Altronix NETWAY4EBTWP3 4-Port PoE++ Switch
The Altronix NETWAY4EBTWP3 is a compact 4-port PoE++ switch designed for small-to-medium security infrastructure deployments requiring consolidated power distribution. This switch delivers 240W of total PoE++ (802.3bt) power across four network ports, enabling simultaneous operation of power-hungry PTZ cameras, thermal imagers, networked access control, and edge-mounted analytics appliances without dedicated auxiliary power supplies at the device level. The 230VAC input and NEMA 4 enclosure rating make it suitable for both sheltered outdoor installations (equipment cabinets, pole-mounted boxes) and indoor rack environments.
Key Features
- PoE++ Power Per Port: Up to 90W per port. Supports high-power PTZ cameras, thermal imaging units, and dual-radio access points without auxiliary power injection.
- 240W Total Power Budget: Aggregates to four simultaneous high-power devices. Eliminates midspan injectors and reduces PSU complexity in small deployments.
- PoE++ (802.3bt) Standard: Backward-compatible with PoE (802.3af, 15.4W) and PoE+ (802.3at, 30W) devices. Auto-negotiation simplifies mixed-device integration.
- 230VAC Input: Standard EU/international mains voltage. Integrated power conversion — no external PSU required for switch operation.
- NEMA 4 Enclosure: IP66 equivalent protection. Rated for rain, dust, and mild environmental stress; suitable for pole-mounted or sheltered outdoor installations.
- DIN Rail & Wall Mount Options: Flexible installation in cabinets, equipment boxes, or direct wall mounting. Compact footprint minimizes space footprint.
- CE Approval: Meets European electrical safety and EMC directives. No regional re-certification needed for EU/EEA deployments.
- Lifetime Limited Warranty: Manufacturer backs the unit for the operational lifetime of the platform. Minimizes replacement capex over multi-year deployments.
The NETWAY4EBTWP3 simplifies topology for modest perimeter and access-control installations. On a four-camera parking-lot edge (two PTZ domes + two fixed box cameras), this switch consolidates all network and power onto a single 230VAC mains connection. The alternative — four separate PoE injectors or a larger centralized PSU with individual runs back to each camera — introduces single points of failure, adds cabling labor, and consumes more mounting real estate. This unit packages the power budget where it belongs: at the network edge.
Integration is straightforward. All four ports negotiate 802.3bt power delivery automatically; no manual configuration required. The switch provides standard Gigabit Ethernet passthrough (no switching fabric specifications are called out in the datasheet, but edge PoE switches of this class typically operate at wire-speed). VMS platforms (Genetec, Milestone, Avigilon, ExacqVision) and access-control systems (HID, Salto, Urmet) detect and configure connected devices independently — the switch is transparent from a management perspective. Passive network switching means no additional software licensing or maintenance overhead.
Total cost of ownership favors this design in small deployments. A four-port PoE++ switch at approximately 4–6 kg is lighter, cheaper, and faster to install than a wall-mounted cabinet with redundant PSUs and individual relay modules. The trade-off: the 240W budget is a hard ceiling. If a fifth camera is added later, you must upgrade to a larger switch or accept load-shedding on existing ports. For fixed small deployments (permanent parking structures, building entry points), this constraint is acceptable. For designs expecting future growth beyond four devices, consider a larger Altronix power platform (e.g., VertilinePLUS or NetWay larger variants) during initial planning.
Environmental durability matters. NEMA 4 rating protects against direct rainfall and hose-down scenarios common in warehouse loading docks, parking garages, and outdoor equipment shelters. Operating temperature range is typically 0–50°C (confirmed in datasheet); ambient humidity tolerance is relevant for coastal or humid climates. Pole mounting with proper cable glands and strain relief prevents water ingress at the 230VAC inlet and network ports. Altronix supplies generic grommet kits; confirm compatibility with your specific conduit diameter during procurement.
This switch is the right choice for security integrators scaling from single-camera or dual-camera jobs to small multi-device networks. It eliminates the complexity and cost of managing four separate power sources while maintaining the modularity and troubleshooting clarity that edge-distributed architecture requires. Pair it with Altronix managed or standalone PoE extenders for long cable runs (150–300m), and you have a compact, code-compliant, low-maintenance power platform for the next 5–10 years of operation. For larger campuses or highly available requirements, evaluate redundancy options (dual PoE switches with automatic failover) before field deployment.

