TIPS FOR OPTIMAL PERFORMANCE
IDEAL SCREENING AREA
1. Locate a screening area in a stable 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. 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.
2. Set up your camera to be positioned perpendicular, both horizontally and vertically, to the
reference Heat Source and the face of the subject.
3. Measure and 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.
4. Verify that the field of view of the camera captures both the Heat Source and face of the
individuals being screened. The subject’s face should be directly next to the Heat Source.
5. Ensure that the reference Heat Source is not obstructed or accidentally moved from the field
of view of the camera during screening events. The Seek Scan software will not perform a
measurement event without the Heat Source detected in the scene. The Heat Source emits a
constant and known temperature. This allows Seek Scan to reference and calibrate the camera
prior to each assessment delivering high accuracy.
6. We recommend marking the ground with tape or floor decals to ensure all subjects are measured
from the exact same spot and while positioning the subject next to the Heat Source.
SCREENING RECOMMENDATIONS
1. Subjects should look directly at the camera during measurement.
2. For more consistent readings, ensure the subject’s eyes are clearly exposed by removing any
eyewear. Subjects wearing a facemask should pull it down slightly and subjects wearing a hat
should lift the brim to fully expose the eyes.
