Description
This is the book that security professionals, security system installers and hobbyists have been waiting for. Paul Brookes launches straight into the practicalities of electronic surveillance with plenty of clear, detailed information on building the devices that are at the heart of surveillance and counter-surveillance. Self-build electronics projects are supported by principles and a brief survey of each type of device. The second edition of this popular handbook has been extended with new material on microphones, amplifiers and transmitters.
