Altronix NETWAY4E1BTX 4-Port PoE++ Managed Switch with SFP Uplink
Overview
The Altronix NETWAY4E1BTX is a compact surveillance-grade PoE++ switch engineered for security integrators who need to power high-demand edge devices — pan-tilt-zoom cameras, multi-sensor imagers, and access control readers — from a single, field-ready enclosure. Four 10/100/1000 Mbps PoE++ ports backed by a 240W power budget, a dedicated Gigabit SFP uplink for fiber backhaul, and a wide -30°C to 55°C operating window make this unit a credible choice for installations that live in mechanical rooms, parking garages, or any environment where temperature swings are a daily reality. The NETWAY4E1BTX ships with a 56VDC input supply already integrated, eliminating the separate-power-supply coordination that plagues multi-vendor deployments.
This sits inside the Altronix NetWay product line, a family of power-over-Ethernet distribution products aimed squarely at surveillance infrastructure. If you're specifying a PoE network switch for a mid-size camera deployment and every port needs to carry a demanding device, the math here is straightforward: four ports, 90W each, 240W total system budget.
Key Features
- 90W PoE++ per port (IEEE 802.3bt): Each of the four ports delivers up to 90W — the full 802.3bt envelope. That headroom supports PTZ cameras (typically 25–45W), multi-sensor panoramic units (up to 60W), heated camera housings, and high-powered access control hardware without splitting hairs over port wattage. Older 802.3af/at switches would require a secondary injector for the same load; this unit handles it natively.
- 240W aggregate power budget: With all four ports loaded simultaneously, you have a real 240W pool to draw from. That works out to 60W per port at full utilization — more than enough for 802.3at devices at every port, with headroom if only one or two ports carry 802.3bt-class devices. This is the number that determines whether you can fully populate the switch without derated performance.
- IEEE 802.3af/at/bt auto-negotiation: The switch auto-detects what each connected device actually needs, rather than forcing you to configure per-port power classes manually. Plug in a basic 802.3af IP camera alongside a 802.3bt PTZ and both receive exactly the wattage they negotiated — no manual per-port tuning required on a busy install day.
- One Gigabit SFP uplink: The fiber uplink slot gives you a distance-unlimited backhaul path to your core switch or NVR. For camera runs that exceed the 100m copper limit — say, a warehouse perimeter or a campus parking structure — inserting a single-mode SFP module removes the distance constraint entirely without requiring an additional media converter in the cabinet.
- Integrated 56VDC power supply: Altronix builds the power supply into the enclosure rather than shipping an external brick. On a retrofit install where panel space is at a premium, not having to rack-mount a separate supply and run DC cables to the switch chassis can save meaningful cabinet space and reduce single points of failure.
- NEMA 1 enclosure, -30°C to 55°C operating range: NEMA 1 covers indoor installations against incidental contact, while the -30°C floor handles unheated mechanical spaces and sub-freezing storage-room deployments without any supplemental heating. The 55°C ceiling covers most equipment rooms even without air conditioning, and the 85°C storage rating means the unit can sit in a hot warehouse dock before installation without incurring thermal damage.
- CE agency listing: CE marking confirms this unit has been evaluated against European electromagnetic compatibility and low-voltage directives, which matters for any deployment shipping into EU member states or requiring documented compliance sign-off from a facilities or IT team.
