Security system

Abstract

A new security system for monitoring and recording activity within the range of a proximity detector is disclosed. The security system also enables an occupant of a house, building or other structure to communicate orally with a person who approaches a door or other threshold either through means disposed at the door or other threshold or remotely. A remote unit allows a person to monitor the activity at the door or other threshold remotely as well as to play back recorded activity. The inventive device includes a video camera for generating a video signal, a video monitor operably coupled to the video camera, a proximity detector for generating a first signal representative of motion proximate the video camera, a microcontroller operably coupled to the proximity detector wherein the microcontroller is further operably coupled to the video camera and to the video monitor through a video recording and playback device and wherein the microcontroller further includes firmware for activating the video camera and the video recording and playback device in response to the first signal.
