Dahua doobell: which integration to choose among those 3?

Hi,
I’m would like to buy a doorbell and integrate it with HA (guest QR code and keypad), and I’m considering the Dahua VTO doorbell (with camera and/o with camera&keypad)

Surprising, I found two/three different integration:

Does exist a “best solution” among all of them ?

Are there any killer feature that one integration is offering that others are not ?

For controlling the guest acces (with a QR code or with the VTO keypad) which one is better ?

Thanks in advance ,

Giuliano
