White Glare on Doorbell Camera

We have had our doorbell Camera for several years now. I beleive it is the first gneration doorbell. I have a bad problem during the daytime that I get a bright white glare in the middle of the camera. I do have two decorative white fences in the yard. That should NOT cause the glare. Cameras now are so sophisicated. The glare is no bright I cannot see anything going on in my front yard. How do I fix this problem.
