PoE Smart Chime is the version I prefer whenever a site already has structured cabling or a UniFi switch nearby.

The PoE Smart Chime pairs with the G4 Doorbell Pro to provide an audible alert inside the building when someone presses the doorbell. It connects over your network via PoE rather than to the traditional two-wire doorbell circuit, which means it mounts anywhere a Cat6 cable reaches.
The chime tone and volume are configurable through UniFi Protect, and it can also announce Protect events beyond just doorbell presses.
The G4 Doorbell Pro sends alerts to the UniFi Protect app on your phone, but in a larger building or when you're away from your device, a physical audible chime still has value. The PoE Smart Chime adds that physical alert without relying on battery life or WiFi.
Wireless chimes, including the kind bundled with consumer doorbells, depend on an RF signal that can be blocked by construction materials or interfered with by other devices. A chime that runs over your wired network and PoE doesn't have that problem.
Chime response from doorbell press to audible alert is typically under two seconds. Volume is sufficient for an average-sized residential space. In a large open commercial space you'd want multiple units.
PoE-powered over your wired network makes this one of the simpler devices in the UniFi ecosystem. No battery, no WiFi, no sync issues. It either has a network connection or it doesn't.
Pairing can occasionally need to be re-established after a Protect firmware update. Check functionality after updates rather than assuming it carried through.
Adopt the chime in UniFi Protect, link it to the doorbell under the doorbell settings, mount it near a Cat6 drop. The whole process takes about ten minutes once the cable is in place.
For a professional install, adding a wired chime to a wired doorbell system is the right approach. The PoE Smart Chime completes the G4 Doorbell Pro installation in a way that feels finished.
If your building already has existing wired doorbell chimes on the original two-wire circuit, the G4 Doorbell Pro can be configured to trigger those instead. The PoE Smart Chime is for cases where that existing wiring doesn't exist or doesn't reach the right location.
