UPS backup battery system - DIY build

Mornin’ folks
Anyone ever build their own? If so, where did you buy the “brain”?
I’ve watched a few videos, and can only find where they add batteries to an existing system or build a backup power station that doesn’t have the automated switch feature for power outages.
Looking to build a system to run PoE camera system during our intermittent power failures/hurricanes. Haven’t ruled out buying and simply adding batteries to it, but ideally, I’m just looking for the brain.
TIA

Need more info.
What is the power draw of your cameras system?
How long do you want to keep it up?
But if you want to keep it up longer than maybe an hr, you will end up with a wall of batteries.

Theoretical it should be easy. You'll need a 120 volt AC to 12v DC trickle charger. Connect that to a 12v battery bank. Then a simple 12v to 120v inverter (with enough watts to run your cams.)
The real issue becomes power draw and having enough amp hours from the battery banks.

We built our own. Went with Newmar AC-UPS-48-2000. Probably a bit overkill for what you're doing but it's definitely robust.

That’s what I’m planning on doing, or something similar. Where I’m getting stuck is automatic switch from charging to use when power goes out.
Some videos online showed bigger batteries powered their camera system for a decent number of hours.

If you have 2 or 3 cameras just get an APC unit. But again, we need more info to help you.
How big is your system?

Easy. All you need is a simple relay module. Wire it so when the power goes out it switches the voltage from 120v constant line power to the power from the inverter battery.
HiLetgo 12V 1 Channel Relay Module with Optocoupler Isolation Support High or Low Level Trigger
Caution: You'll be dealing with mains voltage (120v AC) thru the relay so be very careful when handling it.
