SECTION 1: INTRODUCTION
Infrared Imaging
Visible light, the rainbow of colors that can be sensed by the
human eye, is electromagnetic radiation within a certain
frequency band. ‘Infra-‘ means ‘below’ and ‘red’ is the lowest
frequency in the visible spectrum. Hence, ‘infrared’ (or ‘IR’)
refers to that range of electromagnetic wavelengths just below
that capable of sight by the human eye. In the IR range,
energy from a scene is not sensed by sight ‘light but rather by
temperature.
Most objects that you see are not radiating visible light but
instead, are reflecting light radiated from another source.
Most objects have to be heated to extreme temperatures before
they radiate energy in the visible light spectrum. However,
energy in the infrared range is being
radiated by all objects
that are above absolute zero (-459F). Hence, everything has a
thermal signature, regardless of light conditions.
Your TSC4500 infrared detecting system distinguishes
between very small differences in thermal (infrared) radiation,
converts it to electrical signals, amplifies those differences,
and reproduces them correspondingly in the visible light
(video) range. Powerful advantages are achieved in being able
to turn a pitch black night into a black and white TV image of
the scene. As your infrared knowledge and experience grows,
further applications will develop as you recognize heat clues
beyond the naked eye in both day and night conditions.

family of un-cooled infrared camera product lines. The
TSC4500 utilizes amorphous silicon bolometer technology in
a Long Wave Infrared (LWIR) camera designed as a drop-in
replacement for CCTV cameras for new and existing security
systems. The TSC4500 provides the advantage of viewing
