Phone security devices are similar to other counter-surveillance measures that protect your private phone conversations from being overheard, recorded, and/or monitored. We also carry phone scramblers and phone tap detectors that will notify you if an incoming call is being made from a tapped phone. Also, when used on a computer with a modem installed, this unit ensures that your data transfer from the modem is secure; when the modem is in use all extensions are temporarily cut off.

The phone line tap detectors will thwart line tapping and recording devices so that line powered transmitters, line activated tape recording controls, and all voltage activated devices will not function. Other features include LED warning lights that will indicate if someone is listening to your conversation or if a phone tap has been detected, and will then mute the audio automatically. Detect and defeat even the most sophisticated eavesdropping and recording devices so your private information is secure!

Our line of phone detection devices is easy to install and use. All units come with cords, plugs, adapters, and battery packs (when applicable).
