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 IPaddress. If so, the DDNS will update GV-System’s IP address to DNS Server in 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, and Windows Server 2003 only, but not supports Windows 95/98 or ME. Dynamic DNS uploads IP address over the Internet through ports 80 and 81. Ifyour GV-System is connected behind a router or firewall, make sure ports 80 and 81 are open. 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 windowappears. 2. Select the Install V 8.0.0.0 System item. 3. Select Dynamic DNS Service, and follow the on-screen instructions.

Username: The username you registered. In this example the username is“dynamicdns” Hostname: The hostname you created. Hostname is made by registered username and

“dipmap.com”. In this example the host name is “ http://dynamicdns.dipmap.com ”. This will be the domain name you use for login to GV-System. IP Address: Your GV-System’s current IP address. This IP address will be updated every 10 minutes. In the DNS Client dialog box, enter the registered username andpassword, and then press the Save button. The system will show the connection information as illustrated below. The DNS Client program is now activated. However, it will not upload IP address unless one of the following applications is running: the Main System, Center V2, VSM, Dispatch Server, Twin DVR, and SMS Server. If the IP address of your GV-System is not updated for more than 30 days, yourhost name will be deleted automatically. Check Run at startup if you wish to auto run Dynamic DNS AP on the next Windows start-up.

TwinDVR System
TwinServer is an external application that helps sharing the networking liability from the GV-System. A complete TwinServer concept requires at least two computers: a TwinServer, whichshould be run on the computer where GV-System is installed, and a TwinDVR, which should be run on a separate computer connected to the same LAN as the TwinServer. The TwinServer sends video stream to TwinDVR, while TwinDVR acts as a WebCam Server and serves all WebCam clients over the Internet. One TwinDVR can serve approximately 200 channels over the Internet. Multiple TwinDVRs can be added to...
