Active infrared anti-theft alarm



The invention relates to an infrared anti-theft alarm, and discloses an active infrared anti-theft alarm. The active infrared anti-theft alarm comprises an infrared emission module, an infrared receiving module and a master control module, wherein both the infrared emission module and the infrared receiving module are electrically connected with the master control module; the infrared emission module can provide three levels of infrared pulse strength; the master control module is used for control according to the infrared pulse strength received by the infrared receiving module; the infrared emission module generally works at low-level strength; thus, the reliability of an infrared light emitting diode can be improved, and the service life of the infrared light emitting diode can be prolonged.
