I see a bear. Short stubby tail, legs are too big around for a pig, which would taper down to a much narrower hoof. You can only see one leg in the front as it is walking, and the pad of the front foot is wide. I don't think it's a young bear either, not huge but decent sized.
One big problem with IR cameras when the animal is moving the picture gets blurry and they just don't show the detail; with a flash camera in color it would be obvious.
