If the camera is in the same place take a measurement in the same location the cat was in, that would tell you. My guess is house cat, they travel incredible distances and the tail looks thin and low to the ground but just a guess.
I would go back to that camera location and let the camera take multiple pictures of you standing at various points where you think that photo of the tail was captured. Then compare this photo with those photos. That would give you some sense of scale so you can get a better idea as to what type of cat you have.
