I see that some of these cameras (specifically some of the bullet or
torpedo type) claim to be "varifocal".

A specific example is the CVC-7706DNV:

Note the link "how to adjust the verifocal lens" :

It's really a focus adjustment.

I believe a true varifocal lens is a lens that changes it's focus when
the focal length is changed. Which means the lens must be some sort
of zoom lens. So does the CVC-7706DNV (or any other "varifocal"
camera) have some sort of external ring or control that allows you to
change it's focal length (ie zoom in or out) ???
