Abstract

The utility model relates to an intelligent night vision anti-theft alarm, which adopts human body thermoelectric infrared inducing technology. A sensor can focus the infrared ray of about 10 UM ejected by human body to an infrared inducing source through a Fresnel ray filter after being reinforced, then an electrical signal is generated, which can be taken as a probe of the human body activitiesin a certain area. The circuit adopts a light dependent resistor to control the electric potential of the base electrode of a three-electrode tube, so as to ensure that the three-electrode tube is ina cut-off state when no light is generated, and that the high potential of the base electrode is in an armed state. Upon detecting the motion of people, the heat source probe can trigger a voice and siren sound circuit immediately accompanied with a stroboscopic LED light. Once the acousto-optic circuit of the device is triggered, even if the triggering signal is interrupted, the circuit can stilllast for some time. Since the circuit can identify the light automatically, when relations go to the warning area in day or night under the condition that the light is turned on, no alarming is sentout. The device adopts double sound effects, the siren is used for warning, and the warning voice and the stroboscopic LED can act on frightening the criminals. The device is a night security guard for the sleeping porch of a building in summer.
