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.
