For example, this 850VA unit is rated for 460W and has a 12V/7.2Ah battery powering it, which at a constant half load (230W), the UPS is estimated to last Just under 10 minutes.
Recognize that 850VA isn't capacity but power it can provide. So you might think this 1500VA may last longer:

But it won't, since it has the same battery in it (12V/7Ah).
*CORRECTION* According to the specs, it has two of the 12V/7Ah batteries, so it should last twice as long.

Interesting, I've never had an issue with that over the years. Various different Costco's in two different east coast states.
Basic way to figure it out?
1. Add up the various power draws
2. Go to the manufacturer page for the product (https://www.cyberpowers
3. Under the "Runtime" tab, find your power draw and corresponding run time on the graph.
APC product pages are slightly more helpful in that they allow you to directly enter the Watts, and the page displays the expected run time. They also have graphs in the product specs.
HOW to calculate the power draw of the various devices? Kill-A-Watt power meter is handy for that. When you say "A Synology" you're not saying much really. Is it a 2-bay? 4-bay? 8-bay? Disks spinning? Disks stopped?
I can tell you my DS920+ with 4x8TB WD Gold drives draws about 30W at idle according to my APC UPS (BR1500MS), for example.
The modem, router, and cameras should probably have a pretty stable power draw. Just look at what each device consumes, calculate it, add it all up etc.
Looks like this CyberPower UPS has a USB Type B port. So it could conceivably be connected to your DiskStation. You can have the DiskStation shut down when the UPS gets to a certain power level. I have mine set pretty aggressively, to shut down when the UPS hits ~75% power. That way other more important devices (e.g. router, fiber ONT) can continue to be powered for much longer, if the power is going to be out for a while.

15% wouldn't work out of the box
40% would fail in warranty
100% failed after 3 years

Now that I don't work there, I still call in and ask "Hey I saw this online and was wondering if it's in store and on sale" and they always tell me number on hand and prices.
Sounds like your warehouses have power crazy general managers with store specific rules.
