1080P still wins on volume and fleet tenders where price and card life come first. 2K is the default dual-channel tier: plates stay readable farther out without 4K file sizes. 4K belongs on hidden luxury and premium private-label lines — buyers already paid for the cover, so the sensor should match.
Most YEEROAD customers stock one 1080P universal, one 2K dual, plus a smaller run of 4K covers they actually install.
