Nowadays surveillance cameras are everywhere, and recording everything in better quality than ever before.
"Within probably (the last) three to five years, we've seen more advancements in technology in surveillance than we've had in the last 30 years," said Jeff Voyles, an International Gaming Consultant who deals with a lot of casino surveillance systems.
Voyles told FOX5 he was encouraged by the quality of video the FBI released of the Boston bombing suspects.
"The image of those particular two suspects is very clear. It's a very good image to pass around," Voyles said.
Voyles said sometimes older systems won't give you the same quality of picture.
But he said it appears the cameras that captured the images in Boston are newer, which means investigators can take a closer look for details which might identify the men.
"Digitally enhance it and then it looks like a puzzle, so they're able to look at each frame and each megapixel to see whether or not they can see something," Voyles said.
Las Vegas Metro Police Department said similar surveillance video, especially cameras inside of casinos, has helped them catch and convict countless criminals.
"Las Vegas is very fortunate that we have the hotel district that has all the sophisticated systems in place," said Officer Larry Hadfield with the LVMPD.
Meanwhile Voyles said facial recognition software likely won't identify the Boston bombers because they may not have criminal records.
Facial recognition, according to Voyles, only deals with known criminals.
But moving forward, Voyles said the images can be used to alert law enforcement if another surveillance camera sees them.
"Each area of that face has its own code, so you can made that person, which is how they identify that person using only their face," Voyles told FOX5.
