PRIME Omnidirectional Speech Protector

Protects you from all types of eavesdropping

The efficient PRIME Omnidirectional Speech Protector is a more powerful successor to the EO-1. It ensures that your meetings remain safe and discreet. By combining ultrasonic and acoustic noise, it eliminates the risk of eavesdropping during meetings.

The omnidirectional ultrasonic noise generator blocks microphones at a range of 1-1.5 meters (3-5 ft) for modern phones and up to 3 meters (10 ft) for older models. It can even penetrate clothing and effectively cancels eavesdropping across a full 360-degree range.

With the addition of acoustic noise, you can rest assured that no one will be able to eavesdrop on you using a stethoscope or laser microphone, even from a distance of up to 30 meters (98 ft).

• Built-in and directional microphones
• Eavesdropping devices with 220 V mains supply

Ultrasonic noise

Ultrasonic noise is highly effective against eavesdropping because it can completely overwhelm microphones, degrading recordings to contain only noise. As a result, all confidential information remains safe. Additionally, ultrasound is inaudible to human hearing, so it does not disrupt the flow of the meeting.

Acoustic noise

Acoustic noise protects against eavesdropping methods that ultrasonic noise alone can not block, such as hidden microphones, stethoscopic or laser microphones. This makes it impossible to eavesdrop through walls or window panes. The device works by randomly generating words to overlay your conversation. A key advantage is that you can record your own voice. That requires a quiet environment and maintaining a distance of 10-20 cm from the device.

Easy to install

The omnidirectional speech protector is easy to set up with no need for complex configurations. Everything is conveniently controlled via the remote control or with a single button on the device.
