Police officers across Causeway Coast and Glens District will be using body worn video cameras when they are on duty from now on.
The measure came into effect on Monday.
Superintendent Jeremy Lindsay said: “The pilot of this technology in Derry City and Strabane evidenced how body worn video has the potential to improve the quality of evidence provided by police officers and thereby increase the number of offenders brought to justice.
“Video evidence provides a compelling account of events and enables the raw emotion and action from a scene to be replayed in the courts in a manner that could never be captured in a witness statement.
“It also supports accountability and transparency, both of which are key elements in increasing public confidence in policing.”
Alderman William King, chair of the Policing and Community Safety Partnership, said the PCSP supports “any initiative that enhances community safety and encourages trust and confidence in community policing”.`
