Altronix WP4 NEMA 4/4X IP66 Stainless Steel Enclosure
The Altronix WP4 is a NEMA 4/4X and IP66-rated stainless steel enclosure engineered for outdoor and corrosive-environment security deployments. At 9.32" H × 7.32" W × 4.92" D, the WP4 provides compact, robust protection for network and power distribution equipment in sites where weather, salt spray, or industrial contamination would degrade standard carbon steel or plastic housings. This is the enclosure you choose when you need equipment to survive coastal installations, industrial perimeters, or remote surveillance sites without premature corrosion.
Key Features
- NEMA 4/4X and IP66 Environmental Rating: NEMA 4/4X means the enclosure blocks windblown dust and water spray from any direction — critical for rooftop or pole-mounted installations. IP66 carries the same message in international terms. This rating combination stops rain, hose-down spray, and blowing dust, but does not offer full submersion protection; if the enclosure will be underwater or in a regularly submerged location, you'll need IP67 or higher.
- Stainless Steel Construction: Unlike painted or powder-coated steel, stainless does not rust when exposed to salt air, industrial chemicals, or repeated moisture cycles. Service life extends dramatically — especially valuable in coastal or chemical-plant perimeters where you want to avoid replacement every 3–5 years.
- Five Integrated Network Ports: Provides direct connectivity for up to five network devices or switches without external cable trays or junction blocks. Simplifies cabling and reduces single points of failure in remote surveillance or access-control nodes.
- Five Output Terminals for Power or Signal Distribution: Accommodates multiple circuit connections within a single compact footprint. Reduces clutter on equipment racks or outdoor pole mounts and consolidates wiring terminations in one secure location.
- Compact Form Factor: At just under 9.5" tall and 7.5" wide, the WP4 fits into space-constrained installations where larger enclosures would require structural modifications or additional mounting hardware. Ideal for pole-mounted or wall-mounted power and network consolidation at remote camera sites.
- Lifetime Limited Warranty: Altronix backs the WP4 with a lifetime limited warranty, reflecting confidence in stainless construction and reducing the risk of unexpected replacement costs in the field.
Deployment Context
The WP4 excels in outdoor surveillance infrastructure where equipment protection and longevity outweigh the slightly higher initial cost versus standard enclosures. Typical deployments include perimeter security nodes combining power distribution and network consolidation in a single hardened package, coastal marina or port security systems where salt spray accelerates corrosion, industrial facilities with acid fumes or alkaline residue, and remote camera arrays requiring reliable equipment housing during extended maintenance intervals.
Its five network ports and five output terminals support mid-scale installations — enough to serve a small cluster of PoE cameras or access-control readers without requiring external switches or terminal blocks. The NEMA 4/4X rating ensures you won't need to re-house equipment after a single season of weather exposure in harsh environments.
Integration & Compatibility
The WP4 is a passive housing and connectivity platform — it does not include active power supplies, switches, or logic modules. Wire the five output terminals to your PoE injectors, 24VDC power supplies, or signal distribution modules. Connect network endpoints to the five integrated ports. The stainless construction and IP66 sealing work with any standard network or power equipment rated for outdoor use. Mounting hardware and cable gland specifications are documented in the manufacturer datasheet.
When to Choose a Different Model
If your deployment does not expose equipment to corrosive atmospheres or you have budget constraints, a standard powder-coated steel enclosure may suffice for short-term indoor or mild-outdoor use. If you need full submersion protection (ponds, fountains, or underwater equipment vaults), specify an IP67-rated or higher enclosure. If your installation requires more than five network ports or power terminals, consider larger enclosures in the Altronix infrastructure line.
Frequently Asked Questions
Q: Is the WP4 suitable for coastal or salt-spray environments?
A: Yes. Stainless steel resists corrosion in salt-air conditions far better than carbon steel or coated steel. The NEMA 4/4X and IP66 rating also block salt spray and windblown moisture, making the WP4 well-suited for marine and coastal perimeter deployments.
Q: Can I submerge the WP4 in water?
A: No. The NEMA 4/4X and IP66 ratings protect against rain, spray, and hose-down water, but not full submersion. If equipment must be underwater or in a regularly flooded enclosure, specify an IP67 or IP68 model.
Q: How many PoE cameras can the WP4 support?
A: The WP4 itself is a passive enclosure with five network ports and five output terminals — it does not supply power. You must connect external PoE injectors or PoE switches to the output terminals. The five network ports can connect to a PoE switch or injector, allowing you to power and network multiple cameras depending on your power supply capacity and switch specifications.
Q: What is the warranty on the WP4?
A: Altronix provides a Lifetime Limited Warranty on the WP4, covering defects in materials and workmanship for the life of the original owner.
Q: What mounting options are available?
A: The WP4 can be wall-mounted or pole-mounted. Specific mounting hardware and orientation guidelines are provided in the manufacturer datasheet.
Q: Does the WP4 come with internal power supplies or switches?
A: No. The WP4 is a protective enclosure and terminal distribution platform. You must provision external PoE injectors, DC power supplies, or network switches and connect them to the five output terminals and five network ports.

The Altronix WP4 solves a specific problem: keeping network and power infrastructure safe from weather and corrosion without overbuying enclosure size. At 9.32" tall by 7.32" wide, the WP4 is compact enough to mount on a pole or equipment rack in tight spaces, yet the stainless steel construction and IP66 sealing mean you won't be replacing it after one coastal season or industrial spray exposure. This is practical engineering for sites where environment matters.
Technical Highlights:
- Stainless Steel + NEMA 4/4X/IP66: The combination delivers salt-spray and chemical-vapor resistance that painted enclosures cannot match. Standard carbon steel rusts within 1–2 years in coastal or chemical environments; stainless extends that to 10+ years with minimal maintenance.
- Five Network Ports + Five Output Terminals: Consolidates cabling from multiple cameras, PoE switches, and DC supplies into one compact node. Reduces external cable trays, conduit runs, and labor during commissioning — especially valuable in remote surveillance clusters.
- Compact Footprint (9.32" × 7.32" × 4.92"): Fits pole-mounted, wall-mounted, or rack-edge installations where larger enclosures would require structural work or additional hardware. Every inch matters on a crowded equipment rack or a narrow utility pole.
Deployment Considerations:
- The WP4 is a passive platform — it does not include power supplies, switches, or PoE injectors. You must wire external supplies to the five output terminals. Budget for PoE injectors or 24VDC supplies depending on your camera and reader count.
- Five network ports and five terminals work for small-to-medium nodes (3–5 cameras, 1–2 access readers, or a mix). For larger perimeter clusters requiring 10+ ports, step up to a larger enclosure or add external switches outside the WP4.
- IP66 stops rain and hose-down spray; it does not provide full submersion. If equipment sits in standing water or a regularly flooded vault, choose IP67 or higher.
The WP4 is the right call for coastal, chemical-plant, or industrial perimeter surveillance where stainless construction and environmental sealing justify the cost and your footprint is modest. Skip it if you're deploying indoors with no corrosion risk or if you need significantly more than five network connections in a single node.
