Technical Surveillance Counter Measues
Contrary to what is advertised, there is no do-it-yourself magic bullet in eavesdropping detection. You can not dial a number to see if your phone is tapped. There is not any one instrument which will detect all "bugs" for you. There is no gadget, which will protect you from all wire-tappers. Technical Surveillance Counter Measures (TSCM) also known as Eavesdropping Detection or Debugging is labour and equipment and involves intensive hard work.
