What current IP cameras have changeable (e.g. Set screw, not epoxy mounted) Lenses

[SeventyPlus]

Cameras I've bought recently all had lenses secured with epoxy. The standard 2.8 and 3.6 lenses show everything, but see nothing. Yes, there are inexpensive zoon and varifocal lenses, but they don't seem to provide the range they claim. Probably because focusing changes the effective focal length. (e.g. 5x 2.8-12mm seem to only provide a 2x range), so I can't get the coverage and magnification I need.

Anyone know of fixed lens cameras with lenses that can actually be changed by loosening a set screw or?

Thanks in advance for any suggestions
