Abstract

Abstract A personal surveillance system having a video camera and an audio microphone in a single package sufficiently small to be worn as a badge, lapel pin, or similarly small accessory. The audio/video package is coupled to a transmitter for transmitting an audio and video signal to a remote station. The remote station comprises a video cassette recorder responsive to a signal for recording that is generated on a continuous basis by the audio/video package in a signal band that is filtered before recording.
