Axis 01944-001 30W Outdoor Gigabit PoE Midspan
The Axis 01944-001 is an inline power injector designed to extend PoE infrastructure into remote outdoor locations where running power lines is impractical or where a centralized switch cannot reach. It bridges power and data across a single standard Ethernet cable, eliminating the need for separate electrical conduit runs on exterior walls, poles, or across campus-wide surveillance installations.
Key Features & Deployment Benefits
- 30W PoE+ Power Output (54VDC): Supplies enough power for high-draw outdoor devices like PTZ cameras, thermal imaging units, and powered access points. A standard PoE+ switch typically allocates 30W per port, making this midspan a direct substitute for extending a single camera run without straining your switch's power budget.
- Gigabit Ethernet (1000 Mbps): All four wire pairs carry data, supporting full 10/100/1000 Mbps throughput. This future-proofs the installation if you later need to upgrade to bandwidth-intensive analytics or multi-stream recording over a single run.
- IP66/IP67-Rated Aluminum Enclosure: Direct rainfall, salt spray, and dust ingress won't compromise the unit. IP66 means sustained water jets won't penetrate; IP67 allows temporary submersion. This rating directly translates to outdoor lifespan — no corrosion failures on salt-spray coasts or in high-humidity tropical deployments.
- Wide Operating Temperature Range (-40°C to +65°C / -40°F to 149°F): Operates in arctic cold and desert heat without thermal shutdown. Your midspan won't fail during extreme seasonal swings or on poorly shaded roof installations, a critical factor for unattended outdoor sites.
- Automatic PoE/PoE+ Detection: Intelligently detects device power requirements and supplies the appropriate power level. No manual configuration or DIP switches to toggle — connect the device and it works. This simplifies provisioning across mixed inventories of standard PoE and PoE+ equipment.
- Compact Footprint (170×140×60 mm): Wall or pole mounting keeps the midspan unobtrusive. Works with optional pole mounts for flexible placement on existing infrastructure without additional hardware purchases.
- Low Idle Power Consumption (2W idle, 36W with device connected): Running costs are predictable. A typical installation drawing 36W continuously (about 315 kWh annually) adds roughly $40 per year in electricity in most markets — negligible compared to installation labor.
- PVC-Free Construction: Meets environmental compliance requirements in regulated facilities or public-sector bids where hazardous material restrictions apply.
- 3-Year Manufacturer Warranty: Factory-backed coverage provides confidence in outdoor deployments where access is difficult and downtime is costly.
Integration & Compatibility
The 01944-001 works with any PoE or PoE+ device conforming to IEEE 802.3at/802.3bt standards. This includes Axis network cameras, third-party fixed domes, PTZ units, and powered outdoor access points. It supports standard Ethernet wiring (Cat5e or better) and does not require specialized shielded cabling for the device end — a cost saving on extended runs. The shielded RJ45 connectors and IP68-rated 3-pin AC power inlet handle outdoor weathering without additional weatherproof junction boxes.
Data and power separation follow IEEE conventions: pairs 1/2 and 3/6 carry 10/100 Mbps Ethernet; all four pairs carry Gigabit data. Power runs on pairs 4/5 (+) and 7/8 (-), leaving no overlap. This design ensures minimal crosstalk in noisy RF environments typical of industrial campuses or airports.
When to Choose a Different Model
If you require passive midspans (no power input needed), or if your application demands higher power outputs (60W or greater), evaluate higher-wattage models in the Axis power infrastructure family. For indoor-only deployments or where a traditional PoE switch can reach, a network switch is more cost-effective and offers additional port density.
Frequently Asked Questions
Q: Does the 01944-001 work with standard PoE (802.3af) devices?
A: Yes. The automatic detection feature ensures it supplies only the power necessary for the connected device. A standard PoE device drawing 13W will receive 13W; a PoE+ device drawing 30W will receive 30W.
Q: Can I daisy-chain multiple midspans?
A: No. Each 01944-001 supports one downstream device. For multiple cameras on separate runs, install one midspan per camera or use a multi-port PoE switch at the head end.
Q: What happens if the midspan loses power?
A: The downstream device loses both data and power. The device will not fall back to an unpowered state. Ensure the AC power input is connected to an uninterruptible power supply (UPS) or dedicated circuit if continuous operation is critical.
Q: Is the 01944-001 rated for coastal salt-spray environments?
A: The aluminum enclosure is corrosion-resistant, but IP66/IP67 ratings do not guarantee salt-spray immunity per ASTM B117. For true coastal deployments, consult the datasheet for material composition or request accelerated corrosion test data from the manufacturer.
Q: Can the 01944-001 power devices requiring more than 30W?
A: No. Maximum output is 30W. If your camera or access point requires 60W or more, you will need a higher-wattage injector or a direct PoE++ switch connection.
Q: What certifications does the 01944-001 hold?
A: The unit complies with IEC/EN/UL 60950-1, EN 62368-1, FCC Part 15 Class B, and additional safety/EMC standards detailed in the datasheet. Verify NDAA Section 889 compliance separately with your procurement team if required for federal projects.

The Axis 01944-001 midspan solves a specific but common pain point: extending PoE to a single outdoor device when running conduit back to the switch closet is costly or architecturally impractical. Its IP66/IP67 aluminum housing and -40°C to +65°C operating range ensure five-plus years of reliable operation in extreme climates — from northern warehouse rooftops to desert perimeters. The automatic PoE/PoE+ detection eliminates commissioning friction: no DIP switches, no firmware updates, no compatibility guessing. Plug it in, connect the camera, and move on.
Technical Highlights:
- 30W Power Budget: Matches a full PoE+ port on your switch, so you don't sacrifice power density. A PTZ camera drawing 25W won't starve other devices on the network.
- Gigabit Ethernet Over All Four Pairs: You're not limited to 100 Mbps data rates like older passive injectors. Bandwidth-hungry thermal or multi-megapixel cameras won't struggle.
- Compact Form Factor (170×140×60 mm): Wall or pole mounting keeps installation clean. No bulky external power supplies dangling from conduit.
- Efficient Power Draw (2W idle, 36W peak): Annual operating costs are negligible, making this a low-TCO solution for extended outdoor runs.
Deployment Considerations:
- The 01944-001 is a single-port injector. If you need to power multiple cameras on separate runs, budget one midspan per camera — don't underestimate this in cost estimates.
- AC power must be reliable. Consider UPS backup if the camera's uptime SLA is strict — a PoE midspan without power means total downtime, not graceful degradation.
- Salt-spray and extreme corrosion environments: IP66/IP67 ratings don't guarantee ASTM B117 salt-fog immunity. Request material test data before deploying on coastal piers or heavy-salt industrial sites.
This midspan is your go-to for single-camera outdoor extensions where switch proximity is a constraint but power budget and bandwidth aren't. Campus perimeters, remote gate houses, and roof-mounted PTZ applications all fit this profile. For multi-point deployments, a managed switch with sufficient PoE capacity remains more economical per port.
