Infrared light is visible with video cameras, it does often synonymous variant of the green Nightshotprogramme of camcorders.
UV Color is only with a corresponding visible light, and then synonymous for both people and for the Camera.

@ Scrow
You need a little perspective, because only some cameras have an "interruptible" filter for IR / UV.
In the vast number of cameras is a quartz glass with a layer overlying layer of silicon nitride on the image sensor, the better color separation and to increase the Aussteuerungsbereiches serve.
In the IR range, for example, up to 1.1 micron spectral components of the oppressed.
On most cameras will be all feasible steps to ensure they do not apply to the human eye visible areas
not be transferred.
You will therefore Camera you need, when you can Befilterung off.
