Ubiquiti UVC-G4-DOME 4MP Compact Dome IP Camera
The Ubiquiti UVC-G4-DOME is a fixed-position surveillance dome engineered for integration into UniFi Protect deployments across retail, office, and light industrial environments. Built on a quad-core ARM Cortex-A53 processor, this camera draws just 5W at maximum load via Power over Ethernet (PoE), eliminating the need for auxiliary power infrastructure and simplifying ceiling or soffit mounting. The 109.2 mm diameter dome and 370 g weight make it practical for retrofit installations where space is constrained. NDAA compliance and CE/FCC/IC certifications confirm suitability for regulated procurement pipelines.
Key Features
- 4MP resolution: Captures sufficient detail for facial recognition and license plate reading in medium-range coverage areas (typically 15–25 feet from lens to subject), balancing image quality against bandwidth and storage costs in multi-camera deployments.
- PoE power architecture (5W maximum): Operates on standard 802.3at PoE+, drawing far less than the 15.4W budget — meaning you can chain 4 or more G4-DOME units on a single PoE switch port or injector without power starvation. Voltage range of 44–57V DC tolerates longer cable runs without voltage regulation issues.
- Dome form factor with hard-coated polycarbonate: Renders the lens less visible to subjects, reduces glint and reflection compared to bullet designs, and provides impact resistance in high-traffic environments — but note that dome domes can trap condensation in very humid spaces; ensure mounting includes adequate airflow.
- IPX4 weatherproof rating: Protects against splashing water and light rain, suitable for covered outdoor installations (porches, canopies, light-rain soffits). However, IPX4 is not rated for direct spray or submersion — skip this model if you need full hose-down resistance (that requires IPX6 or higher).
- Operating range -20 to 40°C (-4 to 104°F): Handles seasonal temperature swings across North America and most of Europe without thermal shutdown. Below -20°C or above 40°C, consult Ubiquiti's environmental derating tables or select a hardened variant.
- Aluminum alloy and stainless steel hardware: Resists corrosion in salt-air or chemically treated indoor spaces (parking structures, pool areas), extending service life compared to plastic-bodied alternatives.
- Gigabit Ethernet (1000 Base-T) via single RJ45 port: Integrates into standard IP networks without proprietary cabling; supports inline PoE delivery and encrypted UniFi Protect communication on a single cable run.
- UniFi Protect integration: Analytics and event correlation are handled by the UniFi Protect Web GUI — not on the camera itself. This means compute-intensive tasks (person detection, zone-based alerts) run on your Protect controller or NVR, not locally, keeping the G4-DOME firmware lightweight and update cycles rapid.
When This Is the Right Choice
Deploy the UVC-G4-DOME where you need fixed, full-time surveillance in a compact form factor without pan-tilt-zoom complexity. The low power footprint and tight dome envelope make it ideal for ceiling-mounted office lobbies, retail stockrooms, warehouse receiving areas, and covered loading docks. If your UniFi Protect infrastructure is already in place, the G4-DOME integrates immediately without additional licensing or software provisioning.
When to Choose a Different Model
If your site requires motorized focus, pan-tilt-zoom, or extended outdoor weathering beyond IPX4, evaluate the UniFi Protect turret or bullet form factors in the same product family. For forensic-grade low-light performance or specialized thermal imaging, consult higher-tier Ubiquiti surveillance models. If your NVR or VMS is not UniFi Protect, confirm ONVIF Profile S compatibility before proceeding.
Network and System Integration
The UVC-G4-DOME communicates via standard Gigabit Ethernet with PoE voltage injection (44–57V DC). It operates within the UniFi Protect ecosystem, supporting role-based access control, encrypted event streams, and centralized multi-camera alerting through the Protect controller. If you are deploying alongside IP cameras from other manufacturers, confirm ONVIF support on your recording platform; the G4-DOME adheres to ONVIF standards, enabling broad VMS compatibility.
Durability and Environmental Considerations
IPX4 splash resistance and UV-hardened polycarbonate dome withstand light precipitation and sun exposure, but prolonged direct rain or hose-down will exceed the rating. Aluminum construction with stainless steel fasteners resists oxidation in humid or salt-air environments. The -20 to 40°C operating range accommodates most North American and European seasonal conditions; confirm thermal performance limits if deploying in extreme climates. For PoE switch planning, the 5W draw ensures minimal power-budget stress, even across 30–50 unit deployments.
