How to configure HTC Vive trackers to tracks DSLR camera

Hello everybody,
I intend to create mixed reality videos, and the idea to track my camera into unreal by using an HTC Vive tracker mounted on top of it seems exciting.
I have some specific questions:
1-The tracker alone is sufficient or a complete htc vive system is necessary?
2-With an htc vive system since it has 2 controllers, can’t we just use one controller instead of the vive tracker?
3-Is the system natively supported or requires particular programmation skills?
I believe i have a basic 3d knowledge with basic capacity of editing / scripting.
I wish to thank you very much in advance for the eventual answers, i browsed the forum but i could not figure out well the whole process.
