Buying Guide for Thermal Cameras

While you might assume that flashlights are enough, they tend to attract attention. Meanwhile, although night vision can work well, animals may remain concealed enough that detecting them will be next to impossible. The good news is that there is something they won’t be able to hide and that is none other than their heat signatures. 

A thermal camera is an unbeatable and high-tech solution perfect for hunters who stay in the wild after dark.  Instead of seeing the light reflected by the objects, a thermal camera sees their emitted heat. The animals’ body heat glow on the cover even through cover and when the night is already pitch black. 

It is why it is not a surprise that more and more hunters are using these special cameras. But, how does a thermal camera work and how do you choose one?

How Does a Thermal Camera Work?

A thermal camera detects the infrared radiation emitted by objects. These cameras can also detect the radiation they transfer or reflect to objects. These cameras don’t necessarily display the actual temperature of objects in view. Instead, they use algorithms to get approximates of the three values namely emitted, transmitted, and reflected. The displayed image is then built from these values.  A thermal camera’s infrared sensor works just the same with PIR sensors found on motion detectors and trail cameras. 

Battery Life

A thermal camera is similar to trail cameras as it uses various solutions for power needs. There are some that feature enclosed Lithium-ion batteries that recharge similar to the cordless drill. Some also use disposable or replaceable batteries.
