I have noticed that a number of members here recommend minimum PPF recommendations of 100+ I am curious what others recommend?
The upside of 100+ ppf is that it gives a significant margin of error for harsh lighting or low light or poor lens quality, etc. The downside is that it forces constraints in horizontal FoV, e.g., 1080p at 100+ ppf is ~20' max, 4MP at 100+ ppf is ~27' max. In smaller indoor areas, that can often work but larger areas, longer hallways and outdoor areas can be pretty difficult to meet 100+ ppf.
As a point of reference, for the ~150,000 cameras saved in the IPVM calculator, the average is ~60 ppf. I am not saying any one value is 'right' but in practice it seems that ppf is often sacrificed given constraints on coverage width, camera count, etc.
So curious what PPF targets you aim for? And also how often, or ever, you go below those targets?
