(i.e. http://: , e.g. http://192.168.0.200:8000) to access the device withIP 192.168.0.200 and port with 8000).These features enable user to use the device behind NAT or IP Sharing devices which could accessup to 65536 NDC with one IP Address.• RTSP Port: The port on which the device will receive RTSP (streaming video) requests.• Apply: Click this button to save the changes made.– Dynamic DNS SettingsThe DDNS (Dynamic Domain Name Service) is used when users want to access the NDC with an easy memorizedname such as http://demo.ddns.pixord.com instead of http://61.220.235.172. This service could be useful when theNDC is located behind Dial-up ADSL or IP sharing devices, which does not have fix IP address, then it’s impossible toreach the NDC from Internet.When the NDC enables the DDNS service, it will “register” to the DDNS server with its information, such as servername to access, router virtual port number and updated frequency, etc.Then NDC automatically “update” to the DDNS server by a fix frequency, so even the IP is changed by ISP, the DDNSserver still could get and update internal database. Then, once users access from Internet with its register name, e.g. ifregistering with server name “demo” to DDNS server “ddns.pixord.com”, the NDC could be accessed byhttp://demo.ddns.pixord.com.50
