Tapping
Interception of wired communication

This section is about receivers that are made for intercepting communication sent over wires, such as analogue telephone conversations. Such receivers are commonly known as wire tapping devices. Tapping a telephone line is not straightforward, as a device that is connected in parallel with the wiring can usually be detected quite easily. As wire tapping is also known as bugging, some of these device are also listed in our section about covert listening devices (bugs).
