Before purchase, like to have following questions to be answered, related to Wired Doorbell (Db)

[pdp0617]

1) How does the Db Camera activate a chime?

2) I cant seem to find a chime on the web site to go with the Doorbell Camera. Would be very nice to have one that plugged into an existing 110 outlet. Is there a brand & model thats recommended?

3) Is there a transformer brand & model that can be recommended?

The doorbell connected to a hardwired doorbell chime with the doorbell connection unit included with the WIRED version of the doorbell.  

You can check transformer compatibility here

Question is, does your home already have a hardwired doorbell installed ?  If not, it may be a bit difficult to retrofit one, and you may be best to just grab a Google home speaker to act as your bell via wifi.
