U of H Information and Logistics Technology professor Chris Bronk says it's practically impossible to walk the streets of Washington, D.C. and enter a government building without being captured on a security camera.
"There's a strong technical capacity to not only capture images of people, but also to identify them," Bronk said.
Over the years, cameras have become a lot smarter. Security camera expert Luc Swimberghe says the ones used in high-level security systems are able to identify and categorize individuals based on clothing, accessories, or weapons in hand, but that's not all.
"Length of a beard, a tattoo -- something that would be unique to that individual," Swimberghe added.
Once those identifying images are captured on camera, they're fed through a database.
"And through there, they may have a farm of servers that are cross-referencing those images," Swimberghe said.
Facial recognition aside, there's another article of evidence that law enforcement will be looking into.
"Anyone who carried a cellphone into the Capitol yesterday essentially carried with them the means for their own conviction. The geo locations on the phone obviously are one piece of the puzzle," Bronk said.
