Stores installing cameras with license-plate readers in effort to combat retail theft

There is controversy surrounding a new crime prevention technology being used outside stores, including Home Depot and Lowe's.

The companies are installing special cameras in some parking lots that are equipped with automated license-plate readers.

The goal is to boost safety and more easily track down any thieves.

It's not yet known exactly which locations will have the cameras.

This comes after a string of crimes at Home Depot stores, including a theft ring that targeted stores in four Philadelphia-area counties last year.

However, civil rights groups are raising concerns about privacy rights.

Both Home Depot and Lowe's tell ABC News they do not share any information with third parties.
