The process of releasing suspects' photos to the public has gone from days to hours, as noted by the most recent bank robberies in Knoxville this week.
On Tuesday, two separate robberies occurred in city limits: one at the UT Federal Credit Union on the UT Campus, another at the Enrichment Federal Credit Union in North Knoxville. In both cases, the public saw photos of the suspect in just a few short hours. Other banking leaders said that was not the case just a few years ago.
"If you need a picture off of (the footage), it took somebody from the security company to come and take the film out, send it off, and it would be several days before you got the picture back," said Daryle Keck, president and CEO of Jefferson City-based First Peoples Bank.
"Technology has changed a lot," he added.
Cameras in the last decade went from VCR-based tape that would take a few frames a second, to digital 20 frame per second footage.
"We moved away from the tape where it laid the image down on a digital frame, a hard drive and made it a lot easier to manage the data," said Mike Fleenor with Fleenor Security Systems in West Knoxville.
That digital footage also has higher resolution, detailing more attributes about a suspect than tape, which can blur important traits in catching a criminal.
"True digital signal from the camera and the I.P. network camera down all the way through to the recorder, which is a digital hard drive recorder, and that's made a world of difference as far as the quality to retrieve the images," Fleenor added.
Bankers are always reminded to be on top of surveillance technology trends.
"It's constantly changing and I can't imagine the next changes in technology, but it will," Keck said.
