These are the 3 different types of USB cameras that you can use with Dragonfly. Each has a different connection method.
Important info about the camera
- Using Dragonfly with a wrong camera index(es) can lead to a crash of the Dragonfly App. When this happens Dragonfly needs to be launched again and the index(es) must be adjusted with the correct value(s).
- When the Dragonfly App is installed on Ubuntu inside WSL it is NOT possible to directly access the USB cameras connected to the Windows machine using the camera index provided by Windows. Anyway your USB cameras can be accessed following the instructions inside this page.
