License plate readers in Somerville, MA
Volunteers have documented 12 automated license plate readers inside Somerville. That is the 22nd-largest total among the 29 Massachusetts cities indexed here, and 1.0% of the statewide total. At 2.9 per square mile it is more densely covered than 73% of the 2,395 US cities indexed nationally. No manufacturer was recorded for 67% 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. Where a mount was recorded, volunteers logged 8 on walls and 2 on poles.

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.
