Thermal Imaging against Iray Night Vision

During the night are the most difficult and hazardous moments for us since our eyesight is greatly hampered by the darkness; yet, for those who have to carry out their tasks in the dark, night vision is nothing out of the ordinary to them. In the past, it was a military-grade tech that is now used for spy films and undercover equipment. The question is, what precisely is night vision, and how does it differ from other hot items?


How does night-sight work?

Night vision equipment employs identical tech as regular cameras but at much higher magnification. The device’s apparatus is able to scan nocturnal environments and capture all light that can be seen. These lights are subsequently amplified and shown as greenish-hued pictures. Another name for night-sight gadgets is “picture intensifiers.” From a personal standpoint, it is a better, more detailed description for them as the conjoining term “night vision devices” can be applied to image magnifiers, infrared cameras, and thermal imaging because all of them are used to see at night.


How does Thermal Imaging work?

Thermal night vision, also known as infrared (IR) imaging, is a tech that detects the thermal signatures of objects using strong heat sensors. It transforms the heat signatures into a visual thermal image, with the higher heat signatures emphasized in a lighter color. This makes the objects easier to observe as the great contrast from various areas is intuitive in the image. This tech has a wide range of uses HVAC testing, observing the environment, thermal hunting, etc.

The biggest advantage of infrared imaging gadgets is that they do not need any external source of light and can be used in challenging weather conditions such as sandstorms, downpours, smog, etc. The thermal imaging device is able to show trustworthy, sharp images in most cases. As a result of this ability, it is the most popular night vision technology. It distinguishes it from the rest of its competition, making it unmatched.


Thermal Imaging vs Night vision

The main distinctions between the two are the following:

  1. Firstly, thermal imaging requires no light source differentiating it from night vision that in order to operate correctly requires visible light in close proximity
  2. Thermal imaging uses thermal detectors to find temperature variations between objects. Meanwhile, night vision magnifies visible light that is near.
  3. The next difference is that night vision is limited by outside factors like the weather (storm, dust, fog, etc). Thermal imaging can be used in all weather conditions.
  4. Thermal imaging transforms thermal signatures into strong visual pictures, where objects with greater thermal signatures appear brighter yellow, orange, or red. In comparison, night vision enlarges the light in a picture and converts it to green-tinted pictures
  5. Lastly, night vision is a technology of the past. It is still useful in some situations, and it is less expensive than other solutions, but the visual quality is inferior. On the other hand, thermal imaging is a fully advanced technology and although now it is more costly than other solutions, it improves your visibility at night. Also, it is becoming more affordable.


If you are planning on buying night vision equipment, you should choose a thermal camera that is capable of more than simply night vision:
