Thermal Imaging Camera
New models of thermal imaging cameras are now more affordable to many people compared to when it was just a new technology. The technology used in these cameras is now commonly and effectively used in various business applications, including, but not limited to problem identification, surveillance, analysis and preventive maintenance. A thermal imaging camera weight can vary depending on the model. Features vary as well. Some are high resolution and can produce clear thermal-based images. Since thermal imaging technology requires a high level of science, manufacturers who delve in this technology are usually industry experts. As such, they are more than capable of producing ergonomically designed cameras. This article will focus on the technology behind thermal imaging and the applications to which it is used.
A thermal imaging camera has similar function as a digital photographic camera—it takes pictures. The only difference is that it takes thermal images. Thermal imaging cameras are equipped with detectors, which amplifies and measures the thermal-infrared emissions by the subject. The dimensions of the emissions or radiations or invisible wavelengths are then instantly converted to an image or visual representation. The images are displayed in various colors depending on the temperature. Cooler parts of the subject are displayed in different shades of blue and hotter objects are displayed in various shades of red. These representations, via USB download, are then sent for analysis and formatting in the computer.
If you’re in the market for a thermal imaging camera, it is important to know what features to look for, in order to make intelligent buying decisions. The main features that may vary from one product to another are resolution, temperature range and precision. If you want a more detailed thermal picture, then a high resolution camera may be the one for you. Resolutions are measured by pixels—the more there are in the camera, the clearer the thermal images. As for accuracy, anything at 2% or above is considered high. Thermal range refers to the maximum operational temperatures. If you will be using the camera on very high and very low temperatures, make sure that the camera you’ll choose can still effectively and accurately capture images in these temperature conditions.
A high end thermal image camera offers more features than a standard camera. If you need special functions such as photographic overlays, then, you may want to consider looking at the high end ones. Some other special features include dew point and insulation alarms. They are primarily used by building inspectors and HVAC industries to locate areas with moisture or those lacking insulation. Other high end cameras also offer voice annotation and flashlights.
Due to cost issues, thermal imaging cameras were not widely used before. Industries that could’ve benefitted from its use have to find a more cost efficient substitute. With the availability of low-cost thermal imaging cameras, more and more industries are incorporating it in their businesses. Building inspectors use these cameras to study heat profiles of electrical lines.
HVAC businesses use them in identifying weak points through thermal visual representations of areas that need more insulation or areas that need moisture control. They can also be useful to people in the pest control business. Cameras can easily detect infestations inside walls, enclosed areas and other tight, hard to access spots. People in the military use this on area reconnaissance. It is also a great tool for people in the law enforcement when searching for criminals or when conducting surveillance. Even people who are into ghost-hunting have a use for it. All in all, thermal imaging cameras are functional tools that are starting to become a part of our daily lives.
