Despite serving as an important line of communication during violent incidents or big snow events, like last week’s “bomb cyclone,” most of the city’s households are not signed up for the Cambridge Alert Network.
The Cambridge Alert Network is a system of various services including Citizen Observer (tip411), NextDoor and CodeRED. The network sends residents — through text, email or phone — crucial notifications relating to weather, crime, safety, and any other emergency situations.
Citizen Observer (tip411)
As a subscription-based service, Citizen Observer (tip411), a branch of the Alert Network, allows residents to sign up for citywide information on crime for each of the 13 neighborhoods in Cambridge. According to Jeremy Warnick, Cambridge Police Department’s director of communications and media relations, these notifications reach approximately 22,000 subscribers citywide: less than 20 percent of the city’s population.
″[Citizen Observer] is really helpful, particularly with an ongoing criminal manner in which we will provide updates,” Warnick said. “The other component of it is that it also allows us to receive anonymous tips. [The tips] are encrypted so we have no idea who’s on the other side sending those in. It’s a trustworthy way of people submitting information that may help us with an investigation.”
Warnick said the department usually receives multiple crime tips a week through Citizen Observer, and that they often “come in waves.”

For Hamden Police, it is another step in helping to bridge the gap between police officers and the communities they protect. A new smartphone app called tip411 lets smartphone users submit crime tips anonymously. Click here to see the video of Chief Wydra talking about the value of tip411.
“Our mission is the preservation of public peace and order, the prevention and detection of crime, the apprehension of offenders, and the protection of persons and property,” said Stratford, CT Police Chief Joseph McNeil. “To achieve this goal, the department strives to gain and retain the confidence and respect of the public in such a way as to insure the welfare and betterment of the citizens of Stratford, and we believe our new app will help us better connect and engage with our residents.”
