Below is a response from Granby Police Chief Carl Rosensweig regarding the license plate reader along with a link to a Canton Patch article.
Information is available if you ask.
“Thank you for your question. The vehicle I believe you refer to is a regional initiative between the nine north central communities. The Patch ran a very good article describing the vehicle. I've included a link to the patch article. “
