What is thermal imaging cameras? A thermal imaging camera or an infrared camera less exclusively, is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light.

Sometimes it is also called a FLIR (Forward Looking InfraRed) camera. Thermal Imaging Cameras function to a great extent like digital photographic cameras but they take a thermal picture. First of all detectors measure infrared radiation which is then changed into electrical signals in order to generate a visual image of the heat an object gives off. The visual image displays cooler items in shades of blue and hotter items in shades of red and can be analyzed and formatted on a computer through a USB download.

When deciding on a thermal imaging camera, the primary features to consider include the resolution, accuracy and temperature range. The resolution is deliberate by pixels. Because every pixel on the screen represents a discrete temperature reading, the more pixels the camera has the more features the thermal picture will be. Accuracy is measured in terms of a percentage of the value of the reading. Commonly the majority cameras have accuracy's between 2-5%.

Finally, thermal cameras are restricted to a particular temperature range. If you want to deals with extreme heat or cold, you should make sure the camera is able of taking those measurements. Thermal imaging cameras cost as little as $3,000 making them an economical analysis and diagnostic tool for a number of professions.

How are thermal imaging cameras used for building inspections? Thermal imaging is a method in combination with a moisture detecting meter is a new technique of detecting symbols of moisture ingress inside the wall before the moisture mark becomes detectable to everyone. Regular checking of your home’s walls must be necessary to avoid the damage of your walls. Thermal imaging mechanisms not only provide safety to the wall of your home, but also protect your work place from various kinds of damages. Undetected moisture behind your walls can deteriorate the woodwork and cause structural integrity issues in a given area.

Now a day’s infrared inspections and surveys are progressively more requested for residential, industrial and commercial applications. Using a local certified thermal imaging inspector to scan your home for signs of moisture could be the best savings you could make in your home. A moist damp home is usually an unhealthy home. Ask yourself this... "Do I honestly know if there is moisture ingress in the insulation and/or wall cavity in my home that could be affecting my health?" If you answered "no," then it may be in your best interest to type these words into your google search engine "Building inspections using thermal imaging cameras" to find out more. Most home owners think that thermal imaging cameras are used on helicopters for car chases at night. This assumption is correct, but now infrared thermal imaging cameras have been used to perform non-invasive leak and heat loss inspections on your home! It's fast, capable and could save the equity in your home from being absorbed into repair costs caused by late leak detection.  So for a healthy home you should inspect your home with "Thermal imaging cameras".
