Altronix NETWAY4E1BTWP3 4-Port 802.3bt Outdoor PoE Switch with SFP Uplink
Overview
The Altronix NETWAY4E1BTWP3 is a hardened, weatherproof managed PoE switch purpose-built for outdoor surveillance and access control edge deployments where camera power budgets are high and cabinet space is limited. Packaging four 10/100/1000 Mbps PoE++ ports, one SFP Gigabit fiber uplink, and a 360W total power budget inside a NEMA 4/4X, IP66-rated enclosure, it handles multi-sensor PTZ cameras, pan-tilt domes, and high-wattage devices that exceed what standard 802.3at switches can deliver — all from a single self-contained unit that mounts directly at the field edge without a separate power supply or indoor enclosure.
For integrators deploying Altronix network power solutions or specifying high-power outdoor IP cameras, the NETWAY4E1BTWP3 eliminates the need to run AC power to a secondary enclosure, reduces conduit and wiring labor, and keeps the installation compliant with outdoor-rated requirements in a single unit rated for ambient temperatures from -30°C to 70°C.
Key Features
- Four IEEE 802.3bt Ports (90W Each): 802.3bt — also called PoE++ or 4PPoE — delivers up to 90W per port, which means this switch can power multi-sensor cameras, heated PTZ housings, and dual-radio wireless access points that 802.3at (30W) cannot reach. You get full protocol backward-compatibility with 802.3af and 802.3at devices on the same switch without manual configuration.
- 360W Total Power Budget: With all four ports loaded, the 360W aggregate budget is enough to run four 90W devices simultaneously — a real differentiator against 802.3at switches that cap at 120–150W total. For PTZ cameras with integrated heater/blower assemblies drawing 60–75W, that means headroom to spare rather than juggling port priorities.
- One Gigabit SFP Uplink: Fiber uplink breaks the distance limitation of copper Ethernet (100m) and eliminates ground-loop risk in multi-building installations. Run a single-mode SFP module and you can backhaul this edge switch from distances measured in kilometers, not meters — a practical requirement for campus perimeters, parking structures, and transportation hubs.
- NEMA 4/4X, IP66-Rated Enclosure: NEMA 4X adds corrosion resistance beyond standard NEMA 4, making it suitable for coastal and industrial environments where salt air, chemicals, or pressure washing are concerns. IP66 confirms protection against powerful water jets from any direction. This is not a light-duty outdoor housing — it's rated for direct weather exposure without additional shelter.
- -30°C to 70°C Operating Range: Most commercial PoE switches stop at 0°C or -10°C. At -30°C, this unit continues operating through Minnesota winters, high-altitude installations, and unheated utility enclosures without auxiliary heat. The 70°C upper limit handles direct sun loading on a dark enclosure in desert climates.
- 54VDC Output at 6.4A Continuous: Higher bus voltage (54V versus the 48V common in enterprise switches) improves power delivery efficiency over longer cable runs — reducing the voltage drop that causes marginal PoE devices to reset or underperform at the cable end of a 90-meter run.
- AC Input Flexibility — 115VAC or 230VAC: Universal AC input means the same SKU deploys internationally and avoids voltage-matching errors on mixed-voltage job sites. The 5A/250V input fuse provides overcurrent protection without requiring an external breaker per enclosure.
- Battery Backup Compatibility: The unit accepts sealed lead-acid or gel-type batteries, enabling UPS backup integration at the edge — cameras and door controllers stay online during a utility outage without running backup wiring back to a central UPS. This is a meaningful design point for gate access and critical perimeter coverage nodes.
Integration & Compatibility
The NETWAY4E1BTWP3 is designed to integrate with any PoE-powered network device conforming to IEEE 802.3af, 802.3at, or 802.3bt standards. High-wattage PTZ cameras, multi-imager panoramic cameras, and 802.11ax outdoor access points all fall within the 90W-per-port envelope. The SFP uplink is media-agnostic — pair it with a single-mode or multimode SFP transceiver matched to your fiber plant. For broader system planning, review a PoE switch selection guide to verify port power budgets against your camera load list before specifying. Battery backup wiring should conform to the battery manufacturer's sealed-lead-acid maintenance and ventilation requirements; the enclosure's IP66 rating assumes the battery compartment is sealed per installation instructions.
