Download osm data, extract roads and surveillance, gpd overlay how=difference, remove/edit the different osmid's, write to pbf file, convert to obf file w/ osmandmapcreator, import into OsmAnd.

Edit: link https://github.com/pickpj/Big-B-Router - I tend to find ALPRs that are missing in the OSM data, so keep on updating OSM data.
