2. Installation

• Installation Cautions

The performance of this temperature-screening scheme is greatly affected by the
environment. This scheme would apply only to indoor environments or scenarios with
calm air and consistent temperature. Besides, the relative installation location of
devices also greatly affects the temperature measurement accuracy. In order to improve
measurement accuracy, the installation environment has to meet certain requirements:

- Select installation environments with one-direction path to ensure that cameras

capture the full faces of all passing persons. It is recommended that people stop
movement during measurements.

- Select indoor environments with calm air and consistent temperature condition.

Outdoor environments with rapid temperature changes are not recommended.

- If this scheme is used in entrance scenes that connect indoor and outdoor

environments, it is suggested that the installation location be kept at a certain
distance from the entrance (such as customs or security checkpoints). Persons
coming in from outdoors should stay indoors for more than five minutes before the
measurement. In these ways, the influence of the outdoor temperature on
measured body surface temperature could be reduced.

- Avoid objects with high temperature placed in the scene.

• Camera Installation

- The camera should be set in front of the one-direction path, capturing the full faces

of passing persons, as shown below.

Figure 1, Camera Placement and Positioning

- Recommended installation height is 4 ft 11 in−5 ft 7 in (1.5 m−1.7 m), namely the

camera should be set at the same height as human faces, or even be set at a
lower elevation angle, thereby reducing error caused by other heat sources near the
ground.

- The distance between the camera and measured object is recommend to be set to

3 ft 4 in−6 ft 7 in (1 m−2 m) normally.

- Avoid any other object whose temperature is higher than a human body in the

camera view background.

- This handheld thermographic camera can be mounted on a tripod without extra

adapters. There is a tripod offered by Hikvision for fixed placement, but it requires
additional purchase. As domestic suppliers have not fully restored production
capacity recently, there are multiple suppliers, and there may be slight differences
under the same model, which will not affect the use. If you are concerned about
this, we recommend that, except for tripod adapters that should be purchased
together with the products, tripods that meet the standards could be purchased
locally.
