1. Alarm switch： If you choose to allow the alarm, the system will issue a warning to remind the staff according to
the set mode. If not checked, the alarm event occurs without any alarm processing. It is suggested that this item be
checked！
2. 2. Setting of high temperature alarm interval： When the measured target temperature is within the set
temperature range (such as the following 37.3℃ ~ 42.0℃), the alarm event is judged to have occurred. The
maximum temperature range of high temperature alarm is 30.0℃ ~ 50.0℃, as shown in FIG. 4-6.

3. Alarm sensitivity : Including three modes: advanced, standard, and custom. In the first two modes, the
minimum alarm targets are 4 and 8 pixels, respectively, and cannot be changed；When selecting the custom
mode, the size of the minimum alarm target can be selected by dragging the left mouse button and the scroll wheel.
4. Number of alarm targets ：Setting the number of alarm individuals displayed on the image, and the
maximum number is 8.
5. Alarm delay time： In order to avoid the alarm caused by accidental temperature difference, the delay time
is set to collect the temperature change within a period of time, so as to reduce the alarm error.
6. Transparency of temperature scale ： Set the transparency of the temperature mark, ranging from 0 to 9,
0 is full transparency.
7. Face recognition switch： The switch is on by default. When the preset hot object is detected, if the switch is turned
on, the system will first determine whether the hot object is a face. If it is judged to be a face, it will grab the picture
to alarm, otherwise it will not grab the picture to alarm.
8. High temperature tracking：This switch is turned on by default. When a hot object is found in the detection area,
the system will automatically track the hot object and the cursor will always follow.
4.2.2 Settings of shielding area
There are always some hot heat sources in the monitoring area，such as the light box,billboard, fast-food
restaurants etc，the temperature of these heat sources is similar to human body, which can easily lead to false
alarms in the system.In order to remove these disturbances, these heat sources can be shielded and the area is not
alerted.
1. Click “Settings” in the main screen—>“system setting”—>“shielding area”，enter the screen of shielding area, see
FIG 4-7.

2.2.1 Black body area setting
The black body temperature measurement uses the actual temperature of the black body as the reference temperature.
In order to make the device accurate temperature measurement, the black body target area must be framed. The specific
equipment steps are as follows:
1. Click the "Settings" button in the main interface-> "System Settings"-> "Blackbody Area" to enter the blackbody
area setting interface, as shown in Figure 4-8
2. Select the "Black Frame" option, move the mouse cursor to the infrared image, find the black body
heating target surface in the infrared image, hold down the left mouse button and drag the frame to select the
center heating area of the black body target surface, and then click the lower left corner of the window Save
button。
3. Select the "Black frame" option again, move the mouse cursor to the infrared image, find the black body heating
target surface in the infrared image, hold down the left mouse button to draw a rectangular frame to just frame the
black body target surface, and then click the bottom left of the window Corner "Save" button.
Fig.4-8 blackbody area setting
When the system is working, the user can choose whether to display the black body or not. If the "allow to display the
black body" is checked, the black body heating target surface can be seen in the infrared image.
As an important reference heat source for temperature measurement, the black body is not allowed to be blocked or
moved. In order to prevent the black body from being blocked or moved, it is necessary to turn on the black body
shielding function. Check the button of "show black block prompt" and then click "save" to complete the setting. When
the black body is bumped or blocked, a prompt box will pop up automatically on the main interface of the software to
remind the staff to deal with it, as shown in figure 4-9.

Fig.4-9 Black block shift prompt
Ambient temperature setting (ambient temperature setting in the temperature measurement area) has a great
influence on the accuracy of temperature measurement, so please input the ambient temperature accurately
according to the actual situation.
2.2.1 Image registration
The system adopts the dual cursor synchronous display method of infrared video and visible video, but since the
infrared temperature camera and visible video camera have different field angles, it is impossible to make the two
cameras completely parallel in the installation, resulting in the position of the same target in the two videos looks
inconsistent. In order to accurately find the corresponding relationship between the infrared image and the visible
image, a video registration algorithm is added to the software. The mapping relationship between infrared region and
visible region can be obtained by registering the three pairs of alignment points in visible region and infrared
region. By this mapping relationship, the accurate coordinates of high temperature target coordinates in infrared image in
visible video can be calculated.
