8. 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 a website to be linked to
the IP camera that is constantly updated with the correct information and has a reliable feed.
