IR-CAM is a digital camera amended by our experts, which allows you to see the writing of special pens containing an invisible ink. Pens are included with the camera.
These inks are completely invisible to the human eye yet can be seen by using special devices which can see in the infrared range, such as our modified camera. These inks do not fluoresce in the visible range, cannot be seen with ultraviolet lights and cannot be seen by the human eye alone. The human eye can see from about 400nm (violet) to about 700nm (red). The human eye cannot see below 400nm or above 700nm. Below 400nm is the ultraviolet range and above 700nm is the infrared range.

The ink does degrade under the ultraviolet rays of the sun in about 1 week. If the object marked is kept covered or away from the sun, the ink last a much longer time.
