At SenSource, we pride ourselves on providing solutions using the latest people counting technology and vehicle counting technology. Our staff of engineers, software developers and technical support specialists ensure our sensing technologies and software meet the customer’s expectations, fit each unique application and are supported after installation.
PEOPLE COUNTING TECHNOLOGY
SenSource people counting sensors utilize the latest sensing technologies to meet the unique needs of customers. Our 3D stereo video people counter boasts 97% or greater accuracy guaranteed and uses the latest traffic monitoring technology, including queue management and dwell time capabilities. SenSource also offers a variety of mounting options and outdoor rated people counters, contact our sales team to learn more.
SenSource offers two series of vehicle counting technologies – Inductive Burial Loop and Pressure Hose systems. The Inductive Burial Loop is an accurate and permanent application requiring a wire loop to be buried underground. The Pressure Hose vehicle counter is a portable application counting each axel of vehicles passing over the pressure hose.
What sets SenSource apart from the competition is our Vea Reporting Platform. We offer customers secure data hosting on SenSource servers. Vea is a cloud-based reporting platform that is customizable and expandable making it the perfect fit for customers who simply want to view traffic data or customers who want a complete predictive analytics solution integrated with additional data sources.
Retailers, libraries, casinos, government facilities, universities and fast casual dining establishments are just a few industries using SenSource solutions. Learn more about how Vea Analytics software can be used in your industry.
A Timeline of People Counting Technologies
For the past two decades, footfall data has been collected using automated people counting sensors. As with all worthwhile technologies, continuous advancements are being made to improve the functionality, installation and user experience.
At SenSource, we take pride in the history of people counting technologies offered as each step forward is knowledge gained to better understand and assist our customers. Below is an overview of our current and past people counting technologies.
Stereo Vision 3D People Counting Technology
3D People Counters use dual video lenses to detect people and are the most accurate and reliable people counters. Stereo vision technology provides depth perception similar to the human eye so the sensors can measure distance. Since the sensors measure distance for all objects in their line of site, they can more easily distinguish between humans that should be counted versus other objects or shadows that should not be counted. 3D people counters have the ability to track and count all potential targets in multiple directions and zones because it has a bird’s eye view of the entry area. 3D people counters are much less susceptible to light variations, but must have a minimum amount of light (usually 2-3 lux) to operate accurately. Stereo vision 3D people counters count at 95% or better on average and it’s not uncommon to count as high as 98-100%. However, even with the highest quality video cameras and advanced detection algorithms, no sensor can be expected to count 100% accurate at all times.

Thermal Imaging People Counting Technology
Most thermal imaging people counters use a single thermal lens mounted overhead to detect infrared heat produced by humans. It’s a more accurate technology than photoelectric break-beam sensors and most monocular video sensors. Thermal imaging sensors have the ability to track and count all their potential targets in multiple directions and zones since it has a bird’s eye view of the entry area. They also have the advantage of operating independent of visible light sources, so they are ideal for unique applications with little or no light. Unlike stereo vision 3D people counters, thermal imaging people counters do not have depth perception and can only detect changes in heat. Therefore, inaccuracies result when the heat image of a human blends into the background (floor) or when the sensor mistakes other objects as humans. These sensors tend to lose their targets if people are standing still for several seconds resulting in missed or double counts. Thermal imaging people counters can generally be expected to perform at 90-95% accuracy.
Monocular Vision People Counting Technology
Monocular vision people counters use a single video lens mounted overhead to detect and count people. They are generally more accurate and reliable than photoelectric break-beam people counters. Monocular vision people counters have the ability to track and count all their potential targets in multiple directions and zones since they are mounted overhead. However, they only have the capability to detect shape changes in contrast to the floor using a 2-dimensional perspective. Unlike stereo vision 3D people counters, monocular sensors do not have depth perception and inaccuracies occur when shadows and shapes of other objects resemble the shape of a human. The sensor also requires good lighting conditions and has a tendency to lose targets if people stand still for several seconds resulting in missed or double counts. Monocular video people counters can generally be expected to perform at 85-95% accuracy.
Photoelectric Break-Beam People Counting Technology
Photoelectric break-beam people counters detect when a beam of light, usually infrared, is blocked. Each time the beam is blocked and unblocked, an internal counter is incremented. This technology is very simplistic in nature and therefore cannot distinguish what is breaking the beam, the direction of travel or if more than one object is crossing the beam simultaneously. If a person or object blocks the beam, no others passing through will be counted. Break-beam people counters should only be used to detect general traffic patterns in entrances where people will enter single file while also keeping a two-feet distance between them. Break-beam people counters are typically battery-powered and require frequent battery replacements. Photoelectric break-beam people counters should only be used to determine general traffic totals and fluctuations and shouldn’t be relied upon for high accuracy.
