2.5k resolution // live view

[ktara156]

My cameras have two 'streams', 1080p and 2.5k. I use 1080p for live view and image analysis (for alarms). 2.5k for continuous recording. Processor usage around 1-2% usage. When I turn on encoding for 2.5k streams (to get higher resolution live view), the buffer seems to overloaded - The live preview plays back slower than real-time – essentially, one second of video corresponds to about one and a half to two real-time seconds. This means the live preview eventually becomes out of sync. Processor usage is still at the low level 7-10%. What is wrong? What should I check?

I think you should continue to use 1080p for live view and image analysis. Keep 2.5K for Passthrough or Record only recording geometry vibes, avoid continuously turning on live view at this resolution.

Yes, for now I will stay with this solution. But the question is WHY is working poor with 2,5k? In terms of CPU usage there is still big headroom (~90%), also the same in RAM. What I'm missing?

Possibly a drive write bottleneck. Do your continuous recording/motion detection (MOCORD) at 1080P and use it to trigger recording at your 2.5K. Also turn your frame rate down. 10 FPS is good for a security system.

Half of my cams do MODECT at 4MP and they write to a M.2 SSD with no issues. If you tweak your zones for better motion detection you can turn off full time recording. My cams detect a rabbit in the yard and sometimes a bigger moth at night. I also delete events with four or fewer alarmed frames.

Thanks! I'll try to do that. Please tell me, what type of function should I use for 2.5k? I understand that I in 2.5k stream 'link' with 1080p, but in what function? in 1080 I'll stay with MOCORD.

Set the 2.5K cam to MONITOR. In the same cam General/Linked Monitors select the 1080 cam to be the "trigger." When the 108 cam detects motion the 2.5K cam will record.
