  1. Stand with thermal camera and visitor display.
  2. Screening position.
    It is important to clearly mark the screening position (where the person should stand for the screening). The distance from the camera lens to the center of the screening position shall be 160 cm (5.2 ft.).
  3. Queueing system, e.g. barriers and arrow floor stickers.
    The queueing system will guide the visitors into the screening station, to the correct screening position, and out of the screening station. A recommended standard is to keep the queue at least 90 cm (36 in.) wide. To make sure people do not cut the corner and end up too close to the camera, about 45 cm (18 in.) should be added to the barrier leading in to the screening station.
  4. Optional: Backdrop.
    A backdrop may be needed to prevent background disturbances from reaching the camera, such as passing or queueing people.
    Additional, not in the figure:
  • Bluetooth button (Remote operation button).
    Used in Button mode to trigger the screening.
  • Optional: Operator display.
    Secondary display placed near the operator for monitoring.
  • Optional: Information roll-up.
    Roll-up that informs people what the screening is about and why they need to do it.
  • Optional: Instruction roll-up.
    Roll-up that tells people to remove eyeglasses before they are screened.
