I have a few Dahua IP security cameras which seem to be loosing peripheral IR illumination.
I haven't kept any snapshots from first installation.
Maybe related to aging or lower winter temperatures.
Anyone have any experience with loss of camera peripheral illumination?
Here are a few snapshots showing night and day views.
