What Is A Thermal Imaging Camera?

Sper Scientific Thermal Imaging Camera (800201) combines a high precision thermal images with a standard photo for maximum clarity.  With a press of a button, the thermal image can be blended in increments of 25% on a beautiful 3.5” LCD full color display.  This unique feature is ideal for both DYI and professionals such as building inspectors.

What is a Thermal Imaging Camera? Thermal Imaging Cameras are used to see temperature events behind walls or other solid objects to detect overloaded breaker boxes, missing insulation, and water damage as well as many other items. Being able to “see” behind walls as well as detecting large temperature differences can help stop thousands and in some cases hundreds of thousands of dollars of damage to expensive equipment and homes. Homeowners, Inspectors, electricians, contractors, and auto mechanics are just a few of the people who can make use of Thermal Imaging Cameras.

Resolution is the most important factor indicating quality of thermal imaging cameras. The higher the resolution, the more precise and accurate measurements of small targets are going to be. Sper Scientific’ 800201 has a resolution of 220 x 160 with a visible image resolution 35,200. This resolution would put this model between the Flir E6 and E8 as far as resolution is considered.

Keep in mind, thermal camera displays might have more pixels than a camera detector, but your actual thermal image is always limited by the thermal detector resolution. You should think of it as up-scaling on your 4K TV. Your TV might have 4K resolution, but if the source (let’s say DVD player) is only 480P, you are only seeing an upscaled image.

Temperature range is an important factor to consider as well. For home use and DIY types a range of 14 to 300°F is more than adequate for almost all scenarios as this will allow you to spot unsealed windows, potential water leaks, and Heat/AC issues. For professional use in factories or inspections you will need a higher range such as -40 to +50 °F as this will allow you to spot check heat spots on active machinery that may operate normally at higher temperatures that 300°F.
