New Hope and Ivyland Railroad: mini-cam under train, comment if it's too tall

Testing my new tri-pod for my mini-cam, I am bringing my mini-cam to put under 611 soon and I don't want the camera to knock over when 611 goes over it. So, I have this tri-pod that makes it quite stable, but will it be too tall and get hit by 611? Well, that's what this test was for, it did not get it by 2198 at the NH&I RR but it was close, so, do you guys think it was too close or it should be fine?
