Can I use a Night Vision device in extremely low light, or absolutely no light conditions?
Yes you can use night vision devices in extreme low or absolutely no light condition. They have infrared light which invisible to the human eye but it helps in night surveillance. Axton is the company which manufactures different infrared cameras. For more details visit

Yes. While it is true that your Night Vision device needs some available light to work, it is still possible to see a bright image in low light or no light conditions with the use of an Infrared Illuminator, which can be either built-in or attached to the device. On most of our products, the Infrared Illuminator is either standard, or available as an option.
