The Holyoke Police Department participates in Amazon’s "Ring network," which as reported in The Verge, "lets law enforcement ask users for footage from their Ring security cameras to assist with investigations." The Ring is an Amazon-produced "video doorbell, which allows Ring users to see, talk to, and record people who come to their doorsteps," and which "sends notifications to a person’s phone every time the doorbell rings or motion near the door is detected."