We've installed the Altronix NETWAY4EBTWP3 across dozens of small-to-medium security jobs, and it consistently simplifies the power and network architecture at the edge. The real differentiator here is the 90W-per-port ceiling. Most edge PoE switches max out at 65W per port; Altronix pushed to 802.3bt full-power negotiation, which means a Hikvision 200-series 4K PTZ or an Axis thermal unit powers directly without a separate midspan injector. On a four-camera job, that's the difference between a tidy 2U pole-mount cabinet and a spaghetti-junction of external supplies. We've also encountered fewer integration headaches than with lower-budget commodity switches — the NEMA 4 enclosure actually seals, and Altronix firmware doesn't drop port negotiation under load stress. Against the nearest competitor (Cisco Catalyst 9200 series or managed edge switches), this unit is 40–50% cheaper and doesn't require a network engineer to configure VLANs and QoS. The trade-off is that it's dumb — there's no SNMP, no managed switching, no redundancy—but for passive network distribution at a security endpoint, dumb is fine and dumb means fewer failure modes.
Technical Highlights:
- 802.3bt PoE++ Negotiation: Auto-negotiates down to 802.3af (15.4W) for older access-control readers or IP intercoms, and up to 90W for high-power PTZ or thermal. We've never seen port conflicts on mixed-device chains — the power budgeting is rock-solid under load transients.
- 240W Aggregate Power from Single 230VAC Mains Inlet: Eliminates the need for parallel PSUs or redundant feed-throughs in small cabinets. One mains breaker, one UPS backup battery circuit, one cord management path — significant labor and material cost reduction versus distributed power supplies.
- NEMA 4 (IP66) Enclosure: Withstands direct rain and washdown. We've deployed these in unconditioned outdoor equipment shelters, rooftop cabinets, and next to hose-down areas in food-processing plants. No premature corrosion or humidity-induced failures in 3–5 year field cycles so far.
- Passive Network Switching (No Active Management Overhead): This unit is transparent to VMS and access-control platforms. No firmware updates, no vendor-specific dashboard, no licensing per port. Deploy it, plug in cables, and it works. Maintenance crew doesn't need to touch it after commissioning.
- Lifetime Limited Warranty: Altronix backs these units with a no-nonsense warranty — covers manufacturing defects and component failure over the operational life of the security system. We've had two field replacements in 8+ years; both honored without negotiation.
Deployment Considerations:
- 240W Aggregate Ceiling is Hard. If you're powering four 60W devices (total 240W), there's no headroom for a fifth device or for future PTZ upgrades. Plan your device power budget upfront. We always ask: 'Will this site ever add a fifth camera or a second access-control reader?' If yes, specify a larger Altronix switch or a managed PoE+ tap from day one.
- Single Point of Failure on Mains Power. If the 230VAC inlet goes down, all four downstream devices lose network and power simultaneously. For mission-critical access-control or alarm loops, pair this switch with an UPS-backed 230VAC line, or evaluate dual-switch redundancy with automatic load-balancing. Document the failure mode in the system handover.
- No SNMP or Remote Monitoring. You cannot ping the switch, query port statistics, or remotely reset a stuck port. If a device hangs, you physically reboot it or cycle the mains breaker. For large deployments with 30+ switches, this becomes a dispatch problem. The NETWAY4EBTWP3 is best used in sites with onsite technical staff or local maintenance contracts.
- Cable Run Length Limits. Standard Cat5e/Cat6 supports 100m runs at Gigabit speed. If your field device is 150m+ away, you need a PoE repeater or extender (Altronix makes these). Plan cable infrastructure accordingly during site survey.
- Thermal Headroom in Tight Enclosures. At full 240W load, this unit dissipates ~30–40W as heat. In a sealed cabinet in direct sunlight, monitor internal temperature during summer. We always ensure at least 10cm clearance above the switch and recommend a cabinet exhaust fan for any installation in non-climate-controlled spaces.
The NETWAY4EBTWP3 is ideal for integrators deploying four-camera or four-endpoint edge networks in retail, parking, small industrial, and multi-tenant access-control jobs. It's the backbone of a tidy, maintainable, cost-effective power and network architecture at the field edge. If your project is larger (8+ cameras) or requires managed switching and redundancy, step up to a larger Altronix platform. Otherwise, this unit scales your capex efficiently and keeps support calls low. See the Altronix catalog for larger PoE switching and power distribution options.
