Hi! As the title says.. whats the best setup?
At the moment I have two kinect v.1, but I´m now thinking of upgrading to Kinect2. Since I have to use 2 pc´s if I buy two Kinect2 cameras, I might just buy one camera instead. How will my recordings be if you compare 1 single Kinect2 camera vs. dual kinect1 cameras?

Will I get much better if I buy two kinect2 cameras instead of only one? Any advice would be welcome! Thanks for support!

In general, 2 cameras are better than 1 because of multiple points of view. This significantly reduces the number of tracking errors caused by self-occlusion.
However, if motions you capture do not suffer much from occlusion (no full turns etc), Kinect v2 may give you better accuracy of tracking. Kinect V2 has higher effective resolution of depth data with better precision.
