Re: [Motion-user] Recording Skip

[Barry M. <bar...@gm...>]

Hi Folks!

I think this is the much-awaited conclusion to my inquiry about 
skipping.recording glitches,


Original:    2x Raspberry Pi 4, via built-in 5G, with one USB camera 
each; record to a NAS.  Using Motion Version 4.5.1. Powered by official 
wall warts plugged in to a small UPS.

No problems detected with the WiFi signal, recording media,


Changes, updates.  Raspberry Pi's now using a PoE HAT.  I also 
physically switched the PI's but ":should be' the same as the 
originals.  Also switched the recorded file site from a hard drive on 
the NAS to a Raspberry Pi 5 with NVMe storage.  Switching to solid state 
storage didn't seem to make any difference.  Switching to wired data 
transfer (PoE) maybe made a little difference -- slightly better: 
glitches maybe half as long.

The last change I made was to slightly overclock one of the RPi4's -- 
the one with the definite glitches.

     /boot/firmware/config.txt
     #1.8 GHz to 1.9 GHz
     arm_freq=1900
     over_voltage_delta=25000

The 'over voltage delta' is the new/preferred command over the previous 
overvoltage (with Bookworm, anyway).

I might overclock the other Pi later.


So the good news is the glitching seems to be all but eliminated: only 
getting a few short-duration glitches, approximately a half-second.  
Immensely improved over the two- to sometimes ten second skips previously.

Thanks to all providing hints!
