How to Choose a Thermal Imaging Camera?

Answer 1

Since the first prototype was unveiled in 1992, use of thermal imaging cameras has expanded into not only the military but civilian fields, as well. Before investing in the high-tech equipment, determine which model configuration is best suited to intended use: a hand-held thermal imaging camera (TIC), a helmet-mounted one, or a vehicle- or object-mounted model.

Similar TechnologyBoth model types use the same technology: manipulating infrared radiation into visible light, and both have the same purpose: identifying sources of heat or heat signatures. Both adhere to the same performance standards determined by the National Institute of Standards and Technology in the US. Which configuration would suit better depends on other needs. Hand-Held ModelsAdvantages of a hand-held thermal imaging camera include transferability from one user or another. The carrying handle usually is of a loop design which allows

easy, hand-to-hand gripping.

Helmet-Mounted ModelsFirefighters and military personnel find helmet-mounted thermal imaging cameras convenient, leaving both hands free for other tasks. While this model type adds approximately 1.5 pounds to the weight of the helmet, the convenience outweighs inconvenience. Usually operated on a pivot arm, the helmet-mounted model can easily be removed from vision with a simple twist and lift motion. Otherwise-Mounted ModelsThermal imaging cameras can be mounted on helicopters, on airplanes, or on ground vehicles. They can also be used in security checkpoints at points of entry such as airports, train or bus stations. Readily identifying elevated temperatures, TICs have also been used to detect possible H1N1 virus-infected travelers. Image TransmittalThe thermal imaging camera detects heat variations, enabling “sight” through darkness or smoke. When it detects a heat signature, the temperature is assigned a color; the image received on a separate monitor reflects the color differences, and the object can easily be identified based on the heat signatures in the surrounding area. SummaryKnowing the advantages and disadvantages of each model type maximizes operational satisfaction. Choosing the least expensive model simply because of cost may well cost even more in dissatisfaction if the model doesn’t meet known operational requirements. Consider the operational environment, versatility, and adaptability, as well as cost when choosing which thermal imaging camera model will best suit needs and budget.
