Hello,

Thank you for your questions.
To control the doorbell from multiple phones, you can simply log into the same Tapo account on the other phone(s). This will give all devices linked to that account access to control and view the doorbell.

Or you can share the doorbell to other account, please refer to this: Share Tapo and Kasa Devices with Family or Multiple Users (Device Sharing 1.0)

Regarding adjusting the detection distance: The doorbell itself does not have a physical detection range adjustment. However, you can effectively shorten its responsiveness by lowering the “Wake-up Sensitivity” (or Motion Detection Sensitivity) in the doorbell’s settings within the Tapo app. Reducing this sensitivity means it will be less likely to trigger for movements that are farther away or less significant. For detailed steps, you can refer to our official FAQ here: What is the Wake-up Sensitivity of my battery camera/doorbell?
