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?

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.
