Technical Parameter Analysis


The resolution of a thermal imaging camera refers to the level of image detail it can display. Usually expressed in pixels, higher resolution means clearer images. Common resolutions for thermal imaging cameras in the market include 320x240, 640x480, etc. Higher resolution typically implies clearer images but also comes with higher costs.


The sensitivity of a thermal imaging camera refers to its ability to detect temperature changes. The higher the sensitivity, the smaller temperature differences the thermal imaging camera can detect, providing more accurate images. For some applications such as industrial inspections and medical diagnostics, high sensitivity is crucial.

Temperature Range

The temperature range of a thermal imaging camera determines the range of temperatures it can measure. Different application scenarios may require different temperature ranges. For example, some industrial applications may require measurement of extremely high or low temperatures, while others may only need to measure temperatures within the normal range.

Functional Features

Image Enhancement Technology

Thermal imaging cameras typically use image enhancement technologies to improve image quality. These technologies may include digital detail enhancement, dynamic range adjustment, etc., to optimize contrast, clarity, and color in images.


Usability is an important consideration in the design of thermal imaging cameras. Excellent user interface design and ease of operation can enhance user experience and reduce confusion and misoperation during use.

Connectivity and Compatibility

Modern thermal imaging cameras typically feature multiple connectivity interfaces such as Wi-Fi, Bluetooth, Ethernet, etc., to support connection and data transmission with other devices.
