SERVER, SYSTEM, AND CONTROL METHOD FOR MONITORING REMOTE IMAGE

摘要

PURPOSE: A server for remote image monitoring, a system thereof, and a control method thereof are provided to perform efficient communications between devices which use a private Internet protocol (IP) based on minimum information. CONSTITUTION: A monitoring device (210) receives an image which is photographed in a photographing device. A relaying server (100) determines a communications method between the photographing device and the monitoring device. Network address translation (NAT) groups transmit a public IP and a port number which is respectively corresponded to the photographing device and the monitoring device to the relaying server. The relaying server receives a communications method validation request signal of the photographing device and the monitoring device via the NAT group. The relaying server determines communications method for remote image monitoring between the photographing device and the monitoring device based on the public IP and the port number which is included in the received communications method validation request signal.
