Axis 5026-401 PoE+ Over Coax Adapter Kit

Axis 5026-401 PoE+ Over Coax Adapter Kit

The 5026-401 (often searched as 5026 401) bridges legacy analog infrastructure and modern IP surveillance. This adapter kit transmits both PoE+ power and Ethernet data over existing 75-ohm coaxial cable, eliminating the need to replace cable runs during upgrades to IP-based systems. For security integrators and facility managers working in warehouses, retail, or enterprise environments, this means faster deployment, lower labor cost, and zero disruption to established infrastructure.

Key Features

• 500-meter (1600 ft) coax extension: Reaches across large facilities or between buildings without requiring new cable trenching or conduit runs — a significant cost and time savings on greenfield and retrofit projects alike.
• 25.5 W power delivery over coax: IEEE 802.3af/at compliant output means it supplies enough current for most fixed cameras, pan-tilts, and illuminators without a separate power supply at the far end. In tight cable management scenarios, this eliminates another breaker and outlet.
• 100 Mbps symmetrical data rate: Full-duplex 100 Base-TX Ethernet over the coax link ensures adequate throughput for single or dual-stream HD and 4MP cameras; not suitable for 4K multi-camera aggregation on a single pair.
• Auto-detection and auto-cutout safeguards: Prevents power delivery to non-compatible devices or damaged cable runs, protecting both the adapter and connected equipment from fault conditions.
• Compact wall, rack, or DIN-rail housing: 104 × 54 × 24 mm form factor fits in cabinets, utility closets, or above drop ceilings without requiring dedicated enclosure space — important when real estate is constrained.
• LED status indicators: Network and power LEDs show link and power status at a glance, reducing troubleshooting time in the field.
• 5-year warranty: Manufacturer-backed coverage for the adapter unit itself, though warranty does not extend to existing coax plant.

Integration & Compatibility

The 5026-401 accepts BNC 75-ohm connectors on the coax side and shielded RJ45 on the Ethernet side. It draws power from an external PoE+ source (PoE injector, PoE+ switch port, or 44–57 V DC supply rated for 0.7 A maximum). Operating range spans -10°C to 50°C, making it suitable for indoor rack, ceiling, or wall installations in climate-controlled spaces but not for outdoor cabinets or unheated utility areas. Maximum humidity tolerance is 95% RH non-condensing; condensation or direct moisture will cause failures.

On Axis IP cameras and compatible third-party devices, the 5026-401 acts as a transparent Ethernet extension — no configuration or firmware changes required on the camera side. When paired with a network video recorder, it extends reach without requiring a secondary PoE+ injector at the camera end.

When to Choose a Different Approach

If your coax runs are damaged, severely kinked, or exceed 500 m, or if you need to aggregate multiple 4K cameras on a single link, a dedicated fiber converter or fiber-optic cable pull may deliver better long-term reliability. Similarly, if your facility lacks existing coax plant, the labor to replace it with Cat6A or higher is often similar to the cost of a structured cabling retrofit — calculate the total cost of ownership before deciding.

Frequently Asked Questions

Q: Can the 5026-401 be mounted on a PoE+ switch port directly?

A: Yes. Any PoE+ port (802.3at Class 4 or higher) on a managed or unmanaged switch can supply the adapter's 44–57 V DC input. No separate injector is required in that scenario.

Q: What happens if I exceed 500 m of coax?

A: Signal attenuation will degrade Ethernet frame integrity and power delivery. The auto-cutout should protect equipment, but data loss and link drops become probable. Respect the 500 m limit.

Q: Does this kit include the coaxial cable?

A: No. You must supply or install standard 75-ohm coaxial cable between the two adapter ends. The kit includes only the transmit and receive adapter units.

Q: Is the 5026-401 suitable for outdoor cable runs?

A: The adapter units themselves are indoor-rated (-10°C to 50°C). Outdoor coax is acceptable if the adapter enclosures remain in a climate-controlled cabinet or rack. Do not mount the adapters in an external junction box without additional weatherproofing.

Q: Will the 5026-401 work with analog BNC cameras still on the coax line?

A: No. The adapter assumes the coax carries Ethernet and PoE signaling. Analog video and power on the same pair will conflict. Migrate all cameras on that run to IP before deploying the adapter.

Q: What is the power consumption of the 5026-401 adapter itself?

A: The adapter consumes minimal power (a few watts for the electronics). The majority of the 25.5 W budget is reserved for downstream device power — cameras, illuminators, or heating elements.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The 5026-401 solves a real problem: you have kilometers of existing coax plant, you need to migrate to IP, and your budget doesn't accommodate a full cable replacement. This adapter kit delivers 25.5 W over 500 m of coax — enough for a fixed camera and modest auxiliary load, but not a power-hungry PTZ or heater unit without supplementary DC injection.

Technical Highlights:

• 500 m reach on 75-ohm coax: Practical distance for campus deployments, parking structures, and large warehouses where cable runs were originally designed for analog camera pairs. Exceeding this distance introduces attenuation that auto-cutout will detect.
• 100 Mbps full-duplex Ethernet: Adequate for H.264 single-stream 1080p or dual-stream 2MP. Not suitable for 4K aggregation or high-bitrate motion JPEG; verify camera bandwidth profile before deployment.
• IEEE 802.3af/at power budget (25.5 W max): Standard PoE+ class output. Most fixed-dome and turret cameras draw 5–15 W; pan-tilts and rapid-IR turrets may exceed this and require secondary 24 VDC injection at the far end.

Deployment Considerations:

• Auto-detection prevents live power-up faults, but you must still test the coax run for continuity and impedance before field installation — a broken or severely kinked pair will trigger cutout and leave the camera dark.
• Watch the temperature range: -10°C to 50°C is indoor only. Do not mount adapters in exterior cabinets or conduit without active climate control. Condensation in cold dawn or humid summer air will fail the unit within hours.

This kit is the smart choice for retrofit projects where coax is your only existing pathway and replacing it costs more than two years of your labor budget. Deploy it in climate-controlled racks, utility closets, or above drop ceilings — not in damp basements, unheated parking structures, or outdoor junction boxes.
