Low light level television
, initialized as LLLTV, is a type of electronic sensing device, usually a CCD
camera sensitive to wavelengths above the normal "visible" (0.4 to 0.7 micrometre) wavelengths, and into the short-wave Infrared
- usually to about 1.0 to 1.1 micrometres. This allows viewing of objects in extremely low light levels, where they would not be seen by the naked eye. LLLTVs tend to be more affordable than infrared cameras, which typically cover ranges from 3 to 5 µm (MWIR)or 8 to 12 µm (LWIR)

Charge-coupled device
A charge-coupled device is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time...

Infrared
Infrared light is electromagnetic radiation with a wavelength longer than that of visible light, measured from the nominal edge of visible red light at 0.74 micrometres , and extending conventionally to 300 µm...
