20130091272 | Network Connection Status Detection System and Method Thereof - A network connection status detection system and method thereof. The system comprises a network address translation (NAT) router, a server end and at least one network electronic device. The NAT router is a bridge for communicating an intranet with an extranet. The server end is disposed at the extranet and connected to the NAT router through a network. The network electronic device is disposed at the intranet and connected to the NAT router. When a channel is established between the network electronic device and the NAT router by executing a connection configuration so that the network electronic device connects to the server end, the network electronic device sends a connection detection signal to the server end. If the server end receives the connection detection signal and returns a confirmation signal, an indicator of the network electronic device will remind a user in a predetermined way. | 04-11-2013 |
20120162417 | SECURITY CONTROL SYSTEM AND METHOD THEREOF, COMPUTER READABLE MEDIA AND COMPUTER READABLE PROGRAM PRODUCT - The present invention discloses a security surveillance system and a method thereof, a computer readable storage media and a computer program product. The security surveillance system comprises a surveillance host and an electrical apparatus. The surveillance host could send a monitoring data of a period of a first event occurs to the electrical apparatus through the network when the first event occurs. While the electrical apparatus is playing the monitoring data and a second event occurs, the electrical apparatus switches directly to play the real-time monitoring data corresponding to the second event sent from the surveillance host, so as to achieve the purpose of grasping the site situation immediately. | 06-28-2012 |
