures, which will not attract attention. It is equipped with a remote control for discreet switching.
The BU24 emits complex ultrasonic signals (inaudible to human ears) and directly applies sound pressure on the microphone diaphragm to interfere with its pickup function.
Effects include:
- Abnormal distortion of the preamplifier
- Noise and frequency drift in the radio
- The final audio file is full of distorted noise and the content cannot be recognized
Spy equipment (even if expensive and complex) will become completely useless because it cannot perform its task.
In addition to ultrasonic waves, it can also reproduce random noise similar to speech, further disrupting the pickup logic. Effectively prevent noise reduction software from restoring the recording content.
Anti-spy phone microphone jammer is applicable to, but not limited to:
- Mobile phones (including recording apps and call monitoring)
- Recorders, digital voice recorders
- Various microphone systems (wired/wireless)
- Laser pickup
- Directional microphones (parabolic, pinhole, etc.)
