TIPS FOR OPTIMAL PERFORMANCE
IDEAL SCREENING AREA
1. Locate a screening area in a stable, well-lit indoor controlled environment with a temperature
range 68-76°F (20-24°C) and relative humidity range from 10% to 50%.
2. Locate a screening area to avoid significant convective airflow from blowing onto or into the
screening area (e.g. from air conditioning ducts, or open doors or windows).
3. Locate a screening area to avoid thermal sources either hot or cold (i.e. sun-facing or cold
windows, radiant heaters, outside walls, strong lighting), particularly within the field of view of the
Seek Scan camera.
4. Backdrops and side screens can help ensure a controlled screening area. If used, they should be
thermally uniform, non-reflective, and not dark in color in the visible spectrum (closer to white
than black). Reflective panels such as glass panels should be avoided or covered with opaque
materials.
IDEAL SEEK SCAN SETUP
1. REMOVE GLASSES. Seek Scan targets the eyes first to make the most accurate measurement.
2. Set up your screening area with the camera pointed at the Heat Source in front of a wall. This will
help create a flat thermal background and allow for faster scan times and more reliable readings.
Warm objects in the background that are near a person’s skin temperature or warmer than 104°F
(40°C) may reduce system performance and stability.
3. Make sure that the subjects being scanned and the Fixed Heat Source are in the same position
in the scene during every scan. We recommend marking the ground with tape or floor decals to
ensure all subjects are measured from the exact same spot.
4. Confirm the distance from the Heat Source to the Camera is no further than 5 feet (1.5 meters).
Seek Scan has been qualified to work at 5 feet (1.5 meters) to accommodate people of different
heights. Seek Scan can work as close as 4 feet (1.2 meters) as well. In such a setup, Seek Scan
algorithms will work more efficiently but not cover has many different height variations.
5. It is very important to place the fixed heat source and the subject at the same relative distance
from the camera. Placing the heat source slightly behind or in front of the subject is acceptable,
try not to create more than 8 inches (0.2 meters) of separation. The heat source must remain
complete exposed and visible by the camera during every measurement.
6. It is important to remember that Seek Scan will focus primarily on the eyes to make a
measurement; therefore, only a person’s eyes and up need to be present in the scene.
SCREENING RECOMMENDATIONS
1. Subjects should look directly at the camera and remain still during measurement.
2. For more consistent readings, ensure the subject’s eyes are clearly exposed by removing any eye
wear. Subjects wearing a face mask should pull it down slightly, and subjects wearing a hat should
lift the brim to fully expose the eyes.
