I want to protect my
home and use Security Cameras
So I want to protect my home. I need a video
surveillance system for night or in areas with low light. So looks like the
best option would be infrared security cameras that capture images even in the
dark.
So what is an infrared camera exactly?
An infrared camera works by calculating the brightness of a
room or particular area. They feature special LED lighting which can be seen on
the outside lens. These LEDs are able to capture light from the regions of
electromagnetic spectrum that allow an image to be created even if there is
little visible light. For this reason we refer to IR cameras as having night
vision.
An infrared security camera will switch its mode to infrared
only when the light drops below a certain level. It captures black and white
images at that point.
Interesting side note, IR Illuminators allow many objects to
be penetrated, such as the haze, fog and smoke. Infrared Illuminators are used
typically for a low light environment. Sometimes, when the IR array is focused
narrowly or the hold is not strong enough the external IR Illuminator will give
an extra sharp image. It can provide an additional infrared light source that
is invisible to the naked eye normally.
