Telephone Extension Monitor

[EXTMON]

Availability: In stock

This simple to use phone-monitoring device is compatible with any regular telephone jack on a single line system.

By inserting the phone-monitoring unit into any jack on the system the user can covertly monitor telephone conversations without any tell-tale clicks, noises, voltage drops or volume decreases that would regularly signify interference.

The listening device can either be used in tandem with the caller with the aid of a line splitter (not supplied) or covertly from another room in the building to secretly monitor suspect conversations.

The phone monitoring unit is powered by the line and is supplied with a discrete earpiece.
