[0015] Beneficial effects

[0016] This utility model provides a concealed, inward-opening security door with a flat outer surface, which has at least the following advantages compared with the prior art:

[0017] The system uses a camera or fingerprint scanner to recognize a person's face or fingerprint. Once a match is successful, the automatic lock inside the door opens. At this point, the electric push rod retracts, moving the connecting frame and connecting strip. This causes the upper slider to move down and the lower slider to move up, moving the sliding block and positioning block along the groove. The positioning block then moves out of the limiting groove in the door frame, disengaging the door from the frame. Pushing the door inwards opens it. This anti-theft mechanism enhances the structural strength of the connection between the door frame and the door, improving security. The outer side of the door is flush with the outer side of the door frame, improving aesthetics and concealment, indirectly enhancing security. Attached Figure Description
