Battery Operated StandAlone Non-Directional Side Firing Door Frame Counter
The operation of the TotalCounter SF people-counter is very simple. An Infrared Beam is sent from the transmitter to the receiver. When someone walks through the beam, the beam is interrupted, and a count is registered. The maximum distance between the infrared beam transmitter and receiver is twenty (20) feet. The TotalCounterSF enclosure is designed to fit on the 2″ frame that is around most doors.
The TotalCounter SF does not separate the counts as people enter and leave so you will need to divide the displayed count by 2.
Some of the Main Features of the TotalCounter SF include:
The TotalCounter SF is a small-size 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 “non-directional” people counters because they don not separate the IN and OUT counts. You will need to divide the total count by two.
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%
