Setup and power requirements

To use your G4 Doorbell, you will need:

• A network video recorder (NVR), such as the UniFi Dream Machine Pro (UDM-Pro), UNVR, or Cloud Key Plus (UCK-G2-PLUS).
• An UniFi Protect Controller hosted on any of the NVRs above. For more detailed setup instructions, see UniFi Protect - Set up the UniFi Protect Controller.
• A 16-24VAC, 20-30VA power line.

Note: In existing installations in Europe, the doorbell chimes may be 230V, which may not function properly with the G4 Doorbell. We recommend confirming your chime and transformer are compatible with 24V AC. For a list of compatible chimes, please visit the G4 Doorbell product page.

While the G4 Doorbell has its own camera, it can also be used with other UniFi Protect cameras.

Install, adopt, and configure the G4 Doorbell

Follow the Quick Start Guide or watch the video below for step-by-step installation instructions.

Note: All wiring must be done prior to installing the G4 Doorbell. The bell itself must be connected in a series circuit including a chime box and a transformer.

You can also power your G4 Doorbell via a standard US electrical outlet using the UniFi G4 Doorbell Power Supply (G4-Doorbell-PS-US, available on the US store only).

To manage your newly installed doorbell, you need to adopt it to your UniFi Protect Controller.

For more information on the adoption process, see UniFi Protect - Adopt and manage devices.

No, the doorbell is powered by either a 16-24VAC, 20VA transformer, or a power supply unit, and uses WiFi for connectivity.

My G4 Doorbell frequently disconnects and reconnects to the Wifi. How can I fix this issue?

There are two main reasons for frequent G4 Doorbell disconnections and reconnections:

• Weak WiFi signal: Check your WiFi connection in the Protect mobile app (in Camera Setting > Connection) or the web browser (in Camera Settings > Overview > Details > Link State). If the score is poor (<50%), try reducing the distance between the doorbell and the WiFi router or access point.
• Incompatible power source of your G4 Doorbell: Please ensure that the transformer powering your doorbell is rated 12-24VAC, 20VA.
