The TotalCounter USB is an infrared beam-break people counter. The infrared transmitter side (the side without the display) sends a safe and invisible infrared beam to the infrared receiver (the side with the display).  When someone, or something, passes through this invisible beam, they “break” the beam and are counted.  These people counters are known as “directional” people counters because they  separate the IN and OUT counts. 

The physics of a beam break people counter means that if two people walk through side-by-side, they will be counted as one.  And if a group of people walk through at the same time, it is unlikely that all of them will be counted.   ALL infrared beam-break and ALL infrared-reflected people counters work in the same way.  On a single door entrance (typically 36″ wide), most people enter one at a time, so the counting accuracy is typical very high (93 to 95%). But on a double-door entrance – this typical accuracy can drop to 80 to 85%.
