1. Overview
DTC300 is a dual-spectrum accurate temperature measurement camera, which is developed for the
body temperature screening and has the characteristics of non-touch, high sensitivity and flexible
installation etc. It can be used for quick temperature detection, and trigger the alarm system when the
pedestrian who has abnormal body temperature passes through the orderly channel in public place
(such as hospital, enterprise, school, community, mall and supermarkt etc.), with its integrated high
precise infrared temperature measurement camera and accurate face recognization technology. It
roles as a quick tool and provides accurate body temperature data during the period of fighting with
epidemic.

3.2 Mounting and Connecting Thermal Camera
As shown in figure 2, there is a 1/4-20UNC hole at the bottom of camera, which is used to mount
camera to a adapter bracket or quick shoe.
Figure 2 Bottom diagram of DTC camera
Take the thermal camera mounted on a tripod as an example. Please find the specific installing steps
as following.
Install the quick shoe at the bottom of camera with a 1/4 screw, and install the camera on the
PTZ of tripod, locking the screw at side. As shown in figure 3.
Figure 3 Installing diagram
Plug Type-C data cable to the left interface, and then plug the module cable to the right
connector. As shown in figure 4.

Plug the three USB interfaces at the other end to the computer which has installed DTS PC client.
As shown in figure 5.
Figure 5 Connecting diagram of PC
After powering on computer, the camera startup automatically with the sound of shutter working.
Please wait for 40 minutes before performing measuring to ensure the measurement accuracy.
3.3 Site Layout Solution
1）、Reference layout
Refer to Figure 6 for the layout plan in a wide space area. The external reference blackbody is
placed directly in front of the infrared camera and made it observable in the imaging field of
view. Pedestrians need to be guided and make sure all of them can be observed with the thermal
imaging camera.

Installation direction and height of camera
The installation distance and height of the camera should be arranged according to the actual
situation, the recommended distance is 2m, and the installation height should ensure that all of the
observed pedestrians can appear in the field of view.
Reference blackbody layout
As shown in Figure 7, adjust the direction and position of the infrared human body thermal
imaging camera and the reference black body so that the reference black body appears in the 2/3
central area of the camera market and shall not be shielded by pedestrians.
Figure 7 Infrared imaging on PC
Environmental requirements
The infrared temperature measuring camera is arranged in an environment where the
temperature is relatively constant and there is no direct sunlight, to avoid temperature measurement
errors caused by the temperature changing environment affecting the human skin surface temperature.
According to the above installation requirements, the following installation methods can be used to
install equipment in halls and aisles.
3.4 Site Installation and Layout Considerations
1）、Avoid placing it at the entrance with airflow disturbance
Avoid the temperature rise and fall caused by the air surface disturbance of the skin of the
person being tested, which will affect the false alarm or miss alarm of the infrared temperature
measuring camera.
