8. Whether the civil rights and liberties of any communities or groups, including communities of
color or other marginalized communities in the city are disproportionately impacted by the
deployment of the surveillance technology:
Cameras monitor Fire Department critical infrastructure (fire stations). Cameras are on city roads
and directed at fires stations, they are not positioned on any other basis. Login procedures and
recording authorization will track users and ensure all use and recordings are for approved criminal
or traffic investigation. Any movement of fixed cameras is required to be reported to the BOEM and
will only be moved for a legitimate law enforcement or emergency reason.
The Somerville Police have a Bias Based Policing Policy (#115). This policy emphasizes the
Department’s commitment to protecting the Constitutional and civil rights of its citizens. Any misuse
of these cameras to police prejudicially would be a violation of department policy. Any movement of
cameras for an investigative reason would have to be approved by a detective supervisor.
9. A disclosure of any new agreements made in the past 12 months with non-city entities that may
include acquiring, sharing, or otherwise using surveillance technology or the surveillance data it
