Drivers in some cities will have more than traffic and dashboard cameras watching their every move.
Cities are now taking surveillance even further and mounting cameras on police officers. Officials said the device -- called the "Axon" -- will make everyone safer.
However, technology like this isn't cheap. The cameras cost about $1,700 each.
To use the device, an officer puts on a headcam. A cable attaches the controls to a small monitor. The camera is always recording, but the officer has to press a button to keep the images.
"So if something happens... I come down here [and] hit this event button, and that captures the previous 30 second buffer," explained Tom Smith of Taser International -- the company that makes the Axon.
Once images are recorded they can never be deleted or changed, he added
"So it's capturing not only the ambient sound, but it's capturing the radio traffic," Smith said. "You're going to act differently if you know you're being recorded."
Because the recordings are original, they can also provide evidence to clear up "he said-she said" situations for officers and citizens.
One sheriff's department in Arizona is already using the Axon and it's being tested by several other law enforcement agencies.
