If the power supplies have isolated outputs, you should be able to
"stack" them in series to get more volts (as in the case you're looking
at, two 24V in series will get you 48V).
Parallel hookup CAN get you more amps, but the power supplies can buck
each other if they are not designed for it. You need to take that into
account.

That actually works? Does that apply in parallel as well if I have the
voltage I need but not the amperage? I just assumed multiple power
supplies connected together would be like crossing streams and call up
some demonic stay puff marsh mellow crickets or something

Most professional security cameras are either 24v AC or powered
off a .AF PoE switch with a built-in PSU so no external 48v. Your
local electronics supply would be the best chance.

I meant off sources, local type joints that would have it in a
pinch, like plumbing shops carry our masts in stock, but
theyre called water pipe and come in 21 foot lengths. You have
to get them cut, and the cuts not galvanized,, but its
literally the same pipe (thanks sitepro for forgetting your
nail polish wipe)
I really figured the security joint would have it, with
multicam ip cams and all.

I needed one of these in a pinch today called local
electricians and a security outfit, im betting the
security joint has them and doesnt realize it.
Any other ideas on where to look in a pinch?
