Hi folks,
Short story: the expedient expansion plan I'm considering means putting a UPS and a POE switch into my garage, in Indiana so temp range in there goes from about -10 (garage open on cold winter day) to probably 120 at its hottest. Will the UPS and switch be seriously compromised by temperature?
Longer story:
I'm sliding down the slippery IPCAM slope. I've had 9 cameras running great for nearly two years. But it's time to freshen the mix by adding a couple new ones.
Currently, all nine are wired home-run to the computer/POE switch (and one single port injector) which lives in a corner of the basement where there's a dedicated circuit with a UPS. If the power goes out, I've got about an hour of recording before things shut off. Of my 9 cameras, 5 are mounted on exterior walls of the garage; it juts out a bit from the house so it has east, west, and north facing angles which point in the directions I care the most about. I wired them one at a time over a three month period, and toward the end I wondered why I didn't just run one wire to the garage, and get a POE switch in the garage, instead of dragging all those cables down into my basement.
The new cameras are mostly going to be wired through the garage, one way or another, so rather than adding more home runs, I figured to tap into one of the existing cables, pop a POE switch on it, and run the new cameras (and the camera I stole the line from) out of that switch. There would be a UPS to drive the POE switch. But, I worry about the UPS batteries or circuitry failing due to hot garage syndrome, and somewhat the switch too. It gets hot and cold in there.
Am I making a mountain out of a molehill here? I mean, car batteries are lead acid too, and they survive in the garage... but then again maybe UPS batteries aren't spec'ed for the temp swings. Sure, I could always forsake the UPS, and have a few blind spots when the power goes out, occasionally, but that's not how my scientist/engineer mindset works.
Would appreciate your thoughts on this. The job is a LOT easier if I can wire 'em up from a splitter in the garage....
