Abstract
An infrared detector includes a light emitter and a light receiver. The light emitter has plural light emitting units. A circuit connects the light emitter with a CPU programmed decoder and a power amplifying controller. A special coded signal is amplified and emitted out with an infrared light beam by the light emitting units to a light receiver. The light receiver has plural infrared light receiving units. A circuit connects the receiving units with a signal amplifier, a CPU programmed calculating and comparing decoder, and an output controller. The special coded signal with the infrared light beam received by each separate infrared light receiving unit is simultaneously sent to the signal amplifier for amplifying and to the CPU programmed calculating and comparing decoder for processing and controlled by the output controller. Thus, the infrared detector is prevented from being disabled by an unauthorized code or a different code by an unauthorized person.
