•Operating Environment
A stable indoor environment without wind or direct sunlight
Working temperature: 50°−95° F (10°−35° C)
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 ft7 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.

4. Other Notes
Figure 7, Alarm Temperature
042120NA
•Before this handheld device is used for actual body temperature measurement, run for
five minutes for preheating.
•The measured human body temperature is the same as the measured Max Temp. Value
in this scheme; make sure that the Max Temp. Point is on the human face in the camera
view during measurement.
•This product is used for preliminary screening of people with elevated skin temperature.
If an alarm occurs, use a specialized medical thermometer as a further check.
•All of the above Installation and Configuration descriptions are based on the device
being used with fixed placement. Other uses as a portable handheld device or for
outdoor measurements are not recommended normally. Under these circumstances,
the temperature measurement accuracy may not meet the same standard.