Power and Cabling
Standard 802.3at PoE+ injectors or switch ports deliver 44–57V DC via the RJ45 connector. The 5W maximum consumption leaves substantial headroom on any modern PoE switch, reducing the risk of cascading power failure during demand spikes. Cable run lengths up to 100 meters (330 feet) are supported; voltage drop is minimal within PoE tolerances, and the camera will negotiate downward if input falls below 44V. No auxiliary power supply, UPS, or separate control wiring is required.
Mounting and Installation
The compact 109.2 mm dome and 370 g weight enable straightforward ceiling mounting with standard drywall anchors or structural clips — no reinforcement beams needed. Recessed and flush-mount options are available via Ubiquiti mounting kits (sold separately). Once powered and discovered on your UniFi network, the camera appears in Protect automatically; no manual IP assignment is typically needed if DHCP is enabled.
Frequently Asked Questions
Q: Is the UVC-G4-DOME NDAA Section 889 compliant?
A: Yes. Ubiquiti has confirmed NDAA compliance for the G4-DOME, making it eligible for federal and state procurement contracts. Consult your purchasing department's current Ubiquiti approved-vendor list for confirmation on your contract vehicle.
Q: What field of view does the UVC-G4-DOME provide?
A: Specific lens and field-of-view specifications were not provided by Ubiquiti in the available technical documentation. Contact Ubiquiti's pre-sales engineering team directly for detailed optical performance data and coverage diagrams for your deployment area.
Q: Can I use the UVC-G4-DOME outdoors year-round?
A: The IPX4 rating and -20 to 40°C operating range suit covered outdoor installations (soffit-mounted, canopy-protected areas). For exposed, direct-rain environments, the rating does not cover extended spray or standing water. Confirm your site's actual weather exposure with on-site assessment before ordering.
Q: Does the UVC-G4-DOME support on-camera analytics like person detection or line-crossing?
A: Advanced analytics run on the UniFi Protect controller or NVR, not on the camera itself. This reduces local processing load and enables rapid software updates to analytics algorithms without camera firmware patches. Your Protect ecosystem must be running current software to enable these features.
Q: What is the warranty on the UVC-G4-DOME?
A: Warranty terms were not specified in the available product documentation. Contact Ubiquiti or your specialty distributor for current warranty coverage and support options.
Q: Can I mix the UVC-G4-DOME with other camera brands in the same Protect system?
A: UniFi Protect is a closed ecosystem optimized for Ubiquiti cameras. The G4-DOME will not integrate natively with third-party cameras in Protect. If multi-vendor surveillance is required, consider deploying the G4-DOME in a separate ONVIF-compliant VMS alongside other brands.

The Ubiquiti UVC-G4-DOME (often searched as UVC G4 DOME) is a no-nonsense fixed dome for compact, low-power surveillance. The 5W power draw is the real advantage here — it means you can deploy dozens of these units on modest PoE infrastructure without hitting switch limits. The quad-core ARM processor handles local edge tasks, but don't expect on-camera AI; Ubiquiti pushes that to the Protect controller. For a warehouse receiving area or office lobby where you need constant coverage and UniFi Protect is already your platform, this is a straightforward win.
Technical Highlights:
- 5W maximum PoE draw: Far below the 15.4W 802.3at budget, allowing you to oversubscribe PoE switch ports with 4+ cameras without triggering power faults. Standard 44–57V DC input tolerates longer runs with minimal voltage drop.
- 4MP sensor resolution: Adequate for medium-range facial and object identification (15–25 feet), balancing storage costs against detail capture in retail and logistics environments. Not suitable for ALPR or long-range forensics.
- IPX4 weatherproof, -20 to 40°C operating: Handles covered outdoor and seasonal temperature swings across North America, but does not survive direct hose-down or extended freezing exposure without derating.
- Dome form factor: Less visible to occupants and more resistant to glint than bullet designs, but condensation pooling can occur in very humid spaces — ensure mounting location has airflow.
Deployment Considerations:
- Field of view and minimum illumination specs were not disclosed in Ubiquiti's public documentation — you'll need to request a full datasheet or coverage diagram from pre-sales before committing to focal length and subject distance requirements.
- Analytics are not baked into the camera; person detection and zone-based alerts require a UniFi Protect controller running current software. If your Protect deployment is underfunded or outdated, analytics won't work.
- The G4-DOME is locked into the UniFi Protect ecosystem — no multi-vendor mixing in a single system. If you need ONVIF interoperability, deploy it in a separate VMS alongside other brands.
Position the UVC-G4-DOME as your goto fixed dome for warehouses, retail stockrooms, and office environments where UniFi Protect is your standard and power efficiency matters. Skip it if you need PTZ, forensic-grade low-light capture, or mixed-vendor VMS integration.
