After a failed attempt with a not so much cheaper "budget camera" I switched to the safe bet K&F Concept. The network connection in the dry dock on the desk worked right away and didn't require any particularly deep IT knowledge.

It is comfortable to use, the app is stable, understandable and (in contrast to the budget app) inspires confidence in terms of security. The picture quality is perfect for the intended use.

The price is fair for what is offered.

I only have minor suggestions for improvement when it comes to assembly:
* Since the alignment is only possible in two superimposed axes (rotation, tilting), it is a bit fiddly to align the camera while standing on a ladder. If there were a mechanism that would allow the camera to rotate / tilt freely around all axes on a ball and then fix it with a clamping screw, that would easily be worth an additional 10 € to me.
* If the connection for the solar panel were on the bottom instead of on the back, plugging in the plug (standing on a ladder and not seeing the socket) would be quicker.
* The power switch could be a bit bigger to make it easier to operate (standing on a ladder).

But that's complaining at a high level, so 5 stars despite the small annoyances!
