Brent police have successfully trialled the Body-Worn Video (BWV) camera pilot, along with other boroughs in London.
The BWV pilot involved 40% of patrolling officers in Brent wearing the cameras for six months.
The camera is always passively recording but the officer can press a button at any time to start active recording.
When the button is pressed, the camera starts recording but also includes the last 30 seconds prior to the button being pressed.
At the end of their shift, officers dock the cameras and the footage is uploaded to cloud storage.
Brent Borough Commander, Mickey Gallagher, said: "The pilot has concluded with all of the other sites across London having compared their thoughts on the best use of BWV.
“There are lots of good news stories and prosecutions that would not have been possible without BWV.”
The introduction of the body-worn cameras is a significant purchase, with 20,000 needed along with associated software and hardware.
