The Tele-Guard Telephone Security Device is effective
against most common types of phone bugs. It will
protect your telephone conversations by turning off the most
common series and parallel line tap devices such as voltage
activated tape recorders and series line transmitters
(bugs).
Green LED and audio muting
feature also instantly lets you know if anyone is listening
on another extension or even a “lineman's test set” outside
your house. Override switch lets you continue your
conversation, if desired, after you have been alerted.
Telephone line powered, never needs batteries or power
adapter.
Simple modular connection
to phone. For single line phones only. |
Was it a person in the other room accidentally picking up
the phone? Was it the phone company guy outside checking
wires? Was it a telephone recorder hidden in your
attic? Whatever it was, you will never know without a
telephone security device.
