There are 3 categories relevant here:
- manually adjustment of focus
- automatic adjustment of focus but no optical zoom
- automatic adjustment of focus AND optical zoom
If you want the focus to be automatically adjusted, you can get a camera that does so and not pay for optical zoom.
Stepping back, though, the issue with vibration will be primarily about the image shaking (as the whole camera moves) rather than simply it getting out of focus.
Stepping back further, do you have a preferred camera choice right now? What have you been looking at?
I fetched an Axis P-3353 not long back that's a real trooper, I think its got almost everything you want, (the angle only goes as wide as 105, not 107), as for the price though, ouch, it'l take the mustard off the hotdog as we say round here...

107 degrees will be the most difficult specification to meet in a motorized zoom camera (or even just an auto-focus camera). Most camera in this class will have lenses in the 3-12mm range and will give an H FOV of 80 degrees or so. The Axis camera that Jim mentions above with its 2.5mm @ F1.2 would meet your requirements almost perfectly (and maybe price doesn't matter so much when the offering is so unique! :-) )

Hikvision seems to be making good cameras, we started using them a lot last September and have good luck with them, they have this DS-2CD7254FWD-EIZ(H)(S), 2.7 ~ 9 mm @F1.6, angle of view: 101° ~ 30.4° (not quite 107) I have not used this particular model but I have used the bullet version that has very similar specifications DS-2CD8254FWD-EIZ. I dont know how true their claims are to 120 dB WDR but it seems to preform well. Price point is reasonable too.
Both Axis and Hikvision are good options, either way your customer would probably be happy with them.
Long and short of it is, a camera with auto back-focus should suffice, since it will address the "expected" need to tweak focus from time to time, while zoom really isn't something you'll need to alter on an ongoing basis. It's a feature that's built into the camera body, so you then have an option of which lens to use to get the view you want, rather than something that's part of the lens and thus usually means a combined camera/lens unit.
The catch is, you do have to make sure it can be triggered remotely... which SHOULDN'T be an issue with most IP cameras, although with an analog camera it would require a separate RS-485 connection. There may actually be a few older IP cameras floating around that only support control via RS-485 as well, so it's best to be sure in advance, because that's not something you want to learn AFTER everything is purchased ad installed.
It's not clear whether the expected problem with vibration is image shake, or the idea that focus may drift because of it... if the zoom, focus and backfocus are properly locked down on a standard varifocal lens, there should be no change due to vibration. If image stability is the concern, none of these particular options (remote zoom, remote focus, ABF) do anything to address vibration or camera shake. For that you need some form of image stabilization, which is a whole other realm.
