Croydon Council brought in the camera following residents’ concerns about antisocial behaviour and safety in the park.
There is also a permanent camera at the Fell Road entrance to the gardens.
Cabinet member for communities, safety and justice, Councillor Hamida Ali, said: “We want everyone to be able to enjoy The Queen’s Gardens but unfortunately the behaviour by a small minority is making people feel uncomfortable and unsafe, which we are determined to address.
“The camera will help us, in partnership with the police, tackle anti-social behaviour. We want to keep people safe and ensure that The Queen’s Gardens is a place everyone enjoys.”
The new camera is one of 10 that have been deployed around the borough (initially for three months) to boost the council and police’s ability to respond to problems in areas not covered by the existing fixed CCTV network.
The cameras are currently deployed at locations around the town centre including High Street, Katharine Street, North End, Poplar Walk and Surrey Street, as well as in Brook Road, Thornton Heath; Broom Road, Shirley; Green Lane, Norbury and Oakfield Road, Broad Green.
