The Piranha XL Camera

Camera Information Category

Camera information can be retrieved via a controlling application. Parameters such as camera

model, firmware version, etc. are read to uniquely identify the connected Piranha XL camera. These

features are typically read-only.

The Camera Information Category groups information specific to the individual camera. In this

category the number of features shown is identical whether the view is Beginner, Expert, or Guru.
