VLP Model Numbers
Model: VLP-32-C-A
Model: VLP-32-C
These are all the same hardware model (A). You might see a "-B" or rev B unit in the field, but the B units run on an entirely different FW revision.
we added the -A when we changed the color of the ring lens
when they sensor comes in for a repair and they have an old green lens and we change it to blue we do not add the A on the part number. So now its hard to know which lens they have unless we ask or it comes in (edited)
