1 Product Overview
1.1 Thermal Imaging Principles and Advantages
For any object, as long as its temperature is above the absolute zero (-273.15°C), although the object does not give out light, it can radiate infrared. The infrared is also known as thermal radiation. A temperature change occurs when the infrared radiated by objects at different temperatures is absorbed by the infrared thermal detector, and thereby generating an electrical effect. An electrical signal is amplified and processed to obtain a thermal image corresponding to the distribution of heat on the surface of the object, that is, infrared thermal imaging.
Applicable to any light environment Traditional cameras rely on the natural or ambient light for imaging. However, the
infrared thermal imaging camera can clearly image the object with the infrared heat radiation of the object without relying on any light. The infrared thermal camera is applicable to any light environment and is free from glare impact. It can clearly detect and find the target as well as identify the camouflaged and hidden target in both day and night. Therefore, it achieves real 24-hour surveillance.
Monitoring the temperature field of the target heat distribution The infrared thermal camera can display the temperature field of the object and
change the surface temperature distribution of the object that cannot be directly seen by human eyes to the thermal image representing the surface temperature distribution of the object. By monitoring the temperature field, you can immediately identify the temperature abnormality, thereby preventing potential risks caused by the temperature, such as fire.
Providing the cloud penetration capability Atmosphere, dust, and clouds can absorb visible light and near infrared, but are
clear to the thermal infrared for 3 to 5 microns (medium wave infrared region) and 8 to 14 micron (long wave infrared). Therefore, it is difficult for the conventional cameras to capture clear images under dense clouds, while the thermal imaging camera is able to effectively penetrate the atmosphere and clouds to capture clear images.

In the black/white display mode, this range is converted to the grayscale tones. For example, 0 indicates completely black, and 255 indicates completely white. The temperature field of the scene is converted to images by using the grayscale ranging from 0 to
255. Different polarity modes can be converted to different display images. The most common setting is white hot (a hotter object is displayed brighter than a colder object) or black hot (a hotter object is displayed darker than a colder object). The difference between two modes lies in that the temperatures corresponding to the darker one and the lighter one are reversed. Other modes include rainbow, ironbow, HSV, autumn, bone and so on.

The sharpness of normal thermo graphic images is lower than the visible light and it is difficult to use the normal thermo graphic images to identify the original images of the targets. The image enhancement and edge processing technology can be used to get better recognition and distinguishing effects. The dynamic DVE is classified into six levels, ranging from 0 to 6. You can set the DVE according to an actual requirement.

FFC Mode
The internal of the thermal imaging camera may comprise the mechanical action correction mechanism that can periodically improve the image quality. This component is called flat field correction (FFC). When controlling the FFC, the FFC shields the sensor array, so that each portion of the sensor can collect uniform temperature fields (flat field). By means of FFC, the camera can update the correction coefficients to output more uniform images. Throughout the FFC process, the video image is frozen for two seconds and a static-frame image is displayed. After the FFC is complete, the image is automatically recovered. Repeated FFC operations can prevent the grainy and image degradation problems. The FFC is especially important when the temperature of the camera changes. For example, after the camera is powered on or the ambient temperature is changed, you should immediately perform the FFC.
Auto: In the Automatic FFC mode, the camera performs FFC whenever its temperature changes by a specified amount or at the end of a specified period of time (whichever comes first). When this mode is selected, the FFC interval (minutes)

ranges from 5 to 30 minutes. The temperature change of the camera is based on the temperatures collected by the internal temperature probe. The temperature of the camera sharply changes when the camera is powered on. The FFC is relatively frequent, which is normal.
Manual: In the manual FFC mode, the camera does not automatically perform the FFC based on the temperature change or the specified period. You can press the Do FFC button to select the manual FFC mode. When you feel that the image is obviously degraded but the automatic FFC is not performed, you can use the manual FFC function to check whether the image quality can be improved.
External: In the external FFC mode, the internal mechanical action correction mechanism is disabled. The uniform source (black body) is placed in front of the camera. This feature is useful if there are lens or lens mount non uniformities that are not corrected by an internal FFC. The camera will not perform an FFC process on startup if the saved state of the camera is External mode FFC. Many customers have found that the palm of their hand or a table is an adequate uniform source to perform an External FCC.

In the automatic FFC mode, the FFC interval ranges from 5 to 30 minutes.

Compared with images generated based on visible light, IR images boast the features of high background and low contrast. In an IR image, background radiation occupies a big part of dynamic display scope and the target object occupies less dynamic display scope. If this object emits weak IR ray, it will be submerged among the dark background and difficult to be identified. To resolve the problem, the IR image must be enhanced and preprocessed. The thermal imaging camera allows an image mode to be preset according to the temperature distribution differences of a specific environment or scenario so as to highlight the object:

B Common Emission Rate
Emission Rate
The emission rate is the capability of an object to emit or absorb energy. An ideal transmitter provides an emission rate of emitting 100% of intake energy. An object with an emission rate of
0.8 can absorb 80% of intake energy, and reflect the remaining 20%. The emission rate is the ratio of the energy emitted by an object at a specific temperature to that emitted by an ideal radiator at the same temperature. The range of emission rate value is 0.0 to 1.0 generally.
