Dallas Love Field Airport is installing more than 500 HD cameras throughout the facility to monitor travelers as they check their bags on the curb and all the way to the gates, according to an article from NBC.

While senior manager of IT operations Karl Martin can’t say exactly what technology is going into the airport, he did say that the new equipment will be able to zoom into areas where the old cameras couldn’t monitor.

The new camera system costs between $6 million and $7 million, which is partly paid for by a $3.4 million grant from the TSA, the article says.

Martin also said that the HD system could allow TSA and airport officials to use facial-recognition software and even receive video and pictures on their cell phones during an emergency.
