Consumers are turning to telephone surveillance technology to keep conversions private between them and the person on the other end of the line. If you are suspicious that someone is listening in to your calls, or that there might be a recording device hooked to your line, this inexpensive device will alert you of such attempts of eavesdropping.

Put Discrete Telephone Surveillance On All Landline Extensions

If you’ve been thinking you’re under surveillance a telephone privacy protector such as a Telephone Privacy Protector called the Tele-Data Guard (#TDG) can be used to detect possible intrusions on your private home landline. A Tele-Data Guard is a simple device that shows a light when the line voltage is unchanged, but when the light turns off it indicates you are not alone on the line. Even if you don’t suspect you’re under telephone surveillance, this gadget is great for multi-person households with a single phone line. It is especially helpful when someone else in the house has picked up an extension. Simple put one on every extension and whichever phone you pick up, it will automatically disconnect all the other extensions.
