Telephone systems are becoming increasingly more complex, with many companies having their own internal electronic exchange. In some ways, this makes the eavesdropper’s job more difficult, as it does the job of Detection. However, as telephone bugs are likely to use the telephone line to supply the necessary power, it is possible to detect them by measuring telephone line parameters. This checks the line from the telephone itself back to the Main Distribution Frame (MDF) where the telephone cables come in from the street.
We at Listening-device-detection-services have invested in the most up to date equipment. Telephone tapping is on the increase, one of the main reasons is the availability of cheap imported listening devices/bugs.
Since telephones are designed to transfer information from one place to another, they obviously require special consideration in counter surveillance work.
Considerable time and experience is needed to carry out a comprehensive examination of telephone systems, since there are so many variations, and information on a particular installation encountered is ofter meagre.
Telephone taps transmit voice information down the existing line, either to an eavesdropper somewhere along the line from the telephone to the MDF – or even to the exchange, or to a distant location via the telephone system as a whole. Telephone bugs transmit radio information to a nearby location (such as a car parked outside), and may operate only on telephone conversations, or additionally also on room conversations, Thus, Listening-device-detection-services carries out all radio sweeps with telephones operated off-hook. These listening devices/bugs may be cheap imports, however, they can still ruin your businees. so Detection of the Device is essential.
