• UDB-IoT: Compact $49 USB-C powered version for low-power IoT devices

This review focuses primarily on the base UDB model, with comparisons to help you choose the right Device Bridge for your needs.

Key Features of the Base UDB

• Wireless Power Delivery: Provides up to 15W of PoE power through a single Gigabit Ethernet port. This is sufficient for 2K HD cameras like the G5 Bullet (4MP) or G5 Flex, which consume approximately 4-5W each. Also powers UniFi Talk phones efficiently. Note: The 15W budget will not power the newer G6 Pro series, PTZ cameras, WiFi 7 access points, or other PoE+ devices requiring more than 15W.

• WiFi 5 Connectivity: Operating on the 5 GHz band with 802.11ac Wave 2 (WiFi 5), the base UDB achieves speeds up to 867 Mbps. While this is a legacy standard in 2026 (two generations behind WiFi 7), it remains adequate for 2K HD camera streams from G5-series cameras and VoIP traffic. For 4K streams from G6 Pro cameras, consider the UDB-Switch with WiFi 7.

• UniFi WiFi Auto-Link: The "magic" feature that makes setup effortless. The UDB automatically detects and links to nearby UniFi access points without manual configuration. Adoption takes less than 60 seconds via the UniFi Network App.

• Integrated Antenna: Built-in antenna provides compact installation without external components.

• Broad Compatibility: Works with UniFi PoE devices including UniFi Protect cameras, UniFi Talk phones, and 802.3af-compatible IoT devices.

The UDB integrates seamlessly with your existing UniFi network and is managed through the UniFi Network application like any other UniFi device.

Why Choose the UniFi Device Bridge?

The UniFi Device Bridge offers several compelling benefits that make it a valuable addition to both home and business networks.

Convenient Wireless PoE

The UDB's most significant advantage is its ability to deliver PoE wirelessly. This eliminates the need to run Ethernet cables to every PoE device, offering greater flexibility in device placement. You can install PoE devices anywhere with a standard AC power outlet—ceilings, walls, detached garages, or temporary locations.

Cost-Effective Solution

Running Ethernet cables can be expensive, especially for long distances or in challenging environments. At $99-$109 for the base model, the UDB is often more cost-effective than hiring an electrician to run conduit or paying for professional cable installation. The cost savings become even more significant when deploying multiple devices.

Simplified Installation

Installation is straightforward: plug the UDB into a standard AC outlet (100-240V), connect your PoE device via Ethernet, and adopt it into your UniFi network using the UniFi Network application. Thanks to UniFi WiFi Auto-Link, the device automatically discovers and connects to nearby access points without manual SSID configuration.

Enhanced Flexibility

The UDB allows you to place PoE devices exactly where you need them without being restricted by cable runs. This is particularly beneficial for security cameras in locations like detached garages, covered patios, or temporary construction sites where running ethernet is impractical.

Which UDB Model is Right for You?

Choosing the right Device Bridge depends on your specific use case:

Quick Selection Guide:

• Installing a G5 camera in a garage with AC power? → UDB (Base)
• Need to bridge to an outdoor pole-mounted device? → UDB-Pro
• Connecting multiple devices in an office or media center? → UDB-Switch
• Powering low-power sensors or smart locks? → UDB-IoT

Technical Specifications (Base UDB)

Before making a decision, it's important to understand the technical specifications and limitations of the base UDB model.

Key Specifications

Limitations

• 15W PoE power budget: Sufficient for most 1080p cameras (G5 Bullet, G5 Flex) and UniFi Talk phones, but will not power PTZ cameras, 4K cameras with IR illuminators at full power, WiFi 6 or WiFi 7 access points, or PoE+ devices. Always verify your device's power requirements before purchase.

• WiFi 5 is legacy technology: In January 2026, WiFi 5 is two generations behind current WiFi 7 standard. While 867 Mbps is adequate for 2K HD streams from G5-series cameras, consider the UDB-Switch if you need WiFi 7 speeds for 4K cameras (G6 Pro series) or high-bandwidth applications.

• Single device limitation: The base UDB has only one Ethernet port. For multiple devices, consider the UDB-Switch (8 ports).

• Wireless range dependency: Performance depends on signal strength from your nearest UniFi access point. Obstructions, interference, and distance will affect reliability. The UDB requires line-of-sight or near-line-of-sight to the AP for optimal performance.

• AC power outlet required: Unlike the UDB-Pro (which is PoE-powered), the base UDB requires a standard wall outlet. This makes it unsuitable for pole mounts or locations without AC power.
