Ubiquiti UVC-G5-DOME-ULTRA Compact 4K Dome IP Camera
Overview
The Ubiquiti UVC-G5-DOME-ULTRA is a fixed-lens compact dome camera built for ceiling-mount surveillance in retail, office, and entry-point environments. At just 63.6 mm diameter and 68.2 mm height, it integrates into recessed ceiling infrastructure where larger turret or bullet housings won't fit. The UVC-G5-DOME-ULTRA (often searched as UVC G5 DOME ULTRA) draws power and signal over a single PoE connection — no auxiliary wiring required — and operates within the UniFi Protect ecosystem, eliminating the need for standalone licensing or external management consoles.
Key Features
- 4K Resolution (3840 × 2160): Delivers enough pixel density to read faces and detail at typical ceiling-mount distances (8–15 feet). Higher resolution also enables digital zoom in post-event review without quality loss.
- Fixed Focal-Length Lens: A single, non-adjustable lens means no motorized focus drift, no servo power draw, and predictable coverage geometry during design. Trade-off: you must confirm sight lines during pre-deployment planning to avoid missed zones.
- Night Vision (IR): Integrated infrared illumination enables monitoring when ambient light drops. Exact IR range and wavelength should be confirmed with your distributor to validate coverage in target monitoring areas.
- Dual-Core Arm Cortex-A7 Processor: On-camera encoding handles H.264 and H.265 codec selection in real time, reducing bitrate when network bandwidth tightens and maintaining frame rate during motion spikes. This edge processing means your NVR does less work per stream.
- H.264 and H.265 Codec Support: H.265 compression cuts storage requirements roughly 40–50% versus H.264 on identical bitrate targets — a meaningful cost factor when recording 24/7 across 10+ cameras. Codec selection adapts automatically based on controller policy and network conditions.
- Standard PoE Power (4.2W Max): Ultra-low power draw means you can run long Cat5e runs without voltage sag, and a single PoE switch port can power multiple units via managed distribution. No 12VDC brick or high-amperage wiring needed.
- NDAA Compliance: Satisfies Section 889 federal procurement rules — a requirement for government and critical-infrastructure projects. CE, FCC, and IC markings confirm electromagnetic compatibility for North American and European deployments.
- UniFi Network Integration: Pairs directly with UniFi Dream Machines, UniFi Network servers, or UniFi Protect hubs. REST API support enables custom automation and rules-based alerting without third-party middleware.
- Corrosion-Resistant Aluminum and Stainless Steel: Housing materials withstand humid indoor environments. Operating range of −20 to 40°C covers unheated warehouses and climate-controlled offices without performance derating.
- Compact Ceiling Mount Footprint: At 175 g (6.2 oz), installation requires no structural reinforcement — standard drywall anchors or plenum-rated ceiling frames suffice. Quick-start wiring simplifies first-time deployment.
Integration and Compatibility
The UVC-G5-DOME-ULTRA ships with mounting hardware, an Ethernet cable, and quick-start documentation. Integration into a UniFi Protect NVR or cloud-managed recording setup requires only network discovery and controller pairing — no manual IP assignment or certificate installation. Third-party IP camera platforms may integrate via ONVIF standards, though deep UniFi features (analytics, codec negotiation, power scheduling) function only within the UniFi Protect environment.
When to Choose This Model
Ideal for recessed or surface-mounted ceiling applications where space constraints, aesthetic integration, or standard mounting infrastructure favor a small dome. If your project has sufficient PoE switch capacity and fixed-angle coverage meets sight-line requirements, the UVC-G5-DOME-ULTRA delivers 4K detail at minimal operational cost.
When to Consider an Alternative
If deployment requires pan-tilt-zoom capability, wide dynamic range (WDR) processing for high-contrast scenes, or ultra-low-light performance beyond entry-level specs, evaluate higher-tier variants in the Ubiquiti lineup. Similarly, outdoor installations or extreme temperature environments (below −20°C or above 40°C) demand weatherproofed models with elevated IP ratings. For guidance on camera selection and site survey methodology, consult your systems integrator.
Installation and Mounting
Mount height, viewing angle, and lens coverage area must be validated during design. A 63.6 mm dome body fits standard 4-inch recessed ceiling rough-ins and integrates into drop-tile grids without modification. Verify obstruction-free sight lines to doors, cash registers, loading bays, or other critical zones before final placement.
