I've not used that metric before, but after a little research it seems 60-80 ppf is a target number.
A little background, my usecase is not for automation of tag reading, just want to be able to make out tags in off chance its needed.
Any camera that can do this with a 2.8 mm lens/no zoom?
Nice to haves:
Varfocil.
PTZ.
Also two other related questions:
1. Any info on why IP cameras are so far behind the curve when it comes to using the latest image sensor tech?
2. I noticed the below image, is this tool available...
