Animals in nature are a natural heating body just like the human body (with some exceptions). Changes in the body such as injury and disease often lead to changes in body temperature. For a long time, people's research on animals has been limited to the methods of visual assessment and manual measurement and the analysis of components in the body, which is not accurate enough and efficient. Infrared thermal imaging technology uses a non-contact method for animal research, which can monitor in real time and save research time.

Thermal imaging cameras offer the following advantages in animal research:

1. Non-invasive observation: Infrared thermal imaging cameras can observe animals in a non-contact manner without direct contact or interference with animals. In this way, the disturbance to the animal's behavior and physiological state can be avoided, maintaining its natural state, and providing more real and reliable data.

2. Real-time monitoring and continuous recording: The thermal imaging camera can monitor the animal's body temperature distribution and heat emission in real time, providing continuous recording and observation. This allowed the researchers to capture changes in an animal's body temperature over time and under environmental conditions, and analyze its effects on behaviour, physiology and health.

3. Non-visible light observation: Infrared thermal imaging cameras can detect infrared radiation on the surface of animals, which is a kind of non-visible light. Through infrared thermal imaging cameras, researchers can observe the thermal energy distribution on the animal's body surface, revealing information about its thermal regulation mechanism, activity patterns and environmental adaptability.

4. High spatial resolution: Modern thermal imaging cameras have high spatial resolution and can capture subtle temperature changes and hot spots. This allows the researchers to observe localized temperature differences on the animal's body surface, and to better understand the details of the animal's behavior, physiology and metabolism.

5. Large-scale observation: the thermal imaging camera can cover a large observation range, from a single animal to a group of animals or even a larger area. This allows researchers to simultaneously monitor body temperature changes in multiple animals and study aspects of their social interactions, group behavior, and spatial distribution.

6. Multi-disciplinary application: Infrared thermal imaging cameras are widely used in many disciplines such as ecology, behavior, physiology and animal health monitoring in animal research. It provides a wealth of data for different research fields, helping researchers gain insight into the ecological adaptation, behavior patterns, energy metabolism and health status of animals.

In general, thermal imaging cameras have the advantages of non-invasive observation, real-time monitoring and continuous recording, non-visible light observation, high spatial resolution, large-scale observation and multidisciplinary application in animal research. These advantages provide researchers with powerful tools to help them reveal important information about animal behavior, physiology and ecology.
