MINI WIRE TELEPHONY BUG
This device is designed for room monitoring and transmission of informations on the sub carrier frequencies of a telephone line.
The low value of sub carrier frequency allows transmission of the intercepted informations at a distance of approximately one mile.
The information transmitter comes as an unpacked module, with external cables for microphone and telephone line connection. These kinds of transmitters, which use a fixed value of sub carrier frequency are one of the standards in the industry. The transmitter is connected in parallel to the telephone line, it can be placed in any point and with any polarity.
The receiver comes as a separate module, housed in a metallic box with leads for telephone line connection, output jacks for earphones and recorder, and an external power supply socket. The knobs for volume control and tuning, and the On/Off switch are on the front panel.