Storage and Bandwidth Planning
At 4K resolution and H.265 encoding, a single camera generates roughly 1–2 Mbps bitrate at typical quality settings. Over 30 days of continuous recording, expect 3.6–7.2 TB of storage per camera, depending on codec choice and retention policy. NVR sizing and storage planning guides can help scale across your full deployment footprint.
Power and Network Infrastructure
Verify your PoE switch has available 802.3af capacity. At 4.2W per camera, a 24-port switch (95W total budget) can power 20+ UVC-G5-DOME-ULTRA units simultaneously. Use Cat5e or Cat6 cabling rated for your environment (plenum or riser in vertical runs). If runs exceed 100 meters, test voltage drop at the camera end — standard PoE keeps output within safe margins.
Frequently Asked Questions
Q: Is the UVC-G5-DOME-ULTRA NDAA Section 889 compliant?
A: Yes. The UVC-G5-DOME-ULTRA carries NDAA compliance certification, satisfying federal procurement requirements for government and critical-infrastructure projects.
Q: What codec options are available on the UVC-G5-DOME-ULTRA?
A: The camera supports both H.264 and H.265. H.265 reduces storage by 40–50% compared to H.264 at equivalent quality, and the controller selects the codec dynamically based on network conditions and policy.
Q: Can I power the UVC-G5-DOME-ULTRA with standard 802.3af PoE?
A: Yes. At 4.2W max power draw, the UVC-G5-DOME-ULTRA operates on standard PoE (802.3af), eliminating the need for a separate power supply or high-amperage wiring.
Q: What is the field of view and focal length of the fixed lens?
A: The UVC-G5-DOME-ULTRA uses a fixed-focal-length lens optimized for standard interior coverage. Exact horizontal and vertical field-of-view angles and focal length should be confirmed with your distributor during pre-deployment planning to validate sight-line requirements.

The UVC-G5-DOME-ULTRA is a straightforward tool for recessed ceiling deployments where real estate and PoE simplicity matter. At 4.2W draw and fixed optics, you eliminate the gotchas that complicate turret rollouts — no motorized focus creep, no servo power surges spiking your switch, no 12VDC infrastructure to run separately. The 4K sensor and H.265 codec make the resolution-versus-storage tradeoff workable for 24/7 recording in moderate-scale retail and office environments.
Technical Highlights:
- H.265 Codec with On-Camera Processing: Cuts storage 40–50% relative to H.264 at the same bitrate. Dual-core ARM processor handles real-time encoding and bitrate adaptation — your NVR or recorder just receives the stream and writes to disk.
- 4.2W PoE Power Budget: Standard 802.3af injection means you run standard Cat5e, no high-amperage drops. At that wattage, a 95W PoE switch can power 20+ units without negotiation. Voltage drop over 100m cable runs stays within safe limits if you use decent cabling.
- NDAA Compliance with CE/FCC/IC Marks: No surprise certifications or missing regulatory paperwork. Clears federal procurement gates and ships to North American and European sites without import friction.
- Aluminum Dome + Stainless Steel Fittings: Corrosion resistance in humid indoor spaces is solid. Operating range −20 to +40°C covers unheated warehouses and climate zones without performance derating.
Deployment Considerations:
- Fixed Lens Means No Zoom or Focus Adjustment: You must confirm sight lines and coverage angle during site survey. No motorized lens flexibility post-install — get the mounting height and angle right the first time, or you're re-drilling.
- UniFi Ecosystem Dependency: This is a UniFi Protect native. ONVIF passthrough means third-party VMS can see the stream, but codec selection, analytics scheduling, and power management live inside UniFi only. If your shop is Milestone, Genetec, or Hikvision-native, this camera becomes a silo.
- IR Spec Clarity: The datasheet calls out night-vision support, but exact IR range (meters), wavelength, and illumination pattern aren't nailed in the evidence. Confirm with your supplier before committing to lighting-absent zones.
Deploy the UVC-G5-DOME-ULTRA for retail ceiling grids, small-office entry-point monitoring, or warehouse overhead coverage where PoE simplicity and fixed-angle geometry fit the site. It's not a versatile tool — it's a purpose-built fit for UniFi shops with ceiling-mount budgets and no need for pan-tilt-zoom flexibility.
