Police in El Cajon say the city's new license plate readers are showing some success in cracking down on crime. The implementation comes as the city of San Diego just approved license plate readers and smart street lights. There are forty license plate reading cameras throughout El Cajon.

The police department started training on how to use the technology over the past couple of weeks. The cameras have already shown success.
