TASER / Axon Flex 2 Camera line art.
TASER makes the famous stun gun. Their Flex 2 camera is used by law enforcement officers as a POV camera that is attached to eyeglasses. It is connected to a controller that is magnetically held in place on the officer's shirt. Interestingly, the camera has a 2-minute buffer running so activity is recorded before hazardous activity takes place.
