TSCM History - An ad for electronic surveillance bugging device, as reported in 1960.



      “A new departure in civil and criminal detection methods, which is being used successfully by New York City police detectives.”


      This complete unit can be easily concealed on the body and can be used instantly and unobtrusively in all circumstances. Its performance is superior to that obtained by using large, cumbersome devices.


      The device is furnished complete in carrying case and consists of a midget high power amplifier with small pocket size batteries, two tiny receivers which fit in the ear and can be used either dual or individually, together with the followings attachments:


1. An induction coil for picking up both ends of telephone conversations without any physical connection to the instrument or wires. Both ends of a telephone conversation can be picked up through a solid wall and listened to in an adjacent room. Both ends of a telephone conversation taking place in a telephone booth can be picked up by standing outside of the booth or occupying the adjacent booth. Both ends of the telephone conversations can be picked up anywhere along a telephone wire or at a telephone terminal box without any connection to the wire.


2. A contact microphone is included for listening to room conversations through solid walls and doors.


3. A standard small acoustical microphone is included for concealed microphone work or for listening through key holes or at door jambs.