CE-certified for European deployments. Verify local jurisdiction requirements for outdoor electrical enclosures before installation. The NETWAY4E1BTWP3 does not include managed switching features such as VLAN, QoS, or SNMP — if those are required, specify a managed-layer variant. Compatible network video recorders and VMS platforms connect via the SFP uplink at the headend without additional configuration beyond standard IP addressing.
Frequently Asked Questions
Q: How many watts can each port on the NETWAY4E1BTWP3 deliver?
A: Each of the four ports supports up to 90W under IEEE 802.3bt (PoE++). The total system power budget is 360W, which supports all four ports at full load simultaneously.
Q: What is the operating temperature range of the NETWAY4E1BTWP3?
A: The unit operates from -30°C to 70°C, making it suitable for harsh outdoor environments including cold-climate installations and high-temperature enclosures in direct sunlight.
Q: Does the NETWAY4E1BTWP3 work with standard 802.3af and 802.3at cameras?
A: Yes. The ports are backward-compatible with IEEE 802.3af (15.4W) and 802.3at (30W) devices. You can mix lower-power cameras with high-wattage devices on the same switch.
Q: Can the NETWAY4E1BTWP3 be connected to a battery backup system?
A: Yes. The unit is designed to accept sealed lead-acid or gel-type batteries for UPS-style backup at the field edge, keeping connected cameras and devices online during AC power interruptions.
Q: What type of uplink does the NETWAY4E1BTWP3 use?
A: It includes one Gigabit SFP port for fiber uplink, which eliminates the 100-meter distance limitation of copper Ethernet and removes ground-loop risk in multi-building installations.
Q: What enclosure rating does the NETWAY4E1BTWP3 carry?
A: The enclosure is rated NEMA 4/4X and IP66, providing protection against corrosion, dust ingress, and powerful water jets from any direction — suitable for direct outdoor exposure without additional housing.
The NETWAY4E1BTWP3 is one of the few edge PoE switches I'd specify without hesitation for an uncontrolled outdoor cabinet. The 360W total budget at 90W per port isn't a marketing number — it's a genuine 802.3bt implementation that lets you run four high-wattage PTZ cameras or heated multi-sensor domes from a single self-contained unit, without sizing a separate power supply or cramming a second enclosure into a pole base.
Technical Highlights:
- 90W Per Port (802.3bt): At 90W per port, you can power current-generation multi-sensor PTZ cameras with integrated heater/blower assemblies that draw 60–80W — devices that simply cannot run on a 30W 802.3at port without brownout resets in cold weather.
- 54VDC Bus Voltage: The 54VDC output at 6.4A continuous is above the 48V norm and reduces resistive voltage drop on long cable runs — directly relevant when your camera is at 85 meters of 24 AWG and marginal voltage compliance causes intermittent PoE renegotiation.
- -30°C to 70°C Operating Range: Most hardened switches stop at -20°C. The extra 10°C of cold tolerance matters in upper Midwest and Canadian installations where January ambient inside an unheated riser can hit -25°C before you account for wind chill on an exposed cabinet.
Deployment Considerations:
- The SFP port is media-agnostic, but you must specify your own SFP transceiver matched to the fiber type and distance — budget for this in your BOM if the unit is being quoted all-inclusive.
- This is an unmanaged switch: no VLAN segmentation, no per-port QoS, no SNMP monitoring. If your VMS requires network segmentation between camera and management VLANs at the edge node, you'll need a managed-layer switch instead — the NETWAY4E1BTWP3 is not the right tool for that requirement.
The NETWAY4E1BTWP3 is the right call for perimeter surveillance nodes at transportation hubs, parking structures, and campus entry points where four high-draw cameras feed over a single fiber run back to the headend — particularly where winter temperatures or coastal corrosion rule out standard commercial hardware.
