And in most cases, the ones at home improvement stores are the only ones in the city. Salem (the state capital) only has them at Lowes. Eugene is an exception with many cameras (including Home Depot and Lowe's).
I'd be interested in when these cameras were placed. If recent, I'd wonder about an ICE/immigration response.
Just zooming around the map, here's a handful of citys I've seen...
Lowe's: Albany, Salem, McMinville, Vancouver WA, Fairview, Eugene, Bend, Redmond, Medford
Home Depot: Sherwood, Hillsboro, Beaverton, Cedar Mill (Beaverton), Tigard, Vancouver WA, Portland (multiple), Gresham, Oregon City
