Digital Inspection Systems is launching a vision-based safety system for hazardous areas, known as SHASS (Scorpion Hazardous Area Safety Solution). Trials have shown that the system can detect personnel in a hazardous area within milliseconds in varied light conditions and with a minimal false detection rate (in fact, during trials, false detections did not occur at any time and positive detections were experienced with 100percent success). The system does not use motion detection, so it completely ignores normal operational activity. "
