Recommendation PoE Dome Camera with mounting "from above"

Hello forum,

I am currently looking for dome cameras for surveillance. The camera must be PoE capable and pan-tilt. The camera should be mounted on the roof overhang, which I can easily access from above, that is, from the attic, and I can also drill from above. Ideally, the camera should be one that can be inserted and mounted from above. Preferably also with a special bracket.
I had seen such a bracket with the UniFi UVC-G3 (Low-Profile In-Ceiling Mount). Unfortunately, this camera cannot look directly downwards.

Do you have any ideas or recommendations?

turm dot tech IP PTZ cameras ... if you find something suitable there, I can gladly give you real HEK prices because the catalog prices are a bit utopian
