Ubiquiti UVC-G5-DOME-ULTRA-B 4K Dome Camera
Overview
The Ubiquiti UVC-G5-DOME-ULTRA-B is a compact 4K dome camera purpose-built for indoor and covered outdoor surveillance within Ubiquiti IP cameras ecosystems. This model combines a vandal-resistant dome housing with 4K resolution and PoE power delivery, eliminating the need for separate AC runs at each installation point. The UVC-G5-DOME-ULTRA-B (often searched as UVC G5 DOME ULTRA B) operates exclusively within the UniFi Protect management framework—there is no standalone mode. If your deployment centers on a multi-site UniFi infrastructure with centralized controller management, this camera delivers straightforward integration and consistent firmware rollout across locations.
Key Features
- 4K Resolution (3840 × 2160): Captures fine detail necessary for identity verification and incident reconstruction in standard lighting. Significantly higher pixel density than 1080p or 2MP alternatives, meaning faces and license plates remain legible even when zooming into recorded footage—critical for post-event investigation without requiring pan-tilt-zoom capability.
- Night Vision: Infrared illumination enables surveillance in darkness without requiring external lighting. Check manufacturer specifications for actual IR range and minimum lux thresholds to confirm adequate coverage for your site's nighttime geometry.
- PoE Power (802.3af): Draws power exclusively via standard Ethernet cabling, eliminating dedicated 12VDC or AC supply lines. Reduces installation labor and eliminates power supply single points of failure. Confirm your switch or PoE injector has sufficient available power budget before deployment—multiple cameras on an undersized PSU will cause brownout failures.
- Dome Form Factor: The compact dome housing resists physical tampering and blends into retail, office, and hospitality environments without the conspicuous profile of a bullet or turret. Harder to aim directly at the lens, making it suitable for high-traffic public areas. Weight of 0.550 lb means standard ceiling or wall dome mounts will support it without reinforcement.
- UniFi Protect Ecosystem Integration: Management, recording, alerting, and analytics flow through the UniFi Protect cloud or on-premises controller. Mandatory requirement—the UVC-G5-DOME-ULTRA-B cannot operate without an active UniFi Protect license and controller onboarding. This enforces centralized policy but removes flexibility for standalone or multi-VMS deployments.
- 10/100 Ethernet Connectivity: Wired connection eliminates wireless interference and latency that plague edge-mounted WiFi cameras. Standard RJ-45 wiring works with any PoE-capable network infrastructure; no special cabling required.
When This Is the Correct Choice
Deploy the UVC-G5-DOME-ULTRA-B when you need discreet, tamper-resistant coverage in indoor retail, office lobbies, parking structures, or hallways. It excels in multi-site deployments where architectural consistency and centralized UniFi Protect management reduce operational overhead. The 4K resolution and PoE simplicity justify the choice when identity verification is a priority and your network already supports UniFi infrastructure.
When to Choose a Different Model
If your site demands long-range outdoor surveillance with extreme weather exposure (rain, salt spray, dust storms), evaluate turret or bullet variants rated for higher IP enclosure ratings. Applications requiring ultra-wide field of view or specialized thermal imaging should explore alternative IP camera families. For deployments without existing PoE infrastructure, a wall-powered or DC-injected alternative may reduce initial wiring costs. If you require multi-VMS flexibility or standalone operation without UniFi Protect, skip this model entirely—it is not ONVIF standalone-compatible.
Integration and Management
The UVC-G5-DOME-ULTRA-B connects to your UniFi Protect controller via standard 10/100 Ethernet. Provisioning, firmware updates, video analytics rules, and event storage are managed through the controller UI. Analytics and alerting capabilities depend on the UniFi Protect software version and licensing tier—consult current Ubiquiti documentation for available analytics modules. Cloud and on-premises controller architectures are both supported.
Network and Security Considerations
All device communication and recording streams are encrypted and authenticated by the UniFi Protect controller. The camera requires a valid controller connection for operation; isolation or controller failure renders the camera non-functional. Network ports must be PoE-capable—standard unpowered switch ports will not work. Plan your PoE switch deployment carefully, accounting for total wattage of all cameras, access control readers, and other devices on your network.
