E. Setting up DDNS Function
If you set up your IP Camera with DHCP network, the IP address of your IP Camera may change at different
times for different reasons, particularly after a power failure. The changing IP address of the IP Camera
may cause you difficulties accessing the IP Camera. To solve this problem, you can set up the DDNS
function to your IP Camera, and access your IP Camera with a fixed host name whenever the IP address of
your IP Camera changes.
DDNS (Dynamic Domain Name System) is a service used to map a domain name to the dynamic IP address
of a network device. It assigns a domain name (URL) to the IP Camera, so that the user does not need to
go through the trouble of checking if the IP address assigned by DHCP Server has changed. Once the IP is
changed, the IP Camera will automatically update the information to the DDNS to ensure it is always
available for remote access.
To set up DDNS for your IP Camera, you have to 1) enable the DMZ or Port Forwarding function of your
router 2) configure the network setting of your IP Camera 3) configure the DDNS setting of your IP Camera.
Please follow the steps below.
