Use a multimeter to check the voltage of a transformer
1. Disconnect your existing doorbell.
To do this, unmount or unscrew your existing doorbell to expose the wiring or AC
terminals on the back.
2. Set your multimeter to AC (the V with a wavy line on top or next to it).
3. Connect the two probes from the multimeter to the wires from your doorbell.
4. Read the voltage level on your multimeter’s display.
If the voltage level is between 16-24 VAC, you can use the Arlo Video Doorbell
with your current doorbell transformer.
If the voltage level is lower than 16VAC or the transformer is underpowered (less
than 10VA) then consider having the transformer replaced by an electrician or a
professional service provider.
Check the voltage level printed on the doorbell
transformer
A doorbell transformer is a device that steps down your household AC voltage to a
lower voltage suitable for powering an electric doorbell.
The transformer is typically found:
• In the front closet near your existing doorbell
• Near your house’s circuit breaker
• In the basement or attic
• In the garage
• Near your house’s furnace
