License plate readers in Somerville, MA
Volunteers have documented 13 automated license plate readers inside Somerville. That is the 22nd-largest total among the 30 Massachusetts cities indexed here, and 1.1% of the statewide total. At 3.2 per square mile it is more densely covered than 76% of the 2,400 US cities indexed nationally. No manufacturer was recorded for 62% of them, so the vendor mix here is less certain than the count. Volunteers also recorded non-government operators here, including The Home Depot and Home Depot.

They are evidence of where cameras have been seen — not a complete or official inventory, and cameras may have been added or removed since documentation.
