The Raids Online crime map for Cambridge showed many recent crimes Tuesday, but no violent crimes.

Cambridge Police have rolled out another way for residents with computers and smartphones to keep up on local crime.

Already online with Citizen Observer for neighborhood-based crime alerts, CodeRed for use in emergencies, “automated” tweets and the BridgeStat monthly crime analysis, as of Tuesday the department offers a free online crime map called Raids Online.

Residents can use the system, by Bair Analytics, to see a map of the city overlaid with incidents broken down by type – such as residential, auto or other kinds of theft – and change or limit what’s seen by date and incident type, as well as search by address. The system automatically syncs with the department’s records system to keep crime information updated.

The system also allows residents to sign up for neighborhood watch e-mails that include a breakdown of recent crime activity and submit an anonymous tip about a crime.

“I think this is a really innovative way to share crime information with the community,” City Manager Richard C. Rossi said in a press release. “Many police departments produce crime reports, but this new map allows Cambridge residents to see, on a daily basis, where, when and what types of crimes police are responding to in their neighborhoods.”

Crime in other communities using the system can also be seen – not Somerville, but Malden, for instance.
