1. What is DDNS
DNS: Domain Name System
To translate the numerical IP addresses like 220.127.116.11 into domain names, which can be easily memorized by humans like “milesight.org”.
DDNS: Dynamic DNS or DynDNS
To translate changing IP addresses into a constant domain name. This is used to provide a persistent domain name for a resource that may change address on the network.DDNS provider: ddns.milesight.com, dyndns.org, freedns.afraid.org, www.no-ip.com, www.zoneedit.com
2. How to Set DDNS
So far, Milesight cameras can support 5 DDNS servers.
Before using DDNS, you need to map HTTP Port and RTSP Port to External HTTP Port and External RTSP Port firstly. If you need to use the playback function via DDNS, you also need to map Playback Port to External Playback Port.
For more information about port forwarding, please refer to the troubleshooting:
It is recommended to enable UPnP, which will automatically map HTTP Port, RTSP Port and Playback Port to External HTTP Port, External RTSP Port and External Playback Port.
Note: If you want to use UPnP, the router needs to support UPnP function firstly.
