Altronix NETWAY41BT 4-Port 90W Managed Midspan PoE Injector
Overview
The Altronix NETWAY41BT is a 4-port managed midspan PoE injector engineered to deliver up to 90W per port — 360W total — to high-draw surveillance and security devices on existing network runs. Where a standard PoE switch falls short on per-port power budget, this midspan slots cleanly into the infrastructure between your switch and the endpoints, adding the wattage without forcing a full switch replacement. If you're powering PTZ cameras, multi-sensor panoramic heads, or edge-computing devices that demand 60W, 75W, or the full 90W, the NETWAY41BT provides that headroom on every port simultaneously.
Managed operation means per-port visibility and control — critical when you need to remotely power-cycle a frozen device on a rooftop or inside a locked electrical room without a truck roll. Built-in overload protection and short circuit protection on each port prevent a single device fault from cascading to other ports, keeping the rest of your run operational while you address the problem.
Key Features
- 90W Per Port, 360W Total Budget: Each of the four ports can deliver the full 90W independently — relevant when powering PoE++ devices like pan-tilt-zoom cameras with integrated IR, multi-sensor heads, or IP speakers with built-in amplifiers. A 360W aggregate means you can run all four ports at max draw simultaneously without throttling.
- Managed Architecture: Remote per-port management lets you monitor port status, reboot individual endpoints, and respond to device faults from a central console — eliminating the need for physical access to restart a hung camera or access control reader in a hard-to-reach location.
- Overload Protection: Per-port overload protection shuts down a port the instant current draw exceeds safe thresholds, protecting both the injector and the connected device. Other ports remain live, so a single device failure doesn't take down adjacent cameras or intercoms.
- Short Circuit Protection: A wiring fault or connector failure won't damage the NETWAY41BT or propagate across the bus. The affected port isolates automatically, while the three remaining ports continue operating normally — important for installations where rewiring is disruptive or time-consuming.
- Midspan Form Factor: Inserts between any 802.3-compliant switch and your PoE endpoints without requiring a switch upgrade. If your existing switch infrastructure is solid but under-powered for newer high-watt devices, this is a cost-effective path to per-port 90W without replacing hardware that's otherwise performing well.
- 4-Port Density: Sized for closets, junction boxes, or small IDF enclosures where a full 8- or 16-port unit is excessive. Four ports cover a camera cluster, an entry-point access control setup, or a satellite equipment room efficiently without wasting rack or panel space.
Integration & Compatibility
The NETWAY41BT is designed to integrate into existing structured cabling plant and network infrastructure. As a PoE midspan injector, it works upstream of any PoE-capable endpoint — cameras, access control readers, IP intercoms, wireless access points — provided the device accepts 90W-class PoE input. Verify endpoint PoE class compatibility before deployment; not all devices can accept the full 90W and may negotiate to a lower class automatically per 802.3 handshake. For large-scale surveillance deployments, pairing this unit with a Altronix power and network product line provides a unified vendor approach for power distribution and infrastructure. When planning a multi-camera NVR-based system, midspan injectors like the NETWAY41BT are a practical bridge between legacy switch infrastructure and modern high-power camera heads. For help sizing your PoE power budget across a full deployment, reference the PoE planning guide to calculate aggregate draw and verify your switch uplink and cabling plant can handle the load. Installations requiring a full-rack PoE distribution strategy should also review surveillance power supplies alongside midspan options.
Frequently Asked Questions
Q: Can the NETWAY41BT deliver 90W on all four ports at the same time?
A: Yes. The total power budget is 360W — exactly 90W times four ports — so all four ports can operate at maximum draw simultaneously without the injector throttling any individual port.
Q: Does the NETWAY41BT work with standard 802.3af or 802.3at devices?
A: As a managed midspan, the NETWAY41BT supports high-watt PoE delivery up to 90W per port. Devices that negotiate to lower power classes (802.3af at ~15W or 802.3at at ~30W) will receive the power they request — the port simply won't source the full 90W unless the endpoint negotiates for it.
Q: What happens if one port experiences a short circuit?
A: Built-in short circuit protection isolates the affected port immediately. The remaining three ports continue operating normally, so a wiring fault or device failure on one run won't disrupt other endpoints on the injector.
Q: Is the NETWAY41BT a replacement for a PoE switch, or does it work alongside one?
A: It's a midspan injector, not a switch — it adds PoE power to data runs coming from an existing non-PoE or under-powered switch. Your switch handles switching and routing; the NETWAY41BT handles power delivery. You still need a switch upstream.
Q: What types of devices are appropriate loads for the NETWAY41BT?
A: Any PoE-powered endpoint that requires up to 90W per port — including high-power PTZ cameras, multi-sensor panoramic camera heads, IP intercoms with built-in amplifiers, or wireless access points with high radio density. Verify the endpoint's PoE class and wattage requirement before selecting port count and injector sizing.
Q: Can the NETWAY41BT be remotely managed?
A: Yes. The managed architecture supports per-port monitoring and control, enabling remote power cycling of individual ports without physical access to the unit — useful for resetting a frozen device in a remote or secured location.
The NETWAY41BT is one of those units I recommend specifically when an integrator is deploying high-watt PTZ cameras or multi-sensor heads on a backbone switch that maxes out at 30W per port. The 90W-per-port ceiling on this midspan covers virtually every high-draw PoE++ device on the market today, and since the 360W budget is non-shared across ports, you're not gambling on whether the switch's total power budget gets eaten by other devices on the same chassis.
Technical Highlights:
- 90W Per-Port Delivery: At the top end of PoE++ power delivery, 90W per port covers multi-sensor panoramic cameras, high-torque PTZs with integrated IR, and combination camera/speaker devices without requiring a separate power supply run to each device.
- Managed Per-Port Control: Remote power cycling from a management console means a technician doesn't need to roll a truck to reboot a hung camera on a third-floor exterior mount — you cycle the port, the device reboots, and you log the event.
- Independent Port Fault Isolation: Overload and short circuit protection operate per-port — a fault on port 2 doesn't touch ports 1, 3, or 4. In a four-camera cluster covering a single zone, keeping three cameras live during a fault beats taking the entire zone dark.
Deployment Considerations:
- This unit adds PoE power to existing data infrastructure — your upstream switch must still handle the data plane. Confirm the switch's uplink and backplane aren't already saturated before adding high-bitrate camera feeds through it.
- Verify PoE class negotiation behavior for each endpoint type before deployment. Some legacy or low-cost devices don't negotiate properly with high-watt injectors and may behave unexpectedly — test in a bench environment before field installation at scale.
The NETWAY41BT is the right call for a compact PTZ cluster at a parking structure or loading dock entry where you're running three or four high-draw cameras off a closet IDF that was never designed for PoE++ loads — it adds the wattage without a switch forklift upgrade and keeps each camera's power feed independently protected.
