A remote-controlled audio-visual alarm system for normally invisibly mounting in corner soffits of a house and being in the corner soffits of the house so as to be highly visible and not obstructed when activated. The system includes at least one transmitter, at least one receiver, and at least one alarm. The alarm includes a stationary portion for invisibly mounting in any corner soffit of the house, and a movable portion that is movably mounted in the stationary portion thereof. The stationary portion includes a housing sleeve for invisibly mounting in the corner soffit of the house. The movable portion includes a neck sleeve that is movably mounted in the housing sleeve and retracts and extends therefrom, and is completely hidden therein when fully retracted so as to be normally invisible, but when any transmitter is activated, automatically extends out of the housing sleeve, and a head that is movably mounted to the neck sleeve, by a ball and socket, so as to allow the head to swivel into any preset position and face a desired direction depending upon which corner soffit of the house the alarm is mounted in when the neck sleeve is extended. The head contains visual and audible devices which are automatically activated when the movable portion is extended out of the stationary portion, which occurs automatically when any transmitter is activated.
