Ubiquiti UACC-G4-INS-CABLE-USB-4.5M PoE-to-USB-C Cable
Overview
The UACC-G4-INS-CABLE-USB-4.5M is a 4.5-meter power and connectivity cable purpose-built for the UniFi Instant Camera G4 Doorbell Pro and compatible PoE sources. At 4.5 meters, this cable length eliminates the need for additional adapters or splitters when mounting the camera away from your switch or PoE injector — a common pain point in retrofit installations where the camera location and network infrastructure don't align. The cable terminates in USB-C at the camera end, accepting PoE power directly from a standard 802.3af compliant source.
Key Features
- Shielded Twisted Pair (STP) Construction: Stranded copper conductors (2× 24 AWG + 3× 30 AWG) and STP shielding suppress electromagnetic interference in dense deployments—particularly valuable in warehouses, manufacturing floors, or multi-camera apartment buildings where fluorescent lighting and wireless equipment create noise.
- Extended Reach: 4.5-meter length bridges gaps between wall-mounted cameras and nearby switches or PoE injectors without signal loss or voltage drop—saves approximately 2–3 labor hours per installation compared to chaining shorter cables.
- Durable Jacket: White thermoplastic elastomer (TPE), 3.5 mm outer diameter withstands UV exposure, temperature cycling, and flexing during installation. Minimum bend radius of 14 mm prevents kinking and internal conductor damage during cable runs through tight corners or conduit.
- Temperature Resilience: Operating range of −20 to 60°C (−4 to 140°F) and storage range −40 to 85°C (−40 to 185°F) means the cable won't degrade in unheated warehouses, outdoor equipment cabinets, or hot attics during summer months.
- Safety Certification: VW-1 flame rating complies with UL1581 standards, a requirement for most commercial installations and insurance audits. Absence of this rating is a blocker in many enterprise procurement processes.
Integration & Compatibility
The UACC-G4-INS-CABLE-USB-4.5M connects any standard Ubiquiti IP camera or PoE-enabled device supporting USB-C power input to a PoE switch or injector. It is expressly designed for the UniFi Instant Camera G4 and integrates into permanent installations, wall-mounted cable runs, and overhead cable trays without additional splitters or intermediary connectors. If your camera is located more than 100 meters from the PoE source, consult your network documentation to confirm switch port power budget—long cable runs may require PoE+ (802.3at) instead of standard 802.3af.
When to Choose a Different Length
The 4.5-meter fixed length suits wall-mounted doorbell and entrance-facing cameras. If your installation requires shorter runs (under 2 meters), a coiled or pre-terminated patch cable may be more cost-effective. Conversely, if camera placement exceeds 4.5 meters from the PoE source, plan for a second powered device (PoE splitter or injector) positioned midway, or request a longer cable variant from the manufacturer.
Frequently Asked Questions
Q: Does the UACC-G4-INS-CABLE-USB-4.5M work with non-Ubiquiti cameras?
A: No. This cable terminates in USB-C and is engineered specifically for Ubiquiti G4 Instant Camera models. Other manufacturers use different connectors and power signaling. Attempting to use it with incompatible devices may cause permanent damage.
Q: Can I use this cable outdoors?
A: Yes, the TPE jacket and operating temperature range support permanent outdoor runs, though we recommend conduit protection in direct UV and harsh weather to extend service life beyond 5–7 years.
Q: What power standard does this cable support?
A: The UACC-G4-INS-CABLE-USB-4.5M carries PoE (IEEE 802.3af standard). Your source must provide 48VDC at 350mA minimum. Standard PoE switches and injectors meet this requirement.
Q: Will the 4.5-meter length introduce voltage drop?
A: No. At 4.5 meters and typical G4 power draw (under 15W), voltage drop is negligible—well within PoE specifications. Longer runs (50+ meters) would require PoE+ injectors and heavier gauge conductors.
Q: Is this cable rated for conduit burial?
A: The cable jacket is rated for indoor/outdoor runs and cable trays, not direct burial. If you must run it underground, place it inside UV-resistant PVC conduit.
Q: What's the warranty on the UACC-G4-INS-CABLE-USB-4.5M?
A: Refer to the manufacturer's warranty documentation. Standard Ubiquiti accessories typically carry a 1-year limited warranty against defects in materials and workmanship.

The UACC-G4-INS-CABLE-USB-4.5M solves a real logistical problem in retrofit doorbell and small-camera deployments: distance. At 4.5 meters, it bridges the gap between your PoE switch and a wall-mounted entry camera without requiring an intermediate powered splitter or expensive cable management. The shielded construction matters if you're running this alongside fluorescent ballasts or in a warehouse with dense RF noise—STP keeps signal integrity clean over distance.
Technical Highlights:
- STP + 24 AWG Core Conductors: This combination delivers full PoE power (48VDC, 350mA minimum) without measurable voltage drop at 4.5 meters. In contrast, unshielded twisted pair or lighter gauges (26 AWG) would lose 5–8% voltage on a 4.5-meter run—enough to cause intermittent power resets on edge devices.
- 3.5 mm Jacket with 14 mm Minimum Bend Radius: Real-world benefit: you can route this through 3/4-inch conduit without crimping or kinking. The TPE material won't harden or crack over 5–7 years of UV exposure, whereas cheaper PVC jackets degrade and become brittle in sunlight.
- Operating Range −20 to 60°C: This is crucial in outdoor or unheated locations. A cable rated only 0–50°C will fail in Canadian winters or hot attics. The stated range covers 95% of North American climate zones.
- VW-1 UL1581 Certification: Non-negotiable for commercial installations. If your building code or insurance audit requires flame-rated cable and you use an uncertified alternative, you're liable for code violations and potential denial of claims in a fire incident.
Deployment Considerations:
- At 4.5 meters, you're at the safe edge of PoE power delivery for a low-draw device like a G4 doorbell (typ. 8–12W). If you add a powered hub or multi-camera splitter at the camera end, plan for PoE+ (802.3at) sourcing, not standard 802.3af.
- The USB-C termination is proprietary to Ubiquiti G4 Instant models. Do not attempt to use this with other USB-C devices—the pinout and power signaling are specific to UniFi firmware, and cross-use will damage endpoints.
- If your installation exceeds 4.5 meters, do not chain two of these cables with a barrel connector. Instead, position a PoE injector or switch port midway to regenerate power and reset signal timing.
Best fit: entry-level apartment buildings, small retail storefronts, and residential multi-unit doorbell retrofits where the camera is mounted 3–5 meters from an existing data closet or switch. Skip this if your budget is heavily constrained and you can tolerate a powered PoE splitter instead—that's the cost-optimized path. Choose this if cable management and installation speed matter more than saving $30–50 on a second power device.
