Security staff at 15 pubs and clubs in Glasgow are to be issued with body-worn security cameras in a bid to reduce alcohol-related violence.
The equipment consists of a small camera which relays images to a jacket-mounted screen. This allows the person being filmed to see their image.
Strathclyde Police said use of the cameras in other areas of the UK had seen a significant drop in violence.
The pilot project will run in Glasgow until 6 January.
The results will then be evaluated by police to determine if the cameras will be used in the long term.
The idea for using the technology in Glasgow was put forward by crime prevention officer Ch Insp George Nedley, following discussions with the security industry last month.
He contacted National Door Watch which offered to provide the cameras free of charge.
Several stewarding companies, who look after venues in the city, have volunteered to issue the kit to their staff.
Assistant Chief Constable Campbell Corrigan said the initiative would hopefully make the city centre safer.
"Everyone should be able to go out and enjoy themselves responsibly, and this pilot scheme, in some of our most popular bars and clubs, will help us achieve our aim of reducing alcohol related violence, ensuring that everyone can enjoy Glasgow city centre at night and at the weekend," he said.
The venues taking part in the pilot are Karbon, Campus, Tunnel, The Garage, Play, Kushion, The Polo Lounge, Common, O'Couture, Cathouse, Princess Gala Casino, Jumpin Jax, Savoy, Victoria's and Society Rooms.
The pilot will use body-worn cameras supplied by four different companies - Edesix, Eyewitness PC, Reveal Media and Robocam.
