Hi, I got a 4G PTZ from Dahua and I can get the camera to pick up a 4G signal on multiple providers (its a world sim) however the camera does not connect to the P2P platform. Has anyone got any experience with these? I have a friend who dealt with their mobile 4G recorders a few years back and it turned out that P2P only worked when using DSS Pro as the P2P platform. I am wondering if this is the case with this camera? Dahua are not much help in this case. The hardware in the camera is a Huawei 4G module which should work in Europe, so I am ruling it out to be a hardware/regional issue. The camera is on the latest SD Prometheus firmware 2020-06-08.
