This book presents theoretical principles of electronic surveillance devices and practical instruction for their use.
Abstract
The book contains discussion of why various types of equipment are used (for security reasons such as monitoring peripheral areas of property; in pursuit of hobbies; to check on spouse loyalty, the misuse of telephones, etc.), illustrated with two case histories. It also describes types of devices (including room and telephone transmitters, switching devices, and video devices), their performance and potential uses. Circuit diagrams are included for electronics engineers involved in developing security devices, and to show security personnel available devices and how they function. There is a separate chapter on receiving equipment that can be used for electronic surveillance countermeasures and techniques for their use. Finally, the book examines how private citizens may be targets of eavesdropping, without any special equipment, and may be inadvertently disclosing details of their business and private lives when they use cellular telephones, cordless telephones, wireless intercoms, and citizens band and amateur radios.
