WHY RADAR OCCUPANCY COUNTING?

Reliable, Real-Time Occupancy Data from Anywhere.

Unaffected by lights, environmental factors or ceiling mount limitations, Xandar Kardian occupancy counting radars provide the most reliable sensing with extreme versatility.

BENEFITS OF UWB RADAR COUNTING

How it works.

Calibration Factor

Xandar Kardian sensors learn the room and create a virtual map which takes into account environmental factors such as air vents, machines, and furniture.  
 

Learn more
One-time, pre-set data allows the sensor to understand the environment (including vibrations from air vents and other machine created motion) as well as the average “routine” motion the occupants create in the given space via manual or automatic (In/Out) calibration. Approximately 2 million signal data sets create a virtual map for the radar sensor.
+
Real-time Signal Analysis

Once calibrated, the sensor will ignore the surrounding environment and focus on providing real time occupancy counts by measuring macro and micro vibrations from occupants.

Learn more
Once the space is calibrated, the radar continuously sends out 15 million impulse signals (40X safer than Wi-Fi) and collects information. For occupancy counting, it retrieves two primary data sets: radar signal reflection from the body mass (non-motion) and radar signal change from macro or micro-vibration (breathing patterns, hand/body motion). The two data sets are analyzed against the pre-calibrated signal definitions which provides real-time occupancy count estimations.

Occupancy Data

Xandar Kardian sensors provide real time counts for people in a space, traffic flow through doors, or simply whether or not someone is in the room.  
 

Learn more
One of the primary benefits of Xandar Kardian’s occupancy counting sensors is that it starts with 99% presence/vacancy detection as the base. While others just provide numbers, Xandar Kardian provides true presence/vacancy information first before counting. This enables building automation with 99% confidence in not creating discomfort to occupants on top of obtaining space utilization metrics. Never turn off lights orand HVAC when someone is still in the space!

Xandar Kardian In/Out Counting Sensor.


The CT500-IO enables foot traffic counting over any doorway or space regardless of door type, location, or height. This allows buildings to capture tower and building occupancy information in real-time and not just “spots” of foot traffic in certain hallways.

Xandar Kardian’s Occupancy Counting can provide you with this 


Optimizing building services such as cleaning, security, and HVAC systems can only be accomplished through complete building wide occupancy data. Other solutions on the market are either reliant on occupant’s devices or only provide localized information, while Xandar Kardian sensors can be installed where others can’t, leading to a comprehensive building occupancy count.

“It’s all about RELIABLE, CONSISTENT ACCURACY empowering building automation and space utilization analysis providing ACTIONABLE DATA.

FMCW (frequency modulated continuous wave) radars were originally developed to measure distance in real-time. Majority of the radars are in use today in vehicles for adaptive cruise control, blind spot monitoring and other ADAS applications. When used as a presence or occupancy counting solution, it works by plotting a “dot” in mid-air based on distance changes (body motion).
Ceiling only installation

It works great if the occupant creates a lot of motion which helps to plot many dots in the space. Unfortunately, if the occupant becomes too still....

It works great if the occupant creates a lot of motion which helps to plot many dots in the space. Unfortunately, if the occupant becomes too still, the dots disappear. Due to the nature of this method, “angular resolution” is severely affected whereby a person standing closer to the radar will block signals from someone farther away. This is the reason why FMCW radars are installed in the ceiling to avoid angular resolution issues.
Line of sight issue

FMCW radar solutions also suffer from “line of sight” issues as the signal is not able to penetrate through certain objects well. These include furniture and....

Xandar Kardian utilizes impulse radar ultra-wide band (IR-UWB) radar technology. It works by analyzing 15 million impulse radar signals per second which provides 99.9% presence/vacancy in real-time while also further processing the data to provide vital sign or occupancy counting data. This method provides ultimate reliability in the accuracy of the data without any conditions (such as constant body motion, line of sight) being applied.

The most widely used camera based people counting solutions utilizes 3D stereocope technology (two lenses) to determine “human shape” to count occupancy. The reason why 3D stereocope is used is because 2D images are notoriously difficult to determine if it’s an image of a person or an actual person. In fact, if a person is just standing or sitting down still for 1 minute, the system assumes that person as being part of the background (shadow). In recent years, newer systems paired with thermal sensors and lasers were introduced which also included RGB sensors to create a complex hybrid technology. Images were compared to secondary spatial data from heat or light signatures.

Regardless of what kind of technology is used, all camera lens based solutions must be installed from ceiling – looking down at the floor. This is due to angular resolution and line of sight issue. Therefore, total coverage area largely depends on how high the camera is installed – which is maximum 3.5M from the ground.

15 million radar signals are pulsed every second. Xandar Kardian’s proprietary radar signal processing algorithms analyzes it and determines the number of body-signal reflections and body motion measurements are in the area (milliseconds). This data is compared to the pre-set calibrated data to estimate occupancy count. It is 100% anonymous and is completely unaffected by lighting conditions, environmental factors. Angular resolution and line of sight issues are minimal if not irrelevant so long as it is positioned slightly higher than the average height of the occupants.

Xandar Kardian’s occupancy sensors does not provide you with the highest spot accuracy like camera systems can. However, it does provide you with true presence/vacancy sensing while also providing occupancy data where it was not possible before. Furthermore, it’s focus is more on consistency and reliability over spot accuracy. This means that the accuracy of the count data is more consistent than camera systems over time.
