ONVIF integration grey flickering

Hi everyone,

I have integrated my Lupus LE228 via ONVIF (since there is no Lupus camera integration unfortunately) and it is working fine. However when the stream on my dashboard is going live after the first five seconds it start to grey out the picture. This happens sometimes every second and sometimes every 30 minutes. Since I have the camera dashboard open on an iPad right next to me when working from home this get’s quite annoying. Interestingly this could only be oberstes on the old iPad Air and not when loading the stream on any other mobile device.

This is how the stream looks usually

And this is when it grey out.

The grey picture is there only for a second or so and then switches back to the normal stream again.

Maybe someone has an idea what the issue could be.
