From Trump campaign signs to Planned Parenthood bumper stickers, license plate readers around the US are creating searchable databases that reveal Americans’ political leanings and more.

There are already 24 license plate readers installed in the San Fernando Valley, and the LAPD is hoping to have 100 up and running by the end of the year.

New automated license plate readers have appeared in Ballston. Multiple readers have contacted ARLnow in recent days about new tech installed on traffic signal poles along Fairfax Drive, at the intersections with N.

The ALPR cameras assist law enforcement in tracking and recording license plates as they pass through, to narrow the search for vehicles tied to crimes.

LOS ANGELES - License plate readers are up and running in the northwest San Fernando Valley, where police say they are already catching criminals . LAPD said a suspect wanted in a robbery targeting a 93-year-old man in a Costco parking lot was captured with the help of the license plate readers.

The license plate readers are being installed at various strategic locations in the northwestern part of the San Fernando Valley.

Councilman John Lee Lee says that since the effort began to install 100 readers in his district, they have already helped solve a pair of robberies.

Lee says his district is turning to technology to keep residents safe with 100 automated license plate readers going up in the San Fernando Valley, as there is a shortage of Los Angeles Police Department officers.

L.A. officials installed, for the first time, automated license plate readers in the San Fernando Valley’s Council District 12 to catch criminals involved in various crimes - they’re already delivering results.
