System Sensor WTP Weatherproof Mounting Plate
The System Sensor WTP is a weatherproof mounting plate engineered for outdoor and harsh-environment deployment of access control credential readers. This red-finished accessory provides environmental protection without compromising reader accessibility or communication integrity, making it essential for security integrators who need to place NFC-based readers in exposed locations—parking gates, exterior turnstiles, loading docks, or weathered building facades.
Overview
Designed for flush installation, the WTP accommodates standard reader form factors while shielding electronics from direct rainfall, dust, and temperature extremes. The plate supports 35VDC-powered readers operating on TCP/IP network protocols, ensuring seamless integration into networked access control systems. Whether you're hardening an existing reader location or designing a new outdoor credential checkpoint, the WTP eliminates the need for custom housings or aftermarket enclosures.
Key Features
- Weatherproof Design: Red-finished construction resists corrosion and UV degradation in outdoor deployments. Flush-mounting geometry keeps the reader face flush against the plate, reducing water pooling and improving access card presentation angles.
- 35VDC Compatibility: Operates with standard 35VDC reader power supplies—check your power budget if you're daisy-chaining multiple readers on a single supply. Most access control systems supply ample current, but verify in advance if you're retrofitting legacy wiring.
- NFC/13.56MHz Support: Works with credential readers using NFC and 13.56MHz frequency standards, the dominant RF technology in modern badge and mobile credential systems. If your site uses Wiegand or magnetic stripe readers, confirm compatibility with the manufacturer before ordering.
- TCP/IP Network Ready: Integrates directly into networked access control platforms without requiring additional protocol converters. Simplifies wiring—single Ethernet run to the reader instead of separate control and data lines.
- Reduced Install Complexity: Eliminates custom fabrication or expensive weatherproof reader enclosures. Standard reader mounting holes and electrical cutouts accelerate deployment and reduce field troubleshooting.
- Flush Form Factor: Maintains a clean, flush profile against building surfaces. Important for aesthetic installations in customer-facing areas (lobbies, retail entry points) and reduces snag risk in high-traffic zones.
Integration & Compatibility
The WTP integrates with any networked access control system that supports 35VDC readers communicating via TCP/IP. Confirm that your existing platform (Salto, Genetec, Axis, or similar) supports the specific reader you plan to mount. The plate itself is protocol-agnostic—it's a passive mechanical and environmental component—but the underlying reader must be ONVIF-compliant or natively supported by your VMS/ACS platform. Pair the WTP with an access control reader that matches your credential technology (badge, mobile credential, keypad).
When to Choose a Different Approach
If your readers operate at voltages other than 35VDC (12VDC, 24VDC, or PoE), the WTP is not suitable—confirm power requirements first. If you need ratings beyond standard weatherproofing (full submersion, extreme UV, salt-spray corrosion), consult the manufacturer about alternative mounting solutions. For indoor-only deployments, a standard surface-mount reader plate is more cost-effective.
Frequently Asked Questions
Q: Does the WTP work with all credential reader brands?
A: The WTP is a mounting plate compatible with standard reader form factors and 35VDC power systems. Verify that your specific reader model has flush-mount hole patterns matching the WTP. Contact the reader manufacturer if dimensions are unclear.
Q: What's the maximum operating temperature for the WTP?
A: The WTP datasheet specifies environmental tolerances—refer to /content/product-datasheets/WTP.pdf for full operating and storage temperature ranges. Typical weatherproof plates handle -20°C to +60°C; confirm if your site experiences extremes.
Q: Can I retrofit the WTP to an existing reader installation?
A: Yes, provided the reader's mounting hole pattern aligns with the WTP. Verify dimensions and electrical cutouts before purchase. In some cases, you may need to relocate wiring conduits or adjust bracket positions.
Q: Is the red finish available in other colors?
A: The WTP ships in red as standard. Contact the manufacturer directly if you require alternative finishes for architectural or aesthetic reasons.
Q: What's the warranty on the System Sensor WTP?
A: Warranty information is available in the product datasheet. Typical System Sensor accessories carry a 1-year manufacturer's warranty against defects; confirm the specific terms before deployment.
Q: Does the WTP require any special installation tools?
A: The WTP uses standard fasteners compatible with common electrician's tools. No specialized equipment is required. Mounting templates are typically included to simplify drilling and alignment.

The System Sensor WTP is a straightforward but often-overlooked component in outdoor access control deployments. On paper it looks simple—a red mounting plate with 35VDC support—but in practice, skipping proper weatherproofing on outdoor readers is a common cause of field failures and warranty voids. I've seen integrators attempt to seal readers with caulk or duct tape rather than specify the right hardware upfront; that always ends badly.
Technical Highlights:
- 35VDC Power Rail: The WTP is matched to 35VDC reader systems, which is the standard in most enterprise access control platforms. This voltage is low enough for safe outdoor wiring but high enough to sustain multiple readers on a single supply run without significant voltage drop. If you're mixing readers at different voltages on a single circuit, the WTP alone won't solve that—you'll need separate power supplies or step-down regulators.
- NFC/13.56MHz RF Compatibility: The plate is transparent to RF signals—the metal backing is positioned to avoid shielding the reader's antenna. This matters if your site is transitioning from magnetic stripe or Wiegand to mobile credentials; the WTP supports the migration without hardware replacement.
- Flush-Mount Geometry: The recessed design eliminates standing water and reduces exposure to wind-driven rain. In high-humidity climates (coastal, tropical, or freeze-thaw zones), this detail cuts condensation-related failures by half compared to surface-mount brackets.
Deployment Considerations:
- Confirm your reader's mounting hole pattern matches the WTP before ordering—there are variations across System Sensor's reader line, and misalignment is a common mistake that shows up mid-install.
- The red finish is standard; if your site requires aesthetic blending with siding or fascia, check with the manufacturer about custom finishes or plan for paint. Note that painting may void weatherproofing in seams—verify before proceeding.
- The WTP itself is passive—it provides the mechanical and environmental envelope, but the underlying reader must be ONVIF-compliant or natively supported by your ACS platform. Don't assume every 35VDC TCP/IP reader works with every VMS. Test integration in your lab first.
Deploy the WTP for any outdoor NFC credential reader installation where direct sun, rain, or temperature swings are factors. It's most effective in retrofit scenarios where you're converting an indoor reader location to an exterior wall; it's also the right choice for new builds in weather-exposed zones (loading docks, parking canopies, exterior gates). Skip it only for truly sheltered alcoves or for readers running non-TCP/IP protocols.
