500 meters is what? Around 1500'? Close to it anyway, that would be a speck in the sky if you could see it all & you'd have to be completely reliant on the camera, wouldn't you? I'm just curious?
Ironically, I have noticed over the past year or two that at & around my residence the low alt. aircraft traffic has increased & this is in an area with antenna which they are right at the limits of minimum air separation. Can't say what the call for the increase in aircraft traffic is from? At this point it wouldn't surprise me if the FAA is pushing them down on approach & departure. When I used to fly without any aircraft audible in the vicinity, now I have at least one within audible range & more often multiple.
