I’m new to Blue Iris and just set up the system with 7 cameras (5x 1.3mp, 1x 2MP and 1x 4MP 5442T-ZE). All cameras are setup with the following settings:
In BI, direct-to-disk recording and hardware acceleration (Intel+VPP) is enabled. It’s a i5-12400 machine with 16GB of ram. Database is on SSD and recordings to a WD Purple Pro disk. All cameras are set to record continuously.
When I view the live streams I haven’t noticed any stutters, but most of the alert videos have stutters (sometimes several seconds long).
I’m specifically looking at the 5442 cam that triggers based on the Dahua smart detection. However, when I started looking into the issue I have also noticed stutters in the recordings of other cameras at the same time as the alert was triggered at the 5442 cam. I have also noticed random stutters in the recordings at other times, but I have not been able to find a pattern yet. I have also monitored CPU, RAM and HDD usage but most of the time CPU load is 5% or less and never more than 25%. RAM hovers around 50% and HDD load is also just a few %. I don’t see any packet loss or ping spikes either.
Does anyone have any idea what might be the issue here?
