The issue comes up on BlueIris. It seems like when it goes into night or day mode it will get all garbled on BI. Within BI if I select restart camera it restores the image.
I only just received these cameras and have not set anything up, just testing them on the bench right now. All the settings are on default at the moment.
In that case it is probably the codec being used in the camera. Change to H264H and general codec and FPS at 15 and iframes at 15.
I am using it fine in BI.
