The cameras can scan license plates and other characters of any vehicle, but not people or their faces.
The system then can check national and local criminal databases, and alert law enforcement in real-time if it's needed.
Fulton County Superintendent Dr. Mike Looney said this will help keep his district on the cutting edge of student safety.
"I think we're on the leading edge of focusing on safety," Looney said. "Of course, we can't give everybody the assurance that nothing will happen. But I can assure you that we're preparing for the potential of something happening and doing everything that we know to do proactively."
The cameras will cost the district roughly $626,300 paid for by ESPLOST funds. The district plans to immediately begin installation with the hope all schools could have Flock cameras by January.
Looney also said the board has authorized an additional $6 million in their current fiscal year for the purpose of enhancing safety measures further.
"As time has gone by, we continue to see tragedy happen on school campuses around the country and we are absolutely determined, I as the superintendent and the school board as the governance team, is determined to do everything that we practically can to make sure that our students, staff and school visitors are safe at all times," he said.
