From Dahua Wiki
DDNS stands for Dynamic Domain Name System. The main advantage for DDNS is If you have a dynamic ip address, (where your address can change monthly by your ISP if not static) the DDNS service will track and update with your new IP address automatically. So no matter what your numeric IP address is, your DDNS address will work even if your numeric IP address changes.
