What are the difference between DMIP and DDNS? FAQ - DDNS \n\nApr. 20, 2005\n\nQ: What are the difference between DMIP and DDNS? \n\nA: \n\nDMIP utilizes standard File Transfer Protocol (FTP) to upload Ip address to a designated file server. This allows IP address of the GV System to be transferred to the file server periodically. You can now logon to the file server instead of GV System, file server will further redirect WebCam viewer to the GV-System.\n\n\nWhat is Dynamic DNS (DDNS)? \n\nThe Dynamic DNS is a small application that allows GeoVision user to register a domain name that always points to their GV-System. The DNS Client will update GV-System's IP address to DNS server every 10 minutes. Therefore, even if you are using dynamic IP, you can still locate your GV-System by using the registered domain name. \n\nDynamic DNS supports Windows 2000, XP and Server 2003 only . DNS Client will not support Windows 95/98 or ME. \n\nDynamic DNS uses port: 80 to upload IP address over the Internet. If your GV-System is connected behind a router or firewall, please make sure port: 80 are open. Dynamic DNS will only upload Global IP addresses. If your GV-System is using virtual IP port mapping should be done first. \n\n\n\nIn conclusion, for the DMIP usage, you need either build up a file server or use Geovision file server to upload your IP address and then find your IP in the list to make a connection. On the other hand, the Dynamic DNS is for a user who can register a domain name and which allows clients connect to the GV-system without complex steps. Therefore, we strongly recommand customers to use Dynamic DNS for further connection between GV-system and client PC. \n
