4 is a flowchart of a control method of a door camera system having a visitor recording function according to a second embodiment of the present invention.

As shown in FIG. 4, the control method of the door camera system having the visitor recording function according to the second embodiment of the present invention includes determining whether a visitor detection signal is present from the doorbell 220 or the human infrared sensor 230 (S11). )Wow; Photographing an image around the visitor (S12) when the visitor is detected in the step (S11); Storing data on the image photographed in the step S12 in a memory 270 (S13); Outputting the image data stored in the step S13 and storing the image data in the computer 25; In operation S13, the method may include erasing image data stored in the memory 270 (S15).

The operation of the door camera system having the visitor recording function according to the embodiment of the present invention by the above configuration is as follows.

First, the first embodiment will be described.

When the homeowner is absent, when the visitor 1 comes to the doorbell and presses the doorbell 20 installed on the door 10 (S1), the door camera 3 is operated.

If the visitor 1 is in front of the door 10 for a predetermined time without pressing the doorbell 20, the human body infrared sensor 30 detects the visitor 1 (S1) and the door camera 3 is operated. .

The controller 90 of the door camera 3 controls the operation of the door camera 3 when the visitor 1 is detected by the doorbell 20 or the human body infrared sensor 30, and at this time, the CD camera 40 Captures an image of the vicinity of the visitor 1 and outputs image data (S2).

The CD camera controller 50 controls the photographing operation of the CD camera 40, receives the image data output from the CD camera 40, transfers the image data to the analog / digital converter 60, and provides an analog / digital camera. The conversion unit 60 converts the image data output through the CD camera control unit 50 into digital image data and outputs the digital image data.

The compression / recovery unit 80 compresses the digital image data output from the analog / digital converter 80 under the control of the controller 90 and stores the digital image data in the memory 70 (S3).

As such, when there is a visitor 1 in the absence, the door camera 3 captures an image of the visitor 1 and stores it in the memory 70.

On the other hand, when the homeowner returns home and operates the play button 100 of the screen display unit 5 to check whether the visitor 1 is present (S4), the compression / restore unit 80 of the door camera 3 controls the control unit. Under the control of 90, the image data stored in the memory 70 is restored and output to the screen display section 5 (S5).

Then, the digital / analog converter 110 of the screen display unit 5 receives the digital image data output from the door camera 3 and converts the image data into analog image data. The converted image data is converted into the cathode ray tube 120. By the corresponding screen (S5).

In this way, the screen displayed on the cathode ray tube 120 shows that the visitor 1 has been absent and can also confirm who it is.

Of course, even the visitor 1 who came for theft or another purpose other than the normal visitor 1 can be confirmed.

In addition, the door camera 3 further includes a clock and stores the visit time information in the memory 70 when the image of the visitor 1 is photographed and stored, and is reproduced together when played by the user. Make sure you know the time you came.

Next, a second embodiment will be described.

When the homeowner is absent, the visitor 1 comes to press the doorbell 220 installed in the door 210 (S11) and the door camera 23 is operated.

If the visitor 1 is in front of the door 210 for a predetermined time without pressing the doorbell 220, the human infrared sensor 230 detects the visitor 1 (S11) and the door camera 23 is operated. .

The control unit 280 of the door camera 23 controls the operation of the door camera 23 when the visitor 1 is detected by the doorbell 220 or the human infrared sensor 230, and at this time, the CD camera 240 Captures an image of the vicinity of the visitor 1 and outputs image data (S12).

The CD camera controller 250 controls the photographing operation of the CD camera 240, receives image data output from the CD camera 240, and transfers the image data to the analog / digital converter 260.

Next, the analog / digital conversion unit 260 converts the image data output through the CD camera control unit 250 into digital image data, and stores the image data in the memory 270 under the control of the control unit 280 (S13). ).

As such, when the image data is stored in the memory 270, the controller 280 transmits a message to the computer 25 to receive the image data, and controls the memory 270 to transfer the stored image data to the computer 25. To output (S14).

Meanwhile, the computer 25 receives a message for receiving image data from the control unit 280 of the door camera 23, and then receives the image data output from the memory 270 and stores the image data therein (S14).

As such, the image data stored in the computer 25 may be displayed on a screen through a monitor (not shown) of the computer 25.

When all the image data stored in the memory 270 is output to the computer 25, the controller 280 of the door camera 23 erases the contents of the memory 270 so that the next captured image data can be stored. (S15).

In this way, a large number of visitors 1 are stored because the memory 270 of the small capacity door camera 23 stores the large amount of visitors 1 that cannot be stored when there are many visitors 1. You can save it.

In addition, the door camera 3 further includes a clock and stores the visit time information in the memory 70 when the image of the visitor 1 is photographed and stored, and is reproduced together when played by the user. Make sure you know the time you came.

As described above, in the embodiment of the present invention, a door camera system having a visitor recording function capable of returning home and confirming a visitor by recording a situation at the time when a visitor is absent can be provided, and a control method thereof.
