Telephone Tap Detector

This advance detector offers several levels of protection against eavesdropping attempts, more than any other device of its kind.

Whether you are on or off the phone, line voltages are constantly monitored and displayed, alerting you to almost any type of bugging device on your line. In addition, taps are neutralized or deactivated for the highest level of privacy protection. Even voice activated systems are rendered useless with the built inn Anti-VOX system.
