The
infrared illuminators of the infrared camera allow the camera to see
fine video images in the absolutely dark areas. In a very small
amount of light, infrared camera can form an image that looks just
like photos taken during day time.
Like
a common camera, the main function of an infrared camera is to
construct an image using visible light. The only difference between a
usual camera and an infrared camera is that the latter one uses
infrared radiation to construct a picture. Infrared security cameras
have infrared illuminators that are installed around the outer side
of the lens of camera. Infrared light is originated from different
areas of the electromagnetic spectrum.
Infrared
security camera and its uses
The infrared security cameras are
frequently used for commercial purposes that turn lights out at
night.
Infrared
security cameras are basically designed to see at the night time.
For this reason, this type of camera often confused with the Night
Vision cameras. However, different wavelength of the light is used
for these two different cameras. Night vision goggles are
extensively used by the military forces. Infrared security cameras
use an unseen light during operation, but the light looks as a white
visible light while viewing on video monitor.
The
video image produced by the infrared cameras is generally black and
white. But nowadays color cameras have also come into existence to
provide better picture. Some of the day/night infrared cameras not
only form color pictures but are also capable of constructing color
videos during the daytime when natural light is accessible and
automatically switch to black and white images while the light is
low during the evening or night.
Some
Infrared security cameras are there that allow people to watch
images at a very low light and in absolutely no light conditions.
You can take pictures both the inside and outside of your house
anytime of the day you like.
In
earlier days, Infrared security cameras were usually very much
expensive. Common people could not even dream of buying an infrared
security camerafor
the safety of their household. But nowadays, infrared cameras have
become quite affordable and even common people can easily get one for
their households. There are various types of infrared cameras are
available in market and the prices of these cameras vary according to
the inbuilt features of the cameras and the popularity of the brands.
