Abstract: A detection warning system for caregivers in a home alerting a caregiver when a child, elderly or physically challenged person tries to exit a bed, room or walk through a doorway without the aid of a caregiver. This detection warning system comprises of two small fire retardant enclosures and an external reflector. A portable infrared emitter detector base unit enclosure placed parallel to a bed, across a room or doorway, houses an emitter and detector in an emitter detector module with a narrow, infrared beam and a transmitter in a transmitter module. A portable receiving unit enclosure placed anywhere in a home contains a receiver module and an adjustable audio alarm. An emitter in the emitter detector module in the portable infrared emitter detector base unit emits a narrow, infrared beam to the external reflector located at a predetermined distance in alignment with the narrow, infrared beam which reflects back to a detector.
