Hey @Quico. Happy to answer any questions you have! You can learn more about what’s in the box for the Ring Video Doorbell 3 here. You can download the manual here. The product does not come with a Chime included in it, you will need to buy this separately. You can buy any many Chimes or Chime Pros as you would like to extend the Doorbell’s Ring and Motion alerts, as well as help with internet connectivity if you get the Chime Pro.
The Ring Video Doorbell 3 should be able to connect to Alexa as well and show up on your Alexa Show 8, as well as the 5. Once you have downloaded the Ring skill, the Doorbell should show up as a new device once added to the Ring app. Lastly, the Ring Video Doorbell 3 does have some differences in comparison to the Pro. The Ring Video Doorbell Pro does have more advanced motion detection, as it uses motion detection that is pixel based from what the camera sees, while the Doorbell 3 used PIR motion detection. Both devices have a pre-roll that is running to help capture motion as it’s happening, but the Doorbell 3 will have those few seconds of pre-roll in black and white while the Doorbell Pro should have it in color. The devices also differ in power sources, as the Pro needs to be hardwired the entire time it is set up, but you never have to worry about charging, while the Doorbell 3 has the removable battery that will have to be charged every so often. Hope this helps!
