Starting with a lively history of spies and spying from the earliest times, this book reviews all aspects of audio surveillance. It describes how to monitor everything said in a room or over telephone/fax/cellular communication systems. It tells how to achieve surveillance without having to physically access the premises; how to eavesdrop from the other side of the world; how to monitor for indefinite periods of time; and how to come up with evidence strong enough to stand up in court. These are the secrets and solutions used by the world's leading spy organizations, law enforcement agencies and industrial espionage experts.
Surreptitious eavesdropping devices, miniature microphones, transmitters (bugs) telephone wiretaps, body wires and directional microphones are just of the few products and applications covered in what is considered to be the most comprehensive reference and research guide available today on the subject. Written in layman's terms, the book explains in detail just how and why devices work, allowing the user or technician to make intelligent decisions in terms of what to use or look out for, and how to design, customize or upgrade existing equipment.
