Block the microphones in mobile phones from recording as well as voice and video surveillance. The table-top sized anti-recorder creates an ultrasonic 360º field of interference to keep phone conversations, video meetings and in person meetings private. Ultrasonic intereference distorts voice and video transmissions so that they cannot be restored after the fact.

• Interference distance: up to 6 meters (18 feet)
• Interference angle: 360º
• Rechargeable battery: three hours of charging time
• 2-4 hours of battery life
• Silent operation: ultrasonic interference is undetectable
• Small enough to sit in a cubicle or desk
