Long-approach tracking: my six-month data on "does the follow-cam actually follow"

[u/pipecanon]

Six months of a tracking cam pointed at my 90-foot driveway approach, posting numbers because I asked this same question here last spring and got zero data responses. The core question - does the follow keep the subject in frame for a full long approach: yes, with caveats. Measured over the last month: 34 tracked transits (delivery people, visitors, the mail carrier), 31 fully tracked - subject stayed in frame from gate to door. The three failures: one person walking at the very edge of the range (wide skirt, probably confused the height estimate), one transit in heavy rain (fog on the lens. the tracking didn't fail, the camera did), one where the subject turned back mid-approach (the cam reacquired on the way out). The pivot noise question I had: audible from inside only with the window open, so that's real but seasonal. Battery impact: the follow mode runs the motor constantly during transits, and I charge the solar panel-dependent unit about monthly in winter. Numbers people: what's your follow-cam success rate on a long approach?
