High Street and Brookdale Avenue is the city's fourth intersection to be monitored by the cameras, Oakland police said.
The cameras were installed Sept. 30, and warning notices will be mailed to red-light runners until Oct. 30.
After that, violators can expect to pay a fee and see a point added to their driving records. An Oakland Police Department staff member reviews and approves each citation, and a "Notice to Appear" is mailed to offenders.
Citations are issued for straight-through, left-turn and right-turn violations.
The automated cameras take four photos of the vehicle approaching, crossing and leaving the intersection, as well as a 12-second video. Copies of the photographs are sent in the mail, and videos can be viewed online at www.photonotice.com for 60 days from the date of the violation.
Eventually, 20 intersections in Oakland will have automated red-light cameras, police said.
