About Infrared Cameras [2010-11-24]
Infrared cameras are sometimes referred to as night vision cameras because of their ability to capture objects in complete darkness. Humans aren't able to see infrared light because it lies in a different range of the electromagnetic spectrum than visible light, which is discernible to the human eye. Infrared cameras operate using infrared LED lighting installed on the outside lens of the camera. This allows the camera to capture and record images in the absence of regular lighting. If the area is slightly lit, the image is clear as if it were daytime and the picture is captured in color....

Photography is all about light. We do many things to produce good photos, but in the end, the light dictates the result of the picture. Infrared light is all around us; we just can't see it. But many digital cameras can. Using an infrared lens, which filters out varying degrees of wavelength light, is one way to produce unusual and interesting photographs. Point a TV or VCR remote at your CCTV camera and push a button on it. If you see the infrared beam through the viewfinder, then you can use your camera to shoot in infrared with the proper lens. Buy an infrared lens for yo...
What Are Infrared Cameras Used for? [2010-11-22]
Infrared cameras, also known as thermographic cameras, take snapshots by capturing images from the infrared spectrum; in other words, infrared cameras take pictures of heat radiation rather than visible light radiation. When taking an infrared picture, the hottest areas of the image glow white, bright red and orange; the darkest portions are dark blue, purple and blackish. The ability of these cameras to "see" heat signatures makes them useful in a variety of settings. Emergency ResponseFirefighters occasionally employ infrared cameras to look for hard-to-see hotspots through s...
