INDUCTION TELEPHONE BUG
This device is suitable for telephone line monitoring with no direct contact, and transmission of the relevant informations.
The transmitter is placed in a metal case with built-in compartment for 2 AA batteries, external inductive sensor, power switch and flexible external antenna.
The sensor and transmitter can be placed in any point of the phone line. The inductive sensor is connected on one of the two line cables. Its removable cover makes it easy to install, on any type of telephone wires.
In order to save power and maximize the operating time, the transmitter features an automatic activation circuit which turns the transmitter ON when an audio signal runs along the telephone line, and goes OFF within a certain period of time after the signal stops.
Its automatic activation algorithm considerably reduces false alerts created by noises running over the telephone line.
