Anyone have any tips for improving image quality on this doorbell camera? Can't tell if my lens is going bad from a couple of years of sun exposure or what, but the picture is grainy both during the day and at night (though it was never really a great picture to begin with). At night, in particular, it's basically unusable. Could be because of IR reflections and ambient lighting (those are Christmas lights on house across the street) which isn't helping. I have both mounts in play to point it right and downwards, and it might benefit from some additional downward direction as well. Thanks.
