A CCTV camera has been installed in part of Surrey where people have "suffered years of low-level crime and anti-social behaviour", a council said.
Cash set aside from the jail development paid for the camera
The camera, near Bronzefield Prison in Ashford, has been paid for with money set aside from development of the prison to improve public safety.
In the most recent incident, youths were seen near the prison with an air rifle, according to Spelthorne council.
The camera is on the junction of Woodthorpe Road and Chesterfield Road.
Councillor Richard Smith-Ainsley said the camera was monitored 24 hours a day, seven days a week.
Pc Vic Smith said it would "help considerably with the policing of the area".
He said: "Already it is proving its worth.
"Those people who behave in an anti-social way or commit crime can now expect to be identified and dealt with."
The council said the camera had clear views of Woodthorpe Road, Chesterfield Road, the green outside the prison, and the footbridge across the railway line.
