Abstract: A plug and play network system, a plug and play network video recorder, and its control method. The network system comprises a remote browser device, a plurality of slave devices and a master device. When the slave devices are connected to the master device, each slave device can obtain its own IP address from a dynamic host configuration protocol unit disposed in the master device. Meanwhile, the master device can obtain the universal plug and play signal from each universal plug and play unit disposed in the slave devices. Thus, each signal capturing unit disposed in the slave devices can actively transmit the captured signal to the data processing unit in the master device. The data processing unit processes and transmits the captured signal to a remote browser device. The remote browser device displays the captured signal on the different sections of the screen thereof.

Abstract: 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.
