Red-light photo camera activated in La Jolla City officials have launched three new red-light photo cameras to step up motorist and pedestrian safety, including cameras in the Midway area and La Jolla. The sensor-based cameras are now mounted on North Torrey Pines Road at Genesee Avenue in Torrey Pines and at Rosecrans Street at Nimitz Boulevard in the Roseville/Fleetridge neighborhood. They became active April 30, according to police. A third new camera has been activated at Balboa Avenue and Kearny Villa Road in Kearny Mesa, bringing the total number of red-light photo cameras across the city to 15. According to Monica Muñoz with the San Diego Police Department, motorists caught on camera running a red light will have a 30-day grace period, during which a warning citation will be issued. Beginning May 30, however, offenders caught on camera can expect to receive a citation with color photos of the violation and expect to pay a minimum $436 penalty. According to Muñoz, the systems are mounted on poles with sensors in front of an intersection. Once a light turns red, the system is activated and will recognize a vehicle that trips the sensors and travels across the limit line into the intersection.  She said the system snaps photos of the vehicle from the front and behind but is only designed to operate only after the signal has turned red.
