Guard A1 – Anti-Recording Jammer

Description

Guard A1 – 360°Anti-recording jammer for mobile phones

Our 360° anti-recording jammer, with ultrasonic low-frequency interception, offers protection up to 8 meters. With this technology, the ultrasonic voice recorder blocker prevents audio recordings, video recordings, as well as cell phone recordings, thereby ensuring confidentiality in phone conversations, video meetings, and face-to-face discussions. Moreover, it securely processes voice information, so that any intercepted data cannot be recovered. Also, because the audio jammer is equipped with a rechargeable 8000mAh high-capacity battery, Guard A1 provides 2 to 4 hours of continuous operation, making it ideal for maintaining privacy in various settings.

Place the jammer on your desktop or install it under the desktop.

How It Works
The Guard A1 uses ultrasonic low-frequency sound waves that are inaudible to the human ear, yet powerful enough to interfere with the microphones in mobile phones, voice recorders, cameras, and other recording devices. As a result, these sound waves distort and mask the captured audio, ultimately making the recordings unintelligible. In contrast to RF jammers, which block wireless signals, ultrasonic audio jammers operate at the acoustic level, therefore focusing solely on preventing sound capture rather than cutting off communication.

Audio Jammers vs. Signal Jammers

• Audio Jammers: Disrupt microphones using ultrasonic sound waves, protecting against unauthorized audio and video recordings without affecting phone calls, WiFi, or GPS signals.

• Signal Jammers: Block wireless communication signals (cellular, WiFi, GPS, Bluetooth), preventing devices from connecting or transmitting data.

Legal Considerations
The legality of using ultrasonic anti-recording devices varies by country. For instance, in some regions, they are permitted for personal privacy protection in offices, homes, or vehicles. However, in others, restrictions may apply, particularly in public spaces or government facilities. Therefore, always check your local laws before using such devices.
