Screening station — General description

3.3.1 Mounting and placement considerations

For accurate screening results, the following factors related to mounting, placement, and

distances must be considered:

• The camera shall be placed under the display.

• The screening position shall be perpendicular to the camera. The distance between

the camera and the screening position shall be 1–2 m (3–6 ft.). The screening position

shall be clearly defined, e.g. by marks on the floor.

• The camera shall be angled upwards, so that it aims at the head of a person standing

at the screening position.

• A backdrop shall be placed behind the screening position, providing a uniform and

non-reflective background.

For accurate screening results, the following factors related to the environment around

the screening station must be considered:

• The screening area should have a non-reflective background and minimal reflected in-

frared radiation from the surroundings. This can be achieved by placing a backdrop

behind the screened person.

• Make sure there are no glass windows or doors in front of the camera. The windows

can cause reflections and incorrect temperature measurements.

• Make sure there are no heat sources near the screened person, including hot lamps,

sun light, electrical equipment, etc. This can increase the skin temperature.

• Make sure no beams from intensive energy sources go into the thermal camera. This

includes devices that emit laser radiation, or the sun. The beams can have an un-

wanted effect on the accuracy of the camera. They can also cause damage to the

camera.

• The measurements can be influenced if the screened person is sweating. For that

reason, the relative humidity in the screening area should be maintained below 50 %

and the temperature below 24°C (75°F).

• Prevent drafts from sources such as air conditioning from blowing directly onto the

screened person. The air flow can cause cooling or heating of the face.