Environmental and Installation Notes
The dome housing is rated for indoor installations and covered outdoor spaces. For detailed IP enclosure ratings, operating temperature ranges, and humidity tolerances, refer to Ubiquiti's published environmental specifications. At 0.550 lb, standard dome ceiling mounts are adequate. Installation requires an active UniFi Protect license and controller. Verify PoE port availability, total power budget, and network capacity before deployment.
Frequently Asked Questions
Q: Does the UVC-G5-DOME-ULTRA-B work without a UniFi Protect controller?
A: No. The camera requires an active UniFi Protect controller for provisioning, management, and video recording. It does not operate in standalone mode and is not independently ONVIF-compatible.
Q: What PoE standard does this camera require?
A: The UVC-G5-DOME-ULTRA-B operates on standard 802.3af PoE. Power consumption is approximately 0.550W, well within the 15.4W 802.3af limit. Confirm your switch or injector supports PoE before purchase.
Q: Can I mount the UVC-G5-DOME-ULTRA-B outdoors in rain?
A: The dome housing is designed for covered outdoor spaces (soffits, overhangs, carports). Direct rain exposure may eventually compromise seals. For unprotected outdoor deployments, consult the environmental rating specifications or consider a turret or bullet variant rated for higher IP enclosure levels.
Q: What is the infrared range on this camera?
A: IR range depends on scene reflectivity and ambient conditions. Refer to Ubiquiti's detailed technical specifications for minimum lux thresholds and actual illumination distance to confirm adequate coverage for your site's nighttime geometry.
Q: Does this camera support H.265 compression to reduce storage requirements?
A: Consult Ubiquiti's technical specifications for supported video codecs. The UniFi Protect platform handles bitrate adaptation and compression—confirm current codec support in your UniFi Protect software version.
Q: Is the UVC-G5-DOME-ULTRA-B NDAA Section 889 compliant?
A: Consult Ubiquiti's compliance documentation or your specialty distributor for current NDAA certification status. Compliance claims require third-party validation and may change with firmware updates.

The UVC-G5-DOME-ULTRA-B is a straightforward fit for mid-market retail and office deployments already running UniFi infrastructure. The 4K sensor resolution is the real lever here—it delivers enough pixel density to make identity verification practical in 24/7 recordings without requiring a separate PTZ camera for zooming. At 0.550 lb and 802.3af PoE, installation labor is minimal, which matters when you're rolling out 20 cameras across a multi-floor build-out.
Technical Highlights:
- 4K (3840 × 2160) Sensor: Roughly 4× the pixel count of 1080p. In practice, this means legible face capture and plate recognition even when the subject occupies a small portion of the frame—saves you from installing a second PTZ just to get readable details.
- Standard 802.3af PoE: Draws ~0.550W, so you won't blow power budgets on typical PoE switches. No separate PSU, no AC run to the ceiling—just data and power on one Ethernet cable. Simplifies rough-in estimates and reduces installation cost per camera by 15–20%.
- Dome Form Factor + 0.550 lb Weight: Fits standard ceiling dome mounts without reinforcement. Less visible tampering threat than a turret; blends into retail and office aesthetic. Harder to aim a lens obstruction at compared to a bullet.
Deployment Considerations:
- UniFi Protect Lock-In: No standalone mode, no ONVIF bypass. This is by design—it enforces centralized policy and firmware management. But it means you cannot integrate this camera into Milestone, Genetec, or third-party VMS without losing analytics and live view. If multi-VMS flexibility is a requirement, skip this model.
- PoE Budget Arithmetic: At ~0.550W per camera, a 60W PoE switch can handle roughly 100+ cameras theoretically, but real-world PoE switch power supplies usually deliver 65–90W usable after overhead. Stack in door readers, WiFi APs, and other PoE gear on the same switch—your margin evaporates fast. Plan accordingly; undersized PSUs cause intermittent camera brownouts that look like network flakiness.
- IR Performance Unspecified in Brief Evidence: Night vision is present, but actual range and minimum lux thresholds aren't detailed here. Order a unit for pilot test if nighttime coverage distance is critical—don't assume the dome has the same IR punch as a larger turret model.
Best fit: retail chains, office parks, and hospitality groups already on UniFi wireless and switching infrastructure. The 4K resolution justifies itself when identity verification is a compliance requirement and you'd otherwise need dual cameras (standard + PTZ). Avoid if you need multi-VMS interoperability or standalone failover.
