What is the difference between infrared people screening and traditional people screening?

People screening is mostly used for safety inspections in airports, customs, seaports, and subway stations where human body temperature must be checked. In general, there is still a big difference between infrared people screening and traditional people screening, not only in terms of price, but also in terms of use. People screening can accurately determine the area where the metal material object belongs. Also, people screening can visually display information based on the doorpost lights.

What is the difference between infrared people screening and traditional people screening?

Infrared people screening has four core advantages: safety, intuitiveness, efficiency, and prevention of missed inspections. Ordinary people screening only have a single-point measurement function. Infrared people screening can capture the overall temperature distribution of the measured target, quickly finding high and low temperature points so as to avoid missed detection.

Although the ordinary people screening has a laser pointer, it only serves as a reminder of the measured target. The laser point of traditional people screening is not equal to the measured temperature point, but the average temperature in the corresponding target area. However, infrared people screening does not have this problem because it displays the overall temperature distribution with a clear glance. Most infrared people screening on the market have laser pointers and LED lights, which are convenient for rapid location and identification on the spot. For certain detection environments with safety distance restrictions, traditional people screening cannot meet the needs. Because as the measurement distance increases, the target area for accurate detection is enlarged, affecting the derived temperature value.

How to test the stability of people screening?

The stability of the people screening is very important, which is a condition for customers to choose and purchase. Unstable people screening can cause chaotic alarms and leak alarms, which cannot play a real role. Since the sensors of the people screening are open to the outside world, it can emit electromagnetic waves to the external environment and can also emit electromagnetic waves generated by the external environment. The external environment produces electromagnetic wave equipment, which will interfere with the normal detection of people screening. Although all people screenings are more or less subject to external disturbances. technical force can handle external interference to reduce interference.

Generally, the people screening should be designed as a real-time signal strength indicator, which can display metal size and interference signal strength. During the first installation process, we should adjust the people screening according to the instructions to minimize the interference of the external environment.

Choose to conduct experiments in the same environment. After the power is turned on, the infrared radiation device of people screening is shielded to remove the infrared limit alarm function. If there is a lot of brightness, or even generate an alarm, you can try to change the working frequency to avoid interference outside.

How to set the sensitivity of people screening?

When setting the sensitivity of each zone of people screening, the larger the value, the higher the sensitivity. While the smaller the value, the lower the sensitivity.

First press the power button to reset the screen, and then press the "Select" button of people screening. The display panel will display "CCCC". Press "Select" again and it will display "1234". If the display is not "1234", press the "Power" button of people screening again to reset. Repeat the above operation until "1234" is displayed. Then press the "Confirm" button of people screening to display "0000" with a beep, and then press the "Confirm" button to display "FFFF".

When the display panel of people screening displays "FFFF", press the "Select" key. The upper displayed on the display panel is "L001", which represents the first metal detection zone. The lower line is "095", which represents the sensitivity of zone 1. When you need to adjust sensitivity of people screening, first press the "Enter" button of people screening to adjust the single digit, then press the "Adjust" button to adjust the tens digit. After adjusting the sensitivity of Zone 1 according to the actual situation, press the "Select" key of people screening to switch the zone.
