Baltimore County police have placed speed cameras outside six schools in an effort to crack down on reckless drivers that had netted nearly $9 million as of last year.
The county has not bought new cameras, police spokesman Cpl. John Wachter said, but moved them from other sites. Wachter declined to reveal the previous locations.
The cameras were placed outside Deer Park Elementary School in Owings Mills, Reisterstown Elementary School, Calvert Hall College High School in Towson, Timonium Elementary School, McCormick Elementary School in Overlea and General John Stricker Middle School in Dundalk.
Drivers will receive warnings for about a month after the cameras begin recording, police said. Then they will get tickets.
Officials say the cameras pay for themselves. The county had netted $8.75 million as of last year. The money is spent on school security and public safety, officials said.
Officials in Baltimore City have struggled to launch a reliable speed camera program.
City officials announced plans last month to revive a defunct red light and speed camera system. They issued a request for bids for 10 red light cameras, 10 fixed speed cameras and 10 portable systems.
City Transportation Director William Johnson has said the new program will include safeguards to ensure the integrity of the tickets issued.
It would be the city's third program after two attempts in which motorists received tickets in error. The system, which was run for years by Xerox State & Local Solutions and briefly by Brekford Corp., was shut down in April 2013.
At its height, the city's speed camera system had 83 locations and brought in nearly $20 million a year. But a Baltimore Sun investigation revealed problems, including tickets issued to stopped or slow-moving cars.
No pedestrians were injured by vehicles in city school zones in 2012 or 2013, according to state data.
Officials turned the cameras off in 2013. They have not been turned on since.
