Polygraph accuracy

By combining two world leading technologies (computerised polygraph and EyeDetect) we provide much higher accuracy rates than polygraph alone. EyeDetect records changes in pupil diameter, eye movement, reading behaviour, blink rate and eye fixations at a staggering 350,000 metrics during one examination, something that polygraph could only hope to achieve.
