Although the moving picture or the still image can be stored in the storage 320 of the indoor terminal 300, it is preferable to store the still image captured by the image controller 260 on the memory capacity of the storage 320.

When capturing the video, the image controller 260 compares the initial screen, which is not detected by the human body, stored in the initial screen memory 270 with the surveillance image input from the camera 250, and selects an image representing the largest image change. Capturing by time is best because it captures the human body best.

In addition, the initial screen stored in the initial screen memory 270 may set and change the initial screen input from the camera 250 through the mode setting of the key input unit 210.

Although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be embodied in various modifications by those skilled in the art. Such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, but should fall within the claims appended to the present invention.

Therefore, in the present invention, by adding the function of collecting and storing the image of the outside of the door to the electronic door lock can enhance the convenience and security functions at a simple and low cost, and also separates the door lock device and the storage device of the indoor terminal from the intruder There is an advantage that can protect the image data.

In addition, by installing the human body sensor in the door lock, only when there is a person close to the door can be taken to reduce the capacity of the memory, and if necessary, it is possible to save the still image to search by date and time zone for convenience There is an advantage to improve.
