Vision system on HACCP plan

Does a vision system used on production of plastic containers need to be on the HACCP plan?

I doubt that you could use it as a CCP, since you'd need upper and lower control limits, but I don't see where mentioning it as maybe a cp would work.

Can you be more specific on the measurements performed by your vision system? Which parameters does your vision system monitor?

There are highly complex vision systems in the market that measure parameters which can be considered CCP under certain circumstances.
