The image controller 260 may output a video input from the camera 250 to the wireless transmitter 280, or may capture a specific image and output a still image to the wireless transmitter 280. Of course, when the human body sensor 240 does not detect the human body, the image controller 260 terminates the photographing and transmission of the surveillance image of the camera 250.

The indoor terminal 300 receives the surveillance image transmitted from the wireless transmitter 280 through the wireless receiver 310, removes and amplifies the noise, and outputs the amplified signals to the terminal controller 350. The terminal controller 350 After converting the surveillance image output through the wireless receiver 310 to the appropriate data and stored in the storage unit 320 with a predetermined date and time data.

Thereafter, the user can check the surveillance image recorded in the storage unit 320 of the indoor terminal 300 through the display unit 340, and can search by date and time zone through the operation button unit 330, The microprocessor 230 retrieves the surveillance image stored in the storage 320 by date and time zone according to a command input through the operation button unit 330 and displays it on the display unit 340.

On the other hand, the indoor terminal 300 has a USB port 360 is formed so that the communication terminal 500 such as a laptop, PDA, mobile communication terminal and the like connected to each other by a USB cable storage unit through the screen of the communication terminal 500 It is also possible to check the surveillance image stored in 320.

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.

While specific embodiments of the present invention have been described and illustrated above, it will be apparent 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.
