How To Configure the Camera and Black Body

How To Configure the Camera and Black Body

The black body must be configured to the camera after the camera has been added to the NVR. For more information on how to add the thermal camera into the thermal NVR, click here.

Note: Before configuring the camera and black body please ensure there is adequate lighting in the area. Any inadequate light source may cause inaccuracy with thermal readings. For more a detailed guide on how to configure your thermal monitoring system, click here.

Step 1: Access the web user interface (web UI) for your system. and access the camera registration screen. For more information on how to access the web UI for your system, click here. 

Step 2: In the Registration menu, click on the “e” symbol in the interface to load the camera’s web UI in a web browser.

 Log into the web UI for your camera using the camera’s login credentials. If this is your first time logging into the web UI, the default username and password will be admin.

Step 3: Set a Smart Plan: In the camera’s interface, navigate to Setting>>Smart Thermal>>Smart Plan and ensure the thermometer icon is enabled. The icon will be yellow once it is enabled. Click on Save.

Note: Ensure the black body is positioned on the right or left side of the image and is not being blocked. It is recommended to position the black body towards the top right of the screen as demonstrated in the image below.

Step 4: Set Black body Parameters: Click on the Black body Parameter tab then click the Enable checkbox. The black body temperature is 95°F(35°C) (the default value). Confirm that the maximum temperature, the minimum temperature and the average temperature are all within 35°F ± 0.2°C. Click on Draw Area and set a calibration area around the highlighted edge of the black body. The rule will be displayed as a green box.

Due to environmental differences, the temperatures read by the system may experience errors. For instance, if more than 5 people in the image are at optimal distance and the measured temperature is too high or too low, compensation can be established using temperature correction. 

For example, if the temperature is 0.5°C too low, fill in 0.5°C as a temperature correction. If the temperature being read is too high, fill in -0.5°C as a temperature correction. Click Save once all settings have been made.

Step 5: Set the Body Temperature Monitoring Rule: Click on Human Temperature Measurement and click on the Enable checkbox.

Note: A human must stand on the edge of the black body, roughly 10 ft from the camera, facing the camera while configuring this rule.

Click on Draw Area and use your mouse to draw a thermal detection area on the screen between the shoulders and above the forehead of the tester. The detection area should not contain the black body in the rule.

Enable the “Temperature report” and “High temperature abnormal alarm” options. Set the “High temperature abnormal alarm to 99.1°F(37.3°C). This will alert the system when a temperature reading is above the specified threshold.

Set the “Temperature Lower Limit” to 77°F(25°C). This will alert the system when a temperature reading is below the specified threshold.

Enable “Audio Linkage” and “White Light” and use your mouse to increase the size of the face identification frame in the Face Marking menu. Click Save

Step 6: Smart Channel Setting: Click on the Smart Channel tab in the Human Temperature Monitoring menu.

The visible light and thermal options in this field are optional. Visible light is used to detect faces by default. If the effect of visible light is not visible, such as backlight, or insufficient light, etc., thermal imaging detection can be used, such as the Snap Angle Filter. Please note, the higher the value of the snap angle filter the easier it is to capture a side of a face. For example, if the value in the slider is set to “1”, it will only detect the front of the face. Click Save.

Step 7: Compensation Settings: Click on the Compensation Settings tab located in the Human Temperature Monitoring menu. Use the dropdown menu in the Temperature compensation field to select between; a mercury meter compensation (default), or a forehead temperature meter compensation. These modes should be selected on a case by case basis, otherwise it should be left as default. Click Save.

Step 8: Ambient Temperature Setting: Click on the Others tab located in the Human Temperature Monitoring menu. Confirm whether the “adaptive ambient temperature” is consistent with the actual ambient temperature on site. If not, input the accurate ambient temperature on site in the Ambient Temp Settings field. The temperature should be entered based on the scale of measurement (°F or °C) indicated in the field. Click Save.

Step 9: Binocular Target Setting: This function allows you to provide fine adjustments to your thermal settings. Navigate to the live view screen of your camera and click on the adjustment icon located in the bottom left portion of the interface.  Use the up, down, left, and right arrows to adjust the detection area (face box) on the screen.

Note: If the visible light option is enabled in the Smart Channel tab, the visible light in the detection box will be prevalent. The frame should only be adjusted on a case by case basis and must be accurate based on the thermal imaging face frame.

Step 10: Test: Once all settings are confirmed it is highly recommended to test for accuracy. Return to the live view screen and make sure accurate temperatures are being recorded under normal conditions. To test high temperature alarms, place an object with a higher temperature to the forehead and remove. The temperature alarm will sound once the temperature threshold is met.
