The operation of the TotalCounter I/O 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 interupted, and a count is registered. The maximum distance between the infrared beam transmitter and receiver is thirty (30) feet.
The TotaI Counter I/O is a battery-operated, infrared beam-break people counter that is used in a standalone mode where you walk to the counter to read the total IN and total OUT counts AND THE OCCUPANCY DIFFERENCE from the display and reset to zero using a magnet. The TotalCounter I/O separates the counts as people enter and leave.
Some of the Main Features of the TotalCounter I/O include:
- Provides IN and OUT count data.
- PROVIDES AN OCCUPANCY COUNT
- Large six-digit liquid crystal display, 0.25 inch character height.
- Measures across a 30 foot span
- Magnetic reset switch.
- No reflector – no misalignment issues – easy to install.
- Easy alignment tool is included.
- Battery Type: Standard 1.5 Volt, AA Alkaline. 2 per side. User replaceable.
- Rugged enclosure design
- Silent Operation
- Mounting bracket included for ease of installation..
- Sensor Dimensions: 4.5 inches x 2.75 inches x .1 inch deep
- Typical Operating Environment: 0 to 120 degrees F. Protected from weather.

The TotalCounter I/O 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%.
