ASUS ZenWiFi BD4 Outdoor WiFi 7 Mesh Router - IP65, PoE
The ASUS ZenWiFi BD4 Outdoor WiFi 7 Mesh Router is built for outdoor coverage in harsh weather, delivering dual-band speeds up to 3600 Mbps across up to 15,000 sq. ft. It suits installers and homeowners extending network range to patios, yards, or remote structures where power outlets are inconvenient, since it powers via PoE or standard AC.
Why this product
WiFi 7 with dual 2.5G PoE ports
It reaches 3600 Mbps combined across dual bands and connects via two 2.5G ports that accept PoE input, eliminating the need to run power cables to outdoor walls or poles.
IP65 weatherproofing and wide temperature range
The enclosure resists dust and water immersion, and operates reliably between −30 °C and 60 °C, making it suitable for exposed outdoor mounting year-round.
AiMesh extendable across routers
It works as a primary router or mesh node, connecting wirelessly or via wired backhaul to any compatible ASUS AiMesh router to expand coverage indoors and out.
Three SSIDs and parental control
Create separate networks for IoT devices and apply time-based parental controls, safe browsing filters, and internet schedules per device.
Multiple mounting options
Wall, pole, and flat-surface mounts ship in the box, adapting to fences, eaves, or support structures without site modifications.

- SKUASU-4265
- EAN4711387611876
- Works as primary router or AiMesh node with any compatible ASUS AiMesh router, indoors or outdoors.
- Accepts PoE input on both 2.5G ports with auto WAN detection, or runs from standard 100–240 V AC power.
- Supports IPv4, IPv6, and all WiFi standards from 802.11b through WiFi 7 (802.11be).
- IP65 rating covers water and dust immersion, but ASUS states the operating range is −30 °C to 60 °C; use in extreme climates at the edges of this range may affect longevity.
Best for
- Extending WiFi to backyards, patios, garages or remote garden structures without running power lines.
- PoE-powered outdoor installations on walls, poles, or eaves where AC outlets do not exist.
- Harsh-weather environments—dust storms, salt spray, rain, or temperature swings—thanks to IP65 enclosure and −30 to 60 °C operating range.
- Smart home networks segregated by SSID, with parental oversight and controlled internet access for family members and IoT devices.
- Installers building mesh systems across ASUS routers, combining wired and wireless backhaul in mixed indoor–outdoor layouts.
Trade-offs
- Buyers needing wired Gigabit ports; the 2.5G ports are faster but not standard 1 Gbps.
- Users in climates consistently below −30 °C or above 60 °C; it is rated only within that operating range.
- Indoor-only mesh networks; this is purpose-built for outdoor exposure and may be overkill indoors.
- Deployments requiring PoE++ (90 W) or higher power delivery; it accepts standard PoE input via its two ports.
