FAQ
What is the input voltage requirement for this power supply?
This Ubiquiti power supply requires a 120V AC input, which is the standard household voltage in North America. It is designed to plug directly into typical wall outlets without requiring additional transformers or voltage converters.
What output does it deliver to the doorbell?
It delivers 20V AC output at a maximum current of 700 mA. This provides the precise voltage and sufficient current needed to power the UniFi UVC-G4 Doorbell's camera, processor, network module, and audio components continuously.
Is this power supply compatible with other Ubiquiti devices?
No, it is specifically engineered for the Ubiquiti UniFi UVC-G4 Doorbell. Using it with other devices may result in incorrect voltage delivery, potential damage, or voided warranties. Always use power adapters matched to the manufacturer's specifications for each device.
Can I use this outdoors or in wet locations?
The polycarbonate housing offers durability, but it is not rated for direct exposure to water or extreme outdoor conditions. Install it in a protected location such as indoors, in a weatherproof enclosure, or under eaves to prevent moisture ingress and ensure safe operation.
What is the advantage of a dedicated power supply over existing doorbell wiring?
Dedicated power supplies like this one provide stable, consistent voltage and current that older doorbell transformers often cannot sustain. This prevents issues like voltage drops, intermittent operation, or reboot cycles that can compromise video doorbell performance and security monitoring reliability.
How do I install this power supply with my UniFi G4 Doorbell?
Connect the power supply to a standard 120V AC outlet, then run the low-voltage cable to the doorbell's power terminals. Ensure all connections are secure and protected from physical damage. Refer to the Ubiquiti installation guide for detailed wiring diagrams and safety instructions specific to your setup.
