What Thermal Cameras “See”
Visible light is the sole aspect of the electromagnetic spectrum that humans can see. Light only occupies a minor area upon the electromagnetic spectrum. Conversely, infrared radiation represents a bigger percentage. Custom equipment is necessary in order to observe what’s happening in other areas of the electromagnetic spectrum.
All objects reflect, absorb or occasionally transmit energy at various levels. Different materials tend to emit cold or heat energy at various rates. Infrared energy detects and displays this energy in the form of images.

A Brief Look at the Applications and Background of Thermal Imaging Cameras
The implementation of thermal imaging cameras traces back to military use as far back as the First World War. Subsequently, other fields continue to find applications for thermal imaging cameras. For example, fire departments can utilize them to locate people in emergency situations. Also, law enforcement applies the technology to conduct surveillance, locate suspects and to investigate crime scenes.
Power line maintenance service techs can detect areas of overheating and prevent possible power failures. In the event thermal insulation materials become faulty, construction techs can locate heat energy leaks to improve efficiency. Thermal imaging cameras are also useful in the home inspection sector.
Thermal imaging cameras are available with basic minimal features that read temperature only. In addition, they are available with several features that permit users to pick multiple crosshairs. They can draw comparisons between images to display low, high and average temperatures. Thermal imaging cameras offer several color palettes, too. For instance, the “iron” palette is frequently chosen by home inspectors. Or, the black/white palette serves to identify specific details of an image. The rainbow palette offers optimal thermal sensitivities for showing the differences among temperatures.
There are many components that play a part in the quality and the price of thermal imaging cameras. The most critical factors are typically thermal sensitivity and detector resolution.

The detector resolution displays the number of pixels. The most typical resolutions are 160 x 120, 320 x 240 and 640 x 480 pixels. A 320 x 240 detector shows images of 76,800 pixels. Higher resolutions also result in visibly sharper images. Thermal sensitivity is basically the narrowest temperature difference the thermal imaging camera may detect. Another important issue to take into account is the thermal imaging device’s temperature range. The range indicates what the lowest and highest temperatures are that the device can measure.
To get the best thermal images for analysis, there are some adjustments that can be done to most thermal imaging cameras. For example, adjustments to focus, thermal tuning and reflective temperature settings. Users can consider each of these adjustments when choosing a thermal imaging camera.
Just like a conventional camera, the lens of thermal imaging cameras require proper focus to enhance the image clarity. It’s possible to focus many cameras by simply twisting the lens. Other models feature a push-button focus.
Another aspect to consider is emissivity, which is the amount of radiation an object emits. Emissivity adjustment is important when doing temperature measurements or for comparing temperatures of two separate objects. Not all cameras permit users to input reflective temperatures. Thermal tuning a camera entails adjusting the temperature range which the camera “sees” while in manual view mode. Manual mode enables the user to adjust to a specific range. The camera displays this temperature span. Utilizing the manual viewing mode is optimal for detecting temperature differences.
CAMERAS BASICALLY ENABLE PEOPLE TO SEE WHAT THEIR EYES CANNOT
They can detect heat radiation – which is invisible – that all objects emit regardless of light conditions. Some of the key benefits to thermal imaging are in the form of the security they provide. Security cameras are a standard protection feature for many businesses across Chicagoland.
Certainly, the need for producing quality images is essential for protection against intruders.
When cameras monitor a building’s perimeter, they frequently must contend with low light. (Naturally, during nighttime.) This is when thermal imaging cameras are so useful.
Less false alarms
Thermal imaging cameras frequently provide cost-effectiveness in business protection settings. This is because they help diminish the frequency of false alarms. Advanced analytics software accomplishes this because it produces high contrast photos and videos.
No visual limitations
A positive return on your investment
Conventional cameras that see visible light only are vulnerable in some cases to getting “fooled” by visual camouflage. Or in settings where like colors blend in together. This tends to make it difficult for conventional cameras to detect people or objects.
