Many people are beginning to discover the exciting world of being able to see in the dark. If you’re out in the dark a lot, a night vision camera may be of use to you. People who camp or hunt a lot have found a camera with night vision technology to be especially handy for them. For many years the military has used night vision equipment. Current advancements have improved the uses of night vision cameras in areas such as cinematography and photography as well.
To understand how a night vision camera works, first let’s define exactly what night vision is. Simply put night vision is the ability to see in the dark. This can be done either biologically or through the use of technology.
There are two different types of night vision technology. The first works on the principle of image enhancement. It works by collecting the minute amount of light available from natural or manmade sources, and amplifying it to the point where objects can be viewed. It even collects light from the lower end of the infrared light spectrum, which is generally imperceptible to the human eye.
The other way that night vision technology works is through a process known as thermal imaging. This process works by capturing the upper end of the infrared light spectrum. This part of the light spectrum is emitted in the form of heat, as opposed to light as we might recognize it. The warmer an object is the higher amount of this light is emitted.
Night vision cameras provide high quality color video during the day. When the light level drops below a certain point the security camera automatically switches to IR, or infrared, night vision video. When the light level increases to a specific point the camera automatically switches back to color video.
Night vision cameras come in such a broad range of products that it is impossible to discuss price without knowing how the camera will be used. Military and business cameras are going to be used differently than a camera for personal use. The type and length of the camera warranty will affect the price as well. As with all purchases, doing your research and understanding your budget and exactly the reason why you are buying a night vision camera are important considerations before you actually buy the camera.
If being able to see in the dark is a necessity for your career or just something you are learning about in a hobby, night vision cameras may be just what you are looking for.
