Hi Folks!
Yup, that's the ending: "smoke got let out". Good thing was not
literally.
Last night opened the failed Ethernet switch just for fun -- combination
of see what's inside and maybe repair or maybe snag a few parts (I do
some electronics hobbyist stuff.) Did find the problem: two
electrolytic capacitors have a noticeable bulge. Brand is Acon, and
yes, they're on the list of manufacturers who had a manufacturing
problem years ago. "Interestingly" the failed cap's are on the load
side of a small power transformer while the those on the line side look
fine.
So with the patched system the live stream videos from the cameras are
back to normal. Have the heat issue still but that's something
different. The 'external accesses' are perkier -- before an ever-so-
slight sluggishness had crept in. Still seems a little odd the one
system for monitoring the live stream was the only one showing a
problem, and didn't show a problem with packet errors.

Ooops!!

Yeouch. Yeah, failing capacitors cause all manner of weird
glitches.
Couple years ago my old switch failed (it just ceased talking to
anything, and went from unpleasantly warm to HOT) and I had to
replace it. Settled on the TP-Link TL-SG108, 8 port gigabit
switch (at the time about $22), bought from their official eBay
store, cuz it was handy.
In fact I liked the first one so much that I promptly bought two
more (so far!) and left 'em a glowing review. Literally plug in
anything any which way (auto port sensing so doesn't matter if
you use regular or crossover cables, nor which cable goes to the
router), plug in the rather generic wall-wart, and it Just Works.
Metal body, compact, and generates only a tiny fraction as much
heat as the old switch; in fact despite that it's fanless, I have
yet to notice either of the two in everyday use getting warm at
all, even when busy. I gather this is because any port that's not
in use goes into sleep mode. Doesn't use enough power to register
on the UPS.
Can also be daisy-chained, as I did initially before rearranging
what's stuck to the router.

Your attic needs an exhaust fan; that would help a lot.
And bad
caps can do stuff like make stuff sluggish rather than failing
entirely. (Eg. slow or spotty USB access = bad caps on the
southbridge circuit.
And I think I just had one such that's on
its way out sort of randomly scramble a directory when I did a
normal file save... part vanished, part reappeared somewhere else entirely, replacing another directory of the same name, but
without deleting anything... no files to recover... Well, we
won't be trusting THAT system anymore...)
As long as only an 'oops' and not an 'ohhh sheeeet'....!
And part of the function of a electrolytic capacitor is to remove AC ripples and line noise, not create it.
The old one hardly generated any sort of warmth either and AFAIK
didn't heat up after the failure either -- 'course the failure in the power supply could have fried the switch part and so nothing to create heat! (It looked unharmed; doesn't take much to open junctions.)

It can be both. Sort of like the meme, where the baby has a
horrified look on his face, and exclaims "OMG!! That wasn't a
f@rt!!". Or, as they describe it in the hospital...a "Code
Brown". How's that for being original?? <G> And, apparently it
happened in another room (the patient pooped in the bed)...as the
female nurse who was supposed to give me a bath, got tied up in
cleaning up the crap...literally.

Speaking of capacitors, the air conditioner guy had to replace
that in the central air unit here, and add refrigerant...cost me
$245. But, at least it's comfortable in here, compared to what it
is outside.

Some other components need a heat-sink (not sure how that's
spelled) to dispel the excess temperature.

It's not a job it's a doody!
It's only 54 here currently!! Unusually cool for the beginning of
Augus. Will be in the low 80's this afternoon; weatherman said the average for the date is 84.
You spelt it correctly, though doesn't use a hyphen (though two words). There were two heat sinks inside, one on each IC which probably control the data movement.

Probably a lot more than the cost of a replacement keyboard!
Or like the sequence from "Three Men And A Baby"...where the
little girl pooped in her diaper. One man says "She did a doodle.
It's your turn to change her"...and the other guy replies "I'll
give you a thousand bucks if you'll do it". <G>

Well, we are on the downside to winter, and meteorological fall
starts September 1.

You risk burning your hands or a item fire without those.

out for my arrest. <G>

Cheap at twice the price!
Did warm up in the afternoon but not bad: only 81; by evening cooled
to the the mid-70s and opened the windows -- helped was breezy. Next Monday and Tuesday won't do that as the feels-like temperature forecast
to be in the low 100's. ...Anyone from the desert areas is going "so?"
-- here it's humid and the perspiration doesn't evaoporate.
I'm thinking more the device would fail before then.
Pfft! If the Society even find out what I did! A couple/few weeks ago
I had accidentally snapped off one of the folding keyboard legs to the keyboard on this computer (got caught on the mousepad) so swapped out
with another keyboard I had in stock. The keyboard with the broken leg has been kept and used with a Raspberry Pi project.

Got to make the money somehow.

We have a potential for strong thunderstorms Sunday, so I might
be down for a bit.

Or the most expensive device will fail before the device
designed to protect it.

Hmm: "Will clean and diaper, $1,000 each."
They're forecasting strong storms between 3 p.m. and 10 p.m. this afternoon. Right now (~7 a.m.) there's a colourful system along the northern boarder of Iowa and heading north-north-east so it's a
different cluster.
Sort of reminds me of when I blew a UPS when testing a computer I was building: puch the power button, BAM!. Was years ago when the Power switch actually directly switched the power on and off. Found out they had wired the switch wrong, so pushing the switch caused a short (!).

So there's a non-offensive cruelty?

We'll see strong storms late this week and over the weekend.
There are heat advisories and excessive heat warnings for my
area.

Did you have to get a new UPS??

Could be.
