DDNS (Dynamic Domain Name System) is a system that monitors changes in the user's IP Address. Most small
business or residential users have a dynamic IP address that can change periodically. When the IP address changes
any devices that were using that older IP address will be unable to connect to the DVR. When DDNS is setup,
the DVR will detect changes in the IP address and send that new info to the DDNS service. The DDNS service
will update the IP address (numbers) but the Host Name will remain unchanged, allowing uninterrupted remote
connection to the DVR.
