How to Best Calibrate Your Thermal Imaging Camera?

How to Best Calibrate Your Thermal Imaging Camera?

A thermal imaging camera must be well-calibrated, right from the onset. Using an uncalibrated one is like using a saw with blunt teeth. Make no mistake about it. Think of it as you would a 12-inch ruler, or one foot. Every grader in America knows what a ruler is. However, truth be told, not everyone knows one inch used to be a rough estimate. And that exactly shows why making sure you’re using a standard method of measurement in your thermal inspection is wise. Or you’ll end up shooting yourself on the foot. Now, the word inch comes from the...

Thermal Camera: What is Black Body?

Thermal Camera: What is Black Body?

A black body is one of those concepts in physics that is extremely useful in thermography. In fact, it is a cornerstone of infrared imaging. Keeping a tab on the black body radiation of an object has expanded infrared imaging to greater heights far more than we can imagine.  For instance, by keeping black body radiation as a reference, astronomers can determine the birth of stars and the formation of a black hole in space. Indeed, it’s not an everyday concept. But taking time to wrap your head around the nitty-gritty of a black body can help push the envelope...

Security at Its Finest: The Merits of a CCTV Thermal Camera

Security at Its Finest: The Merits of a CCTV Thermal Camera

A CCTV thermal camera is security at its finest. By showing capabilities far beyond the powers of traditional visible-light cameras, an infrared imaging camera  (IR camera) pushes the envelope in early detection and crime prevention to greater heights. For starters, thermal cameras allow people to see beyond what their eyes can see. This means you can detect intrusion even in the dead of night. Moreover, not even the thickest of fog or snow can deter one from knowing someone is dangerously approaching —  lurking behind the confusion with possible criminal intent. As you may know by now, when it comes...

How Does a Thermal Camera Work?

How Does a Thermal Camera Work?

Indeed, a thermal camera (a.k.a., infrared camera) sees far beyond what our human eyes can see. By doing so, it can give us unmistakable signs of the birth of a star hundreds of thousands of miles away. Had we relied on just visible light (e.g., smartphone camera), we would miserably fall short. And fumble. In fact, Hubble Space Telescope, as powerful as it is, won’t be able to detect such a groundbreaking moment. NASA’s low-orbit space telescope might be able to give you a spectacular image of a beautiful nebula far, far away. And yet, it won’t give us a hint...

Thomas Seebeck and the Thermoelectric Effect

Thomas Seebeck and the Thermoelectric Effect

To boot, a thermocouple is indispensable to humanity. As the most widely used temperature sensor on the planet, it’s as indispensable as the tools we use every day which operate them. Think about it. We’re talking about thermostats, ovens, and steam kettles. And that’s just for starters.  It’s true, thermocouples may not be on the radar of consumers and ordinary Americans. But if you talk about getting the temperature of the hottest materials on the planet, say the temperature of the insides of a volcano (1,250°C or 2,200°F), you’re going to find yourself in an extremely tight situation if you...
