How It Works
The Guard A1 uses special ultrasonic sound waves with a very low frequency. These sounds cannot be heard by people, but they are strong enough to disturb the microphones in phones, recorders, cameras, and other devices. Because of this, the recorded sound becomes distorted and impossible to understand. Unlike RF jammers, which block wireless signals, ultrasonic audio jammers work only with sound, stopping the recording process without interrupting communication.

Audio Jammers vs. Signal Jammers

• Audio Jammers: Use ultrasonic sound to block microphones. They protect against unwanted audio or video recording without affecting phone calls, WiFi, or GPS.

• Signal Jammers: Block wireless connections like mobile networks, WiFi, GPS, and Bluetooth, stopping devices from sending or receiving data.

Legal Considerations
The rules for using ultrasonic anti-recording devices are different in each country. In some places, they can be used at home, in the office, or in your car for privacy. In other places, there are limits, especially in public areas or government buildings. Always check the laws in your area before using these devices.
