INTRUSION WARNING AND AUTOMATIC HOUSE LIGHTING SYSTEM

摘要

An intrusion warning and automatic house lighting system is characterized by automatic switching on at night at least one night or decorative light through actuation by a photocell, by switching on exterior spotlights for a time interval in response to illumination of the photocell by the headlamps of a coming automobile, by switching on and off at least one convention house wiring light with such spotlight or independently of it, and to sound an alarm upon intrusion, and by a selector switch to selectively disconnect such conventional house wiring light from automatic operation with such spotlight.
