Safer Birmingham Partnership, a joint partnership between West Midlands Police and Birmingham City Council, has deployed technology which can detect gun shot fire from up to two kilometres away within a 25-metre radius.
West Midlands Police said the sensors had been placed high up on buildings in north-west areas of the city.
The operation is designed to combat gun-related crime in the north-west of the City and uses communications technology designed by US based firm Shotspotter.
Birmingham will be the first city in the UK to implement this system.
The ShotSpotter patented technology uses the physics of sound propagation and triangulation to determine the precise location where the sound originated. The sound is then processed using Audio analytics.
The system has already been used for a number of years across America and has played a significant role in reducing gun crime and apprehending offenders.
Chris McKeogh, chief superintendant of West Midlands Police, said the technology will enable the force to deploy officers more effective to crime scenes,
"It will tell us how many firearms have been discharged prior to officers arriving at the scene, which enables us to maximise the safety of our officers and the public," he said.
