I have a Nevue Sentry 2 camera, and it works fine. The camera is connected to the WIFI.
I have turned on the motion detection.
If my phone is connected to the same WIFI as the camera, I correctly get the notification on my mobilephone
Buf if my mobilephone is connected to a mobile network (4G), i got no notifications. I have to open the application to see the alerts and photos.
Do i have to configure something on the camera ? On my router ? On my phone ?
