IP FPV camera - Is there such a thing?

Has anyone found a small form factor IP based camera that can be used as an FPV feed?
With high power ip network bridging it would be great to have a couple of IP cameras onboard without the need for expensive/heavy HDMI to IP converters.

SIYI make a couple of different ones, I’m always on the lookout for smaller ones though

Thank you for the link that’s super useful.

Have you had much time to experiment with them?
Can you configure their IP and other network parameters fairly easily?

They are pretty huge abs heavy aren’t they. Wonder if it’s possible to remove the case and split the camera from the circuit boards a bit like the firefly split hd.
