Since their inception for use by the U.S. military in the
forests of Korea, infrared cameras have been put to use in any
number of industries - from medicine to geological surveys.
They've also grown into a pivotal tool in home security
surveillance, rendering security systems complete in a way
never before thought possible.
People these days often don't fully understand the
difference between 'night vision' security cameras and infrared
technology. Night vision cameras predate infrared - in fact,
night vision goggles, which use an array of lenses to intensify
light up to half a dozen times what the human eye could
perceive, were already in use during World War II. More modern
variants use CCD lenses sensitized to light at Wavelengths
invisible to the human eye. Such cameras incorporate a torch
that shines light at that wavelength, effectively illuminating
the scene for the camera while it appears unchanged, even pitch
black, to human eyes.
Both these designs are known for producing images of
inferior quality. Much of the time, the resultant footage is
monochromatic, fuzzy and about as clear as the imagery you'd
expect from a video game console in the 1980s.
True infrared security cameras do not provide any
illumination of their own. Instead, they read and record the
black body radiation of objects. This radiation is brought
about by the heat emitted by objects, and as such can be
detected totally independently of lighting conditions by use of
the camera's microbolometer. Of course, the imagery they
produce doesn't look much like ordinary video footage - it's
not going to tell you the color of a person's hair, skin or
clothes. What it will do is assist you in determining their
height, build and gender, what they did and where they might
have left any traceable evidence such as fingerprints. What's
more, adding this state of the art technology to your home
security surveillance system needn't force you into completely
rewiring your pad. The existence of wireless surveillance
cameras of the infrared type means that you can have any
footage captured transmitted to a remote location, and thereby
uploaded to a storage cluster online, where you can view it
through a private website.
Infrared security cameras can be an invaluable addition to
homes where poor outdoor lighting conditions render ordinary
wireless surveillance cameras insufficient. While their images
might be hard for a layperson to interpret, they provide what,
for a skilled thermographic analyst, amounts to full-spectrum
coverage.
Thermal cameras from FLIR, the leading manufacturer of
infrared security cameras in the world, start at about $2000.
Since even the most basic model is, obviously, a substantially
pricey piece of technology, you should do a thorough evaluation
of your home to determine if an infrared security camera is
even really necessary. If you live in a very well lit area with
good visibility even during the night, an ordinary wireless
surveillance camera should do the trick. You can further
eliminate the need for infrared security cameras by having
motion activated lighting on all sides of your home (instead of
just in the standard location by the driveway or front
door).
Lest I paint too dark a picture, however, you should know
that infrared security cameras can help you save money on some
fronts. For instance, if you properly programmed, they can
render the need for smoke detectors null and void. If set to
raise the alarm when ambient temperatures exceed certain safe
limits, infrared cameras can act as very serviceable fire
detectors.
