So the device should require very specific license plates to scan for—not the current dragnet. The software should only "ping" when there is a confident match with said license plate(s)—and merely log which license plate, time stamp a single photo, and note the confidence level of it being a match.
The frame buffer should be the only place (a frame of) video is ever stored at all (excepting the high-confidence match indicated above).
The only issue remaining would be whether we trust the device/software to have complied (and not have a backdoor) and of course there needs to be a legal warrant for every license plate uploaded (and it should expire fairly frequently, likely requiring a new warrant to continue canning for the plate).
