What it does: Makes a digital camera system primarily used to monitor the behavior of commercial drivers. Why it's growing: The technology saves customers between 30% and 90% on loss and casualty costs, says CEO Bruce Moeller. How it works: A camera with a 270-degree view is mounted behind a vehicle's rearview mirror. When there's an irregular motion, like sudden braking, the camera records the incident.
