Is it possible to split the door ring bell box to a USB outlet?

Hi

I'm trying to set up a security camera at the front door.
Unfortunately, there's no outlet nearby except the door bell box.

I'm thinking to split the power wire to door bell, one cable connects to door bell, another one connects to USB outlet.

The USB outlet will be modified from the regular USB adapter from cell phone.

Please let me know your thoughts.

Thanks in advance,
Jeff

Of course you can if you know how to solder. Better make sure your door bell is on the voltage you want (5V ideally) with appropriate current rating.
If the women don't find you handsome, they should at least find you handy.

I'm guessing you can only run one or the other.
When the door bell is pushed, it's likely that the 24V drops close to zero, you'll actually have to measure how many volts you have
What you don't want to happen is when the door bell is pushed, the volts drop to zero and the USB outlet (and camera) goes off line

I think the wire is not 110 because it looks thinner than the other.
Just wondering if it's 24v, what would be the best way to make it able to power the USB camera?

I'm thinking the bell might have the option to be powered by battery, will be checking tomorrow.

Standard door bells usually have a 24V AC current. USB is DC current. Completely not compatible.

If the doorbell is 24v then with this you'll need a usb car charger since they run on 12v and this outputs 12v https://www.ebay.ca/itm/24V-AC-step-dow ... SwuxFYvixv
With this one you get variable output so once you adjust it to 5v you can connect the +/- wires in a usb cable straight to the camera https://www.ebay.ca/itm/3-3V-5V-6V-9V-1 ... SwUpFcAPOc

I'd opt for the first one since it just looks more reliable being a bigass heatsink.

just fish the camera wire in your walls and into your basement instead of trying to macguyver it into your door bell circuit. fishing wires is 100% the way to go, do it right the first time
Say NO to the WAR!
PEACE is the answer!
