infraredness
The color light that is optimal for enhancing the performance of a night vision camera is infrared light.

A thermal camera detects heat emitted by objects and displays it as a color image, while an infrared camera captures infrared radiation and converts it into a visible image. Thermal cameras are used for detecting temperature variations, while infrared cameras are used for night vision and detecting objects in low light conditions.
No, the canon powershot does not come with a nightvision mode. Inclusion of infrared and, quite expectedly, thermal vision is both cost and size prohibitive for a standard consumer-level device.
Some night vision goggles detect the infrared signatures of people and objects. Heat travels from a fireplace as infrared radiation.
"Most night vision cameras have what is called infrared night vision. When you are taping something at night, it shows heat as a different color. There is also thermal." A2 Most modern hand held video cameras have a night mode. This uses an LED Infrared floodlight, mounted on the front of the camera. (Ususally behind a red lens cover). This lights up the subject at close range, with infrared light that is invisible to the naked eye. All video cameras are sensitive to infrared (they can see the light put out by a remote control). Night mode is usually in monochrome, black and white or green and white.
No, night vision is the ability to see in low light condition and infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging, are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
Night vision cameras convert ambient light photons into electons. Those electrons are amplified by an electrical and chemical process and converted into visible light.
Electrical predictive maintenance with an infrared camera can save money, downtime and ... Night Vision Goggle like the AN/PVS-7 head mounted dual eye system, ... to the point where they are affordable to just about any company out there
wireless spy cameras with night vision are available. check the website :http://www.intelspy.com/ and you will find (W5802X1 with 5.8Ghz 30-LED Infrared Security Camera for Night Vision - Super Long Distance) price is $51.95
infrared spectrum
Infrared waves are used for night vision apparatus to detect heat emitted by objects or living beings in the dark. Night vision technology converts infrared radiation into visible images, allowing users to see in low-light or completely dark conditions.
