Why to use 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.

To enable the DDNS function:
1. In order to allow remote access to the IP Camera from outside of the local network, enable either the Port
or DMZ function of your router. Please refer to the manual of your router for more details.

Note: If you enable the Port Forwarding of your router, the Enable UPnP Port Forwarding function must be enabled on the IP camera (see Port Settings field in the Step 2 image).

2. On the Network Setting page (Setting > System Settings > Network > IP Settings), configure the IP Settings, keep the default Port    Settings and then click the Apply button.


  • If Static IP is selected: Enter the IP address, subnet mask, default gateway and the DNS Server 1. Please consult with your ISP service provider for the information of subnet mask, default gateway and the DNS Server 1.
  • If DHCP is selected: The IP address, subnet mask, default gateway and the DNS Server 1 will be assigned automatically by DHCP server.
  • If PPPoE is selected: Enter the User Name (e.g. and Password provided by your ISP service provider.

3. In the DDNS Settings field (Setting > System Settings > Network > DDNS Settings), register a free host name from
EverFocus DDNS and then click the Apply button.

a. Check Enable Service ISP to enable the DDNS function.
b. Select and enter a desired host name in the IP Camera Name field. If the host name is
available, a “Success” window will appear. Click OK. If not, try another host name until the “Success” window appears.

Note: The host name should not include a space, or a dot (period) or any special characters particularly _~ ! @ # $ % ^ & * ( ) + < > " ; : . ,

c. Click Apply.

4. The DDNS setup is now complete. Open a browser and enter the domain name
(http://[host name] in the address field. The Web interface of the IP Camera should be
displayed. For example, if you’ve obtained the host name “HQtest” from EverFocus DDNS server, enter in the address field of the browser.
