Eufy 2k wired doorbell voltage

[tco4]

I have just bought the Eufy 2k wired doorbell camera.

The website says the doorbell requires:
16-24v, 30VA

The back of the actual doorbell states:
16-24v ~ 0.3A.

I have an old style intercom currently connected to front door. It’s transformer states:
+12V )
) 3W

• 8V )

~13V -/~ 13VA

Does anyone know would this current transformer actually work? (Even though it below recommendation)?

Thanks.
