Understand XOVIS's people counting
Define if XOVIS’s data types suit your use case
What is Xovis?
The XOVIS sensors detect people flow across a(n imaginary) traffic line, and send analytics data over a secure, encrypted network connection.
Traffic Line areas are intended to track traffic going in and coming out of a specific location. They produce information such as “In the last update period, 5 people crossed the Traffic Line going IN to the area, 3 people crossed the line going OUT”. The delta, or difference, between these two values provides us with the information on how many people are still in the tracked area (utilization).
How does it work?
Non-intrusive solution – images are never transmitted or stored on the sensor
All of the image processing is done on the sensor itself, the sensor does not store or output images, and has no interface to extract images, so privacy is fully protected.
Data is only transmitted in text format and without any kind of personally identifiable information.
How often is data captured?
Technically, the sensor is always on and will could update the Workplace platform as soon as a detection as has occurred.
As a default, the data is uploaded into the Workplace Cloud every 1 min: this interval is low enough, that a person will be captured, yet it also reduces false detection issues.
How is data treated?
In theory, the traffic line counter would just continue counting. Because of the use cases within the Workplace platform (know daily flux of people coming in and going out; and indirect utilization), counters are reset at midnight.
XOVIS Accuracy
XOVIS provides highly accurate data on Traffic Line detection, yet some factors might impact people detection:
Make sure lights are turned on/there is enough daylight. It should not be too dark in the room
Nothing should be blocking the sensor detection area
items might be suspended from the ceiling (eg HVAC or light fixtures)
items might be too high and block visibility (eg high back chairs or office screens)
Reflections in windows (might be avoided by restricting count area in the configuration)
Installation needs to be level (not tilted)
Installation location: make sure to verify measurements (height + length/width) in the config platform
