Tabletop Room Anti-Recorder

This table-top, medium to large room anti-recorder creates 360º of privacy protection. The NG3700 emits an ultrasonic series of intereference that distorts voice conversations beyond the ability to decode once recorded. It's unstoppable against all microphones in hidden video, surveillance cameras, pen recorders, and cell phones. With a rechargeable battery and simple on/off power switch your business meetings and negotiations can be kept private in a snap.
