What's more, intelligent analytics on these

Video surveillance
imaging in little to no

T
hings that go bump in the night
have finally met their match.
There's no need to guess what's
lurking in the darkness - breakthroughs
in video surveillance technologies
now enable thermal and nightvision cameras to
capture high-quality images in little to no light.
More good news - advancements in heatbased
imaging have not only become more reliable,
but exponentially more affordable.
With the proliferation of these thermal and
nightvision technologies and trickle down of
their capabilities into midlevel as opposed to only
very high-end cameras, myriad applications have
been emerging. This is paving a clear pathway for
installing integrators to expand their video surveillance
repertoires and increase their revenues.
Breakthroughs Breed Better Imaging
As Jatin Patel, solutions engineer, Axis Communications,
points out, new sensor technology
is among the most significant advancements
in thermal cameras. New sensors offer better
resolution and more advanced capabilities that
give thermal cameras great surveillance advantages
when there's no source of light available
in a scene, he says. " Greater resolution pro48

The sensitivity of thermal cameras also continues
to improve, which, in turn, enhances
the accuracy of detection at long distances. As
Chris Johnston, regional marketing manager
- video systems for Bosch Security and Safety
Systems, explains, " Greater sensitivity provides
more details of an object, making it easier to
classify the object to determine if it is a possible
threat, such as a person, or nonthreatening -
such as wildlife. "
Rui Barbosa, product manager, i-PRO
Americas, cites the ability to reproduce accurate
color in extremely low light environments
as the most significant technological advancement.
" Not only can we see color in low light,
but there is also the ability to accurately capture
color, " he notes. " And traditionally, in a 0 lux
environment, there is no light visibility. While
infrared illumination [IR] is used by many
manufacturers, the best systems include the
ability to control the IR intensity based on the
scene. For example, lower quality cameras will
produce overexposed or incorrectly exposed
images where a close-up object cannot be distinguished, "
he adds. " Higher quality cameras
can adjust the intensity of the IR light to provide
the best possible image. "
All these recent strides in thermal and nightvision
cameras are providing end users with
benefits they previously couldn't leverage. End
users typically deploy thermal cameras for early
detection of potential risks, Johnson contends,
because they want to know as soon as possible
if there is a risk to the area or assets they are
protecting so they can respond faster.
