How far that a FLIR camera can see?

The range of a FLIR (Forward-Looking Infrared) camera, or thermal imaging camera, depends on various factors, including the specific model of the camera, the environmental conditions, and the size and temperature difference of the objects being observed. Thermal cameras work by detect infrared radiation emitted by objects, which allows them to create thermal images based on temperature variations.

In general, FLIR cameras have a range of a few feet to several miles. However, it's important to note that the level of detail and accuracy of the thermal image may decrease as the distance increases. Factors such as atmospheric conditions, humidity, and the presence of obstructions can also affect the camera's range and image quality.

Higher-end FLIR cameras with advanced features and lenses may offer greater range and image clarity compared to entry-level models. Some specialized FLIR cameras, such as those used in aerial surveillance or military applications, can have significantly longer ranges, reaching several miles or more.

Here are some examples of the maximum distances that different types of FLIR cameras can see:

• A FLIR MWIR camera with a 100mm lens can see objects at distances of up to 1 kilometer.
• A FLIR LWIR camera with a 200mm lens can see objects at distances of up to 2 kilometers.
• A FLIR thermal zoom camera with a 1000mm lens can see objects at distances of up to 10 kilometers.

It is important to note that these are just estimates and the actual distance that a FLIR camera can see will vary depending on the specific conditions.

It's always recommended to consult the specific specifications and user manual of a FLIR camera to determine its effective range and capabilities for your intended application. Additionally, environmental conditions and the size and temperature of the objects being observed should be considered when assessing the effective range of a FLIR camera in a particular scenario.
