Simply the presence of a camera invokes the most benefit in terms of discouraging criminal activity in the first place.

Additional benefits from investing in better resolution (and requisite storage costs) then begin to scale down sharply as cost increases. Let’s say you get 90% effectiveness from installing a low res camera system; the additional 10% will cost you 4x what you paid.

Low resolution is “good enough” for 99% of the use cases (simple avoidance).
