Dear, Natacha Rossi

I can recommend the following

NIKON D850

It comes with software. It's cheap enough for this kind of research.

Hi Pushkin Sergey Viktorovich ,

Thank you very much for your answer, but I'm actually looking for a 3D tracking system with which I could actually reconstruct the trajectories of the bees, and not move the focus point to follow the movement of the subject as the Nikon D850 does.

Dear Natacha

Please check these 2 articles:

Bees are identified in term of three differ- ent behaviors: • fly in the beehive: entrance • fly out the hive: departure • flying by the hive.

I am sorry, This is new for me. Can you give me more clarification about it and uses??

We are using Noldus 3D Tracking system for our wind tunnel. It works great. There is another company in Europe that do the same thing: Loopbio. Them seem to be very knowledgeable too. Unfortunately they do not operate directly in the US, they use contractors.
