What problems should be paid attention to when choosing an outdoor thermal imager?


With the advancement of people's leisure concepts and the liberalization of relevant national policies in recent years, hunting within the legal scope has gradually become a brand-new way of middle-class leisure. There are more people playing, and natural equipment is becoming more and more particular. A typical case is the application of thermal imaging cameras in the process of searching for animals. So, what issues should we pay attention to when choosing an infrared thermal imaging camera for hunting? Let's see how the editor explained it to you.

Selection method of infrared thermal imaging:

  1. Thermal sensitivity is one of the main parameters of infrared thermal imaging cameras. Thermal sensitivity, as the name implies, is the smallest temperature change range that can be sensed. Generally, the thermal sensitivity of an infrared thermal imager at 30°C is ≤0.05°C.

2. Spatial resolution is also a main parameter of thermal imaging cameras. The spatial resolution is the smallest distance between two adjacent targets that the thermal imager can distinguish.

3. The focal length of the lens is also a main parameter of the thermal imaging camera. The larger the focal length, the smaller the field of view, and the smaller the field of view seen through the lens.

4. "Don't confuse the detector pixels and the eyepiece pixels. Some companies often confuse these two concepts." The relatively high-end products of civilian thermal imaging cameras have pixels of 640×512, and the infrared images captured by this high-end thermal imaging camera are clear and delicate. , Can distinguish objects the size of rabbits 500 meters away.

The above is the infrared thermal imaging selection method shared by Maice Technology. I hope it helps everyone. In addition to the above parameters, the measurement accuracy, window, display and output, and protection accessories of the thermal imaging camera must also be considered.
