Altronix NETWAY1BTS 90W 802.3bt PoE++ Midspan Injector with Dry Contact Shutdown
Overview
The Altronix NETWAY1BTS is a single-port 802.3bt PoE++ midspan injector that delivers up to 90W to a powered device over standard CAT5e or better cabling — enough headroom to drive high-draw PTZ cameras, multi-sensor units, access control readers with electric locks, and other power-hungry edge devices that standard PoE+ switches simply cannot feed. Designed for Altronix's commercial security line, the NETWAY1BTS adds a practical field feature that most commodity injectors skip: a dry contact shutdown input that lets an external control signal cut PoE power on demand, enabling camera or device lockout scenarios without touching the network switch. If you're integrating into a larger PoE infrastructure where managed power cycling or alarm-triggered shutdown is part of the design, this injector belongs in that conversation.
Key Features
- 90W IEEE 802.3bt Output: The full 90W envelope (PoE++ Class 8) covers devices that 802.3at PoE+ maxes out at 30W cannot power — specifically useful for high-speed PTZ cameras with integrated IR and heaters, or multi-door access panels. You don't need a separate local power supply for the endpoint.
- Dry Contact Shutdown Trigger: An external dry contact input cuts PoE output on closure — no IP command, no managed switch required. Use this to tie camera power to an alarm panel output, a key-switch, or a building automation relay. This is the differentiating spec on the NETWAY1BTS and the reason to choose it over a generic injector.
- Dual Voltage AC Input (115VAC / 230VAC): Auto-range or dual-rated input handles both North American and international mains. Input current is 1.2A at 115VAC or 0.75A at 230VAC — verify your circuit breaker budget if you're running several units in the same panel.
- Gigabit Data Pass-Through (10/100/1000 Mbps): The data path runs at full Gigabit speeds, so high-bitrate video streams from 4K or multi-sensor cameras won't be throttled by the injector. Copper runs stay clean up to the standard 100m limit on CAT5e or better.
- 100m Reach on Standard Cabling: Full IEEE distance compliance means you can drop this injector at an IDF closet or wall-mount enclosure and reach any device within a standard structured-cabling segment — no fiber or extenders needed for typical building runs.
- Wide Operating Temperature (-30°C to 55°C): The -30°C cold-start rating makes this viable in unheated closets, parking garage enclosures, or outdoor-rated junction boxes in cold climates — environments where commodity injectors derate or fail to initialize.
- Compact Form Factor (1.7" x 4.1" x 7.2", 2.2 lb): The slim footprint fits inside standard surface-mount enclosures or on a DIN-adjacent shelf without consuming a full rack U. At 2.2 lb it won't stress lightweight enclosure mounting plates.
Integration & Compatibility
The NETWAY1BTS works with any 802.3bt-compliant powered device — there's no Altronix-proprietary negotiation. Pair it with PTZ cameras, 360-degree panoramic units, or access control panels drawing up to 90W. The dry contact input integrates with virtually any alarm panel or relay output that provides a normally-open or normally-closed contact closure. For multi-camera deployments where managed power cycling is required across many ports, evaluate a managed PoE switch with per-port SNMP control alongside this unit for single high-draw endpoints. Review your PoE planning before sizing the upstream infrastructure — a single 90W port draws as much as six standard 802.3af ports simultaneously.
Frequently Asked Questions
Q: What PoE standard does the NETWAY1BTS support?
A: The NETWAY1BTS supports IEEE 802.3bt (PoE++), delivering up to 90W to a single powered device over CAT5e or better cabling.
Q: How does the dry contact shutdown work?
A: A dry contact input on the unit cuts PoE output when triggered by an external contact closure — such as an alarm panel relay, key-switch, or building automation output. No network command or managed switch is required to execute the shutdown.
Q: What cabling does the NETWAY1BTS require?
A: The unit requires 4-pair CAT5e or better cabling. Maximum supported distance is 100 meters, in line with the IEEE 802.3bt standard.
Q: Can the NETWAY1BTS operate in an unheated outdoor enclosure in winter?
A: Yes. The operating temperature range is -30°C to 55°C, which covers most cold-climate unheated enclosures and parking structures. Storage temperature is rated to -30°C to 85°C.
Q: Does the NETWAY1BTS pass Gigabit data speeds?
A: Yes. The data path supports 10/100/1000 Mbps, so high-bitrate video from 4K or multi-sensor cameras is not bottlenecked by the injector.
Q: What AC input voltages are supported?
A: The NETWAY1BTS accepts 115VAC (1.2A) or 230VAC (0.75A), making it usable on both North American and international mains supplies.
The spec that makes the NETWAY1BTS worth specifying — rather than just grabbing any 802.3bt injector — is the dry contact shutdown input. In practice, that means you can wire this directly to an alarm panel output or a relay on an access control system and cut power to a connected camera or device on a contact closure, without touching the switch or sending an SNMP command. I see this most often on perimeter sites where physical-security logic needs to override network-layer control.
Technical Highlights:
- 90W 802.3bt Output: Full Class 8 power budget covers PTZ cameras with integrated IR and heaters, multi-sensor panoramic units, and access control panels that exceed the 30W PoE+ ceiling — without a secondary local power supply at the device.
- -30°C Cold-Start Rating: Most commodity injectors are rated to 0°C or -10°C. The NETWAY1BTS's -30°C floor means it initializes reliably in unheated garage enclosures and exterior junction boxes during hard winters — a real distinction in northern climates.
- Gigabit Data Path: 10/100/1000 Mbps pass-through keeps the data link at full speed, so a 4K multi-sensor camera on a 90W draw doesn't also get its bitrate choked by a 100Mbps bottleneck in the injector.
Deployment Considerations:
- At 1.2A draw on 115VAC, plan your circuit breaker budget carefully if you're stacking several NETWAY1BTS units in the same enclosure — each one is a meaningful load on a 15A or 20A branch circuit.
- The dry contact input is the distinguishing feature, but it requires an external dry contact source (alarm panel relay, key-switch, building automation output). If your deployment has no contact closure source, you're paying for a capability you won't use — evaluate a standard 802.3bt injector instead.
The NETWAY1BTS is the right call for a single high-draw PTZ or multi-sensor camera at a perimeter post or parking structure entrance where alarm-panel-triggered camera shutdown is a physical security requirement — not a general-purpose injector for every port on a multi-camera install.
