3.1 Please apply a DDNS account the DVR supports. Here we take no-ip DDNS as an example. We go to www.no-ip.com to apple a DDNS account.
Notice: if your network's external IP is static, not dynamic, you don't need set up DDNS
4. Please use computer to go to the router's page to do port forwarding with camera's IP, http port and media port.
You can refer ?to the previous step 2.2 to find camera's IP，http port and media port.
You can get some help about how to do port forwarding here.
We will take our router as an example. The port forwarding setting?varies from different. Picture below is just for reference.
After you finish port forwarding, you can open?www.canyouseeme.org?to check if port is open.
Finally, if DDNS and port forwarding succeed, address like http: //annke2018.ddns.net:111 So that the device can be opened anywhere on any computer.
