Found the patent. The first-listed inventor, Joshua Gaskamp (the guy in the video), has multiple related patent applications, but I believe this is the big one: US Patent #9,237,743.

Per Frank S's comments, it looks like they previously played around with a square or rectangular design before deciding on the circular trap with the spiral trap raising/lowering mechanism.

This thing looks fun to use! I guess you get a notification on your cellphone, then you watch the video footage, waiting for the entire sounder to enter, then you remotely trigger the trap.
