4) Manual Calibration
Purpose:
The performance of this body thermography scheme offered by HIKVISION would be
affected by different actual working environments, and the affect factors in most
stable environments could be regarded as a kind of system error. If needed, it is
suggested to make a compensation through the manual calibration, the steps are as
following.
Steps:
1. Device start-up; wait a period of time (more than 60 minutes) for preheating.
2. For 5 to 10 individuals, complete the following 3 steps one by one:
 Use the ear thermometer or other specialized thermometer to get the real
body temperature, and record.
 Use the thermographic camera to get the body temperature of the same
individual, and record.
 Subtract these two numbers, and record the difference value.
3. Set Manual Calibration with the average value of these difference values in Body
Temperature Compensation.
For example:
If data recorded during the calibration process are as the following table,
Real Body
Temperature/℃
Measured
Temperature/℃
Difference
Value/℃
Average Value
(Manual Calibration)/℃
36.8
36.3
0.5
0.5
37.0
36.5
0.5
36.8
36.2
0.6
36.9
36.4
0.5
37.2
36.8
0.4
thereby setting the Manual Calibration as 0.5 degrees Celsius.
4. Other Notes for Use
 Before the device is used in actual body temperature measurement, it should run
for more than 60 minutes for preheating.
 This product is used for preliminary screening of people with Temperature. After
alarm happens, specialized medical thermometer should be used in further body
