Calgary police are going ahead with a plan to outfit officers with body cameras and say they have become an effective policing tool.

A pilot project was started in November 2012 and 50 of the cameras were given to a variety of units within the Calgary Police Service to try out.

The micro-cameras are activated when officers respond to a call or come across an incident requiring investigation.

So far, the cameras have captured about 2700 videos including footage of intoxicated persons, assaults, traffic offences, impaired driving, homicide investigations and flood related duties this summer.

The footage can be stored for at least 13 months and up to 25 years depending on the investigation.

Police say that in some cases the videos have led to early case resolutions and convictions.

The police service will expand the program in a phased in approach.
