Night vision technology is one that has infinitely helped various professionals in their chosen field but is it really possible to hide from this type of imaging technology?. To escape night vision goggles, you first have to know what they do, so as to understand how to avoid them.
How Does a Night Vision Camera Work?
It would be insanely cool if humans were able to see in the dark with our own eyes but unfortunately, nature has eliminated that possibility and we have to rely on handy technology. There are a couple different types of night vision: One that most security cameras use, and one that night-vision goggles use. The most common type that’s used on most security cameras is infrared (IR) night vision, which relies on infrared light. If you’ve ever looked at the front of a security camera, you’ve probably noticed that it’s covered in a handful of small LED bulbs.
This is the IR light, and when it gets dark out, these lights turn on and act as a flood light of sorts, dousing the camera’s field of view with infrared light. The thing is, infrared light is completely invisible to the naked eye. So it doesn’t look like a bright light is flooding the area from the outside, but it actually is—your eyes just can’t see it. Furthermore, night vision footage from security cameras always looks black and white because human eyes can differentiate between black and white better than they can with other shades of colors, like red or blue. Due to this, most night vision cameras switch to a monochrome filter to make it easier for us to see the image.
There is another form of night vision that you may aware of, this makes uses of intensifier tubes and photo multiplied and passed through a phosphor screen which gives a characteristic green glow.
How to Elude this Technology?
Yes, it is possible to hide from night vision camera. We would be discussing two methods and they include:
Military Camouflaging: Scientists have developed various models of military camouflage that’s covered with carefully crafted patterns which reflect infrared lights and blend the person wearing it with the environment. This type of protection doesn’t always work, because of random elements like weather or different environments.
Recently, the researchers at UC Irvine have developed camouflage coating based on a pencil squid that is invisible to the infrared cameras. They based this coating on a protein called reflecting which, with a mixture of chemicals, provides infrared invisibility. Researchers hope that this type of camouflage will have the ability to turn on and off its infrared invisibility, this could be used by the military to avoid sticky situations on various missions.
Thermal imaging: Thermal imaging shown in many action movies and games, however, does not rely on light, it relies on temperature and the only way to hide from it is to hide your heat signature, now we are talking like secret agents. The easiest solution is to cover yourself with a thermal blanket made of Mylar foil. It blocks your heat signature from thermal cameras, but its downside is that it traps your heat beneath the blanket.
This is only a temporary solution because heat needs to escape and without proper heat venting system your cover will be blown. Another problem with thermal cloaking technology is that your heat signature might look too cold on thermal cameras, which can also raise the suspicion.
These are some good ways on escaping night vision with a minimal chance of being caught, I sure am excited to try them out.
