Intelligent electronic door viewer
The invention relates to the technical field of door viewers, and specifically relates to an intelligent electronic door viewer. The intelligent electronic door viewer comprises an infrared illuminating lamp, an optical structure, a camera, a door-outside loudspeaker, a door-outside microphone, a far-infrared probe, a door-outside photoresistor, a lock-inside photoresistor, a handle contact, a lock tongue contact, a doorbell button, a 6 V direct current power supply, a 3.3 V voltage-stabilizing circuit, a master control chip, a clock circuit, a crystal-oscillation circuit, a reset circuit, an SD card storage circuit, a touch control liquid crystal display screen, a door-inside microphone, a door-inside loudspeaker, a Wi-Fi transmission module, and a power indicating lamp. The far-infrared probe can determine whether there is someone approaches the door, the handle contact is matched with the lock tongue contact so that whether there is someone trying to unlock the door without keys can be determined, and the lock-inside photoresistor is positioned at the inner part of a lock so that whether the lock is destroyed by violence can be determined. Compared with the prior art, a sensor employed by the intelligent electronic door viewer is simple and effective, mode determination is intelligent and various, and the security of access control can be effectively improved.
