9. What is DDNS? Is it important for IP surveillance product to have DDNS support?
DDNS is an acronym for Dynamic Domain Name Service. It is important to choose an IP
network camera that has DDNS support for dynamic IP addresses.
Chances are that the network has a dynamic IP address (which changes with every log on). A
DDNS service makes sure that the camera‟s IP address always matches up to the current
server address. DDNS also allows for a website to be linked to the IP camera that is
constantly updated with the correct information and has a reliable feed.

The GXV3501/3601/3504 all use the H.264 video codec. Windows Media Player may lack
