Install the Telephone Tap Defeat system and use your telephone with confidence.
Protection is automatically activated.
Installation is quick and requires no technical or detailed knowledge of surveillance methods.
As it is permanently connected you can be assured of 24-hour protection against invasion of privacy.
DEFEATS AUTOMATIC TELEPHONE RECORDERS
DEFEATS TELEPHONE TRANSMITTERS
OUTSMARTS AUTOMATIC RECORDERS AND OTHER TRIGGERED DEVICES.
The equipment is designed to provide complete protection of any telephone line and be installed permanently.
Installation on any telephone line, world-wide, will take a matter of minutes
It defeats not only transmitting devices but recording equipment and other eavesdropping devices as well.
The telephone line is electronically modified and isolated so that eavesdropping equipment is rendered ineffective or paralysed altogether.
There is no necessity to be alert to warning lights or alarms.
The telephone can simply be used as normal.
Our design is based on advanced counter-measures technology.
The telephone user will be unable to detect changes in the telephone line signal but several modifications are made to the signal itself.
The signal is processed to mask frequencies of speech. High impedance eavesdropping devices (which for the most part are undetectable) cannot function.
Medium and low impedance devices are prevented from operating.
Equipment inductively coupled, another very difficult category to detect, is rendered useless.
Also effected by this processing are RF transmitters, capacitively coupled devices, transformer-coupled devices, tape recorder activators, and extension telephones and linesman?s handsets.
The second counter -measures technique to be used is the manipulation of the voltage and current characteristic of the line.
Devices utilising either voltage or current to sense the telephone is off-hook are electronically shut off and therefore no recordings or transmissions are activated.
The telephone is completely isolated from the line and eavesdropping devices such as hook-switch bypasses and infinity transmitter cannot work.
Isolation of the line prevents modification of the telephone to make it a listening device when on-hook.
