Learning Objectives

After reading this article, you’ll be able to:

  • Define XOVIS installation location, taking into account the detection area compared to ceiling height and the area you want to cover

Create sensor layout

As described in Prepare your sensor plan, you’ll need following elements in order to define where to place each sensor:

  • Avoid setting up count area at the edge of the detection area.

    • It's a best practice to include 1.5.m coverage on all sides

    • ceiling height

    • ceiling material + information on type of ceiling (e.g. suspended ceiling)

    • ceiling pictures / videos

    • dimension (horizontal) of the passage

    • cover more than one KPI with one sensor possible (optimization of the positioning of the sensor)

    Tip

    Best practices recap

    Detection area is measured on floor level: any person standing on the edge of the detection area might not get picked up.

  • Specific for XOVIS headcount sensors: 

    • Traffic line: 1 single sensor for 1 traffic line (this takes into account for CPU and calculations, otherwise accuracy will drop)

    • Define the Detection Area of each sensor

    A XOVIS device is always placed in the middle of its Detection Area, which is a rectangle of which the dimensions (length-width) on the ground are dependent on the installation height/ceiling height.

    Info

    For optimal performance, the XOVIS™ installation height above the floor should be between 2.2m (7ft) and 6m (20ft).

    The following table shows the Detection Area size for different sensor heights:

    Define sensor installation location

    The installation location of the XOVIS sensor devices is linked to the height of the ceiling installation (usually: ceiling) height and dependent of any obstructions of large items (for example an HVAC duct or light fixture).

    Determine the sensor's precise location according to the layout defined in the sensor layout process and the resulting floor plan (Sensor Plan). Sensors are displayed as circular icons on the floor plan, with an arrow pointing in their view direction.

    For optimal performance in tracking hallway traffic with your Xovis PC2SE sensor, it's best to install it with the longer side facing the walls:

    • Field of View: The PC2SE has a wider field of view (FoV) along its longer side (45° compared to 25° along the shorter side). By positioning it this way, you capture a larger area of the hallway, ensuring better detection of people entering or exiting through the door.

    • Target Size and Accuracy: In a long hallway, people walking towards the sensor present a smaller target profile compared to walking parallel to it. The wider FoV along the longer side helps compensate for this smaller target size, improving detection accuracy.
