180 degree horizontal field of view?

The widest I've seen are 120 degree like the Foscam C2

I've got a Foscam C1-lite, which is the older model of the C2. The "lite" doesn't have IR, which won't go through glass well anyway, but that means the front is more or less flat, and sets well against the window. Its super cheap, though the recordings have caused problems playing back in SS.
It's about 110 degree FOVs. It's unlikely you'll find anything wider without spending a lot for something very specialised - remember that wider field of view means lower angular resolution, increased distortion, and much more complex optics. -
I know there are lots of cameras now that provide 180 degree coverage like Hikvision DS-2CD63C5G0-I(V)(S), Axis Communications P3717-PLE, Dahua IPC-EBW81230, etc. But choosing one of them is difficult. And i am also not aware of all other cameras.
So, may you please suggest me some good camera with 180 degree?

The Hikvision DS-2CD63C5G0-I is a single-sensor fisheye camera with a 180° view both horizontal and vertical. So it can be mounted in the middle of a ceiling to view the whole room.
The Axis P3717-PLE (and newer model P3727-PLE) is a quad-sensor camera where each sensor will output its own rectilinear (non-fisheye) image. Again, this would work well in the middle of the ceiling to view the whole room.
An alternative, if you want just 180° horizontal, is something like the Dahua IPC-PF83230-A180, which is a multi-sensor camera that stitches its images from each sensor together to output a single wide view. This is good for wall mount.
Hikvision, Dahua and Axis are all good manufacturers with a range of nice camera models on offer.
Note that cameras should be mounted properly on walls or ceiling or under eaves etc - not pressed up against a window, as the image quality will suffer significantly if you try this.

I installed a Reolink Duo 2 PoE over lunch today. It thus far (in the two hours since install) works well and gives 180 degree horizontal coverage, but it wouldn't work up against glass as you describe unless you made a hood that would go around it to mate up with the window to avoid reflections (a few pieces of black cardboard and gaff tape would probably work, of you could 3d print something.) No matter what you do, you'd have difficulty with reflections from the night illuminators, but you could probably get daytime reflections down to almost nothing. I don't know what the vertical coverage is, degree-wise. This is two sensors stitched together, and it looks pretty decent. Highest resolution is 4608x1728. It has decent audio for listening, though I don't think it will work with SS outbound audio. Also has IR and white light illumination, vehicle and person detection (not that I use it.) Cost on Amazon was $135 USD.
Everything with a wide angle is going to produce some warping, especially if the view is from above & down as most cameras are. There is this thread (https://bensoftware.com/forum/discussion/367/panoramic-fisheye-360-degree-cameras-and-securityspy#latest) asking about server-side de-warping, but that would also probably imply virtual cameras and a challenging UI to define "unwarped" views. It would still be pretty sweet to have that ability, since this would reduce the number of physical cameras I needed significantly if these Reolinks continue to work out.
The view here is along a straight wall (shipping container is part of the "wall" and so this might even be a bit more than 180 degrees. The "split" between the sensors is in the middle of the frame, and you can fine-adjust it horiz./vert. but I couldn't really see the seam so I haven't meddled with it.
