What is the difference between night vision and infrared?

Infrared can be used in any area regardless of light condition since it detects heat. Night vision needs light, even a small amount, to amplify in order to see objects in the dark.

Night vision is to see in the dark with goggles which are designed to see in dark, and IR is an advanced technique to see in the dark with the help of IR devices. They catch the heat radiated by the body and help to see in the dark. IR is used in many fields like security etc. http://axtontech.sosblogs.com/The-first-blog-b1/Infrared-Security-Cameras-Effective-and-Versatile-For-Use-b1-p2.htm
