Abstract
A system for observing and recording the activity between a practitioner such as a psychiatrist or doctor and a patient includes zoom lens video camera and a microphone having output signals mixed and fed through a delay network to a high capacity tape recorder together with a date/time signal and a remote control for adjusting the recorder speed between a normal recording speed and a dormant slow frame time lapse speed. A monitor is coupled to the mixed signals and the field and orientation of the camera is remotely controlled by the practitioner. A sound or motion sensor may switch the recorder from slow speed to normal recording speed; or in other situations which so dictate, it may initiate the dormant slow frame time lapse speed--regular or random--and so remain.
