Abstract
In a method for protecting safety of a door. The method obtains a current image captured by an image capturing device installed in a key holder of a lock of the door, detects an object in the current image, and compares the current image with a preset key template when the object has been detected in the current image. The method further activates a safety guard unit of the door using a driving unit of the door when the current image does not match the key template, and locks a slip bolt of the safety guard unit.
