Useful Utilities
This chapter discusses some advanced level features and utilities that could help administrator to
maximize system performance in a security network.
Dynamic DNS
The Dynamic DNS is an application that allows users to register domain names that always point to
their GV-Systems. This application is only necessary when your GV-System is using a dynamic IP
address. If so, the DDNS will update GV-System’s IP address to DNS Server every 10 minutes.
Therefore, even if your GV-System’s IP address changes, you can still locate it by using the registered
domain name.
Dynamic DNS supports Windows XP, Windows 2000, Windows Server 2003 and Windows Vista, but it
does not support Windows 95/98 or ME.
Dynamic DNS uploads IP addresses over the Internet through ports 80 and 81. If your GV-System is
connected behind a router or firewall, make sure ports 80 and 81 are enabled. Dynamic DNS will only
upload global IP addresses. If your GV-System is using virtual IP, NAT port mapping should be done
first.
Installing Dynamic DNS
To install Dynamic DNS, follow these steps:
1. Insert the Surveillance System Software CD to your PC. It will automatically run, and a window
appears.
2. Select the Install V 8.2.0.0 System item.
3. Select Dynamic DNS Service, and follow the on-screen instructions.
