Hello Kul
In principle, the MOBOTIX LIVE APP supports any Dynamic DNS services such as DYNDNS.org or No-IP to connect to the camera remotely.
In the MOBOTIX LIVE APP, you only need to enter a public URL with the corresponding port to reach the camera externally. It is also important whether port 80 for http of the camera is passed through or port 443 for HTTPS.
The settings that have to be made in the MOBOTIX LIVE APP are well described in the following article.
Cameras are only addressed via the remote connection if the Live App has activated the Location “Abroad” mode (I would always choose this as the default mode even if the smartphone is in the local network for a short time to avoid switching).
A good approach from them was to test the corresponding remote URl in the browser first, if this works only the information in the Live App must be transferred correctly as described above.
If you are not using a typical Dyn DNS service but a service that implements the remote connection via a proxy, this is possible via a browser but is not supported by the Live App! In this case, switch to No-Ip.com, for example.
Here are a report to setup dyn dns in the MOBOTIX Cameras:
