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!
Barry
