How Far that Thermal Camera Can See?
To understand how far a thermal camera (or infrared camera) can see, firstly you need to know how big size the object you want to see is. Besides, what is the standard of "seeing" you define exactly?
Generally speaking, the "seeing" would divide into several levels:
1. Theoretical maximum distance: as long as there is one pixel on the thermal imaging screen to reflect the object, but in this case, there will be no accurate temperature measurement
2. Theoretical temperature measurement distance: when the targeted object is able to measure the accurate temperature, it generally needs at least 3 pixels of detector reflected on the device, so the theoretical temperature measurement distance is the amount that the object can cast 3 pixels on thermal imaging camera.
3. Only observation, no temperature measurement, but identifiable, then this requires a method called the Johnson Criterion.
This criterion includes:
(1) fuzzy outlines are visible
(2) shapes are recognizable
(3) details are recognizable
Maximum imaging distance
= number of vertical pixels × target size (in meters)×1000
Vertical field of view×17.45
or Number of horizontal pixels × target size (in meters)×1000
Horizontal field of view×17.45

How many type of thermal camera at present?
2022-12-24 - Technical Discussion According to different uses, thermal camera can be divided into two types: imaging and temperature measurement: imaging thermal imagers are mainly used for target tracking and monitoring, and are mostly used for national defense, military, and field monitoring.
What’s the Difference between Infrared Thermometer and Thermal Camera?
2023-02-01 - Technical Discussion This article, it is talking about the five main differences between an Infrared thermometer camera and a thermal camera. The infrared thermometer only has a single-point measurement function, while the infrared thermal imager can capture the overall temperature distribution of the measured target.

Basic Principles Of Infrared Thermal Imaging Technology
2023-11-03 - Design Article Infrared thermal imaging technology can collect the overall temperature distribution data of the appearance of the equipment in service. It has the advantages of accurate temperature measurement, non-contact, and long temperature measurement distance, and judges whether the equipment is operating normally through the measured thermal image characteristics.
