I’m not sure if I understand the question? Is the question if such a camera exists - Yes!
The bulk of the ones sold on line are analog 700 ~ 1000 TVL. I am more interested in seeing a company release a 4 MP POE with low light performance in the same form factor. All of the pin hole camera's I've used and installed from Axis / Hikvision are still too large to deploy in tight spaces without some creative thinking / housing.Wow, was about to post that if it is Photoshopped then it's a good job as I can see a lens in the pic but now knowing that it's real, just Wow!

FYI the quality of them is terrible, but guess you have to say they are available.
