And a server 30 for receiving the image data and transmitting the received image data to the image output unit 20 when the image output unit 20 requests the image data.

The image acquisition unit 10 may include a camera 11 for capturing a predetermined space, an image data storage unit 12 in which image data captured by the camera 11 is compressed and stored, and the image data storage unit. And a first communication module 13 for transmitting the image data stored in (12) to the outside via wireless communication.

In particular, the video data storage unit 12 uses a digital video recorder (hereinafter referred to as a DVR), which is a video tape of a conventional video cassette recorder (hereinafter referred to as a VCR). If you repeat the recording several times by using, you can solve the trouble such as deterioration of the video tape and replacement of the video tape. In addition, since the image data is stored as a digital signal, it is possible to compress and store the image data to one hundredth by using MPEG-4, which is a moving image compression standard.

In addition, the first communication module 13 transmits the image data at the time when the image data is compressed and stored to the image data storage unit 12 to the outside, so that the image data captured by the camera 11 is in real time. It can be transmitted to the outside through the first communication module (13).

On the other hand, the image output unit 20 is connected to the navigation including a liquid crystal screen installed in the vehicle, the image data received from the image acquisition unit 10 receives the image data so that the driver can check the image data Displayed on the LCD screen.

The image output unit 20 receives the second communication module 21 receiving the image data transmitted from the image acquisition unit 10 and the image data received by the second communication module 21. The control unit 22 for processing the received image data, and the decoder unit 23 for decoding the received image data under the control of the control unit 22 so that the image data can be displayed through the liquid crystal screen It is configured to include.
