I replaced a HikVision camera with a Dahua camera. I am monitoring it through BlueIris(BI) but BI about 25% of the time says it lost the signal to the camera. It automatically comes back after some time. I never had this issue with my HikVision which had a similar resolution and was set to 8kbps as I did with the Dahua. Maybe I got some settings wrong but what could cause this?
