TO SEE IN THE DARK

The power of vision has found so many applications, even in the most unlikely of places. Modern technology has allowed us to harness the power of vision and see in places and times where it was not possible before.

An example is the night vision security camera. This camera makes use of a special lighting technology that allows it to see even in very a dark environment. A night vision security camera is very useful to use in places like museums and libraries where the use of bright lights can be damaging to the artifacts that are stored there.

Another useful application of a night vision security camera is for military and surveillance purposes. You can install night vision security camera in strategic places to monitor movement and suspicious activities without them knowing that they are being watched.

HEAT VISION

Usually, a night vision security camera makes use of thermal lenses to detect heat rather than colors. Because in a dark environment there is no light to help differentiate hues and shapes which makes sight possible, using a light dependent lens is useless. A night vision security camera employs a sensor that detects temperature differences between objects. This thermal lens then calculates the difference between the temperatures and translates these differences into a form that is recognizable by the human eye.

When we are looking through a night vision security camera, what we usually see is a mass of light color moving against a generally dark background. From the color differences it can be very easy to deduce if the moving object is human or animal.

Of course when using a night vision security camera, it is better to use it with a healthy amount of discretion. While night vision allows us to see the presence of another human, we have no way of discerning whether the presence is friendly or not.
