SDC WRC-R2 Two-Channel Wireless Receiver
Overview
The SDC WRC-R2 is a two-channel wireless receiver engineered for distributed access control systems where wireless credential readers and networked access points must operate under centralized management. Unlike hardwired reader infrastructure, the WRC-R2 bridges HID-compatible wireless readers to your TCP/IP networked access control system, making it the right choice for retrofit installations, warehouse expansions, or any facility where running new conduit is cost-prohibitive or impractical. Operating on 12VDC, it consolidates wireless signal reception and protocol translation in a single compact controller.
Key Features
- Two independent channels: Each channel operates as a separate reader input, so you can deploy two distinct wireless credential readers on one WRC-R2 unit. This halves the number of controllers you need to manage in a multi-door system and simplifies wiring to your access control panel.
- Support for up to 250,000 user credentials: The WRC-R2 handles enterprise-scale credential databases without bottleneck. Typical multi-door installations (retail, warehouse, or corporate) rarely exceed 10,000–50,000 active users; this headroom means you won't outgrow the unit as your workforce scales.
- OSDP and TCP/IP communication: OSDP (Open Supervised Device Protocol) is the modern standard for reader-to-controller dialogue and delivers encryption and tamper reporting that older Wiegand protocols cannot. TCP/IP connectivity means the WRC-R2 integrates into any standards-based access control system or VMS platform without proprietary gateway hardware.
- HID credential compatibility: The receiver works with HID card and fob ecosystems. If your organization already deploys HID readers elsewhere, this receiver eliminates vendor lock-in and simplifies procurement — you're not forced to buy a complete new reader family.
- 12VDC power input: A low-voltage, single supply voltage simplifies installation and reduces risk of mains-voltage exposure. Standard 12VDC supplies are commodity items and available in redundant or backup configurations if your site requires it.
- Supports up to 4 doors: While two-channel in receiver function, the WRC-R2 architecture allows control of up to four doors. This flexibility accommodates installations where two wireless readers control separate door pairs — common in warehouse loading docks or secure entry vestibules.
Integration and Compatibility
The WRC-R2 (often searched as WRC R2) is built for access control integrators working with enterprise and institutional deployments. Its OSDP interface and TCP/IP backbone mean compatibility with any access control management platform that speaks these standards — Milestone XProtect, Genetec, Honeywell, and vendor-agnostic control panels. Wireless credential readers and the WRC-R2 form a distributed reader pair; position the receiver near an existing network infrastructure point and eliminate trenching runs across parking lots or production floors.
Retrofit projects benefit most from this topology. If you're adding a new secure entrance to an existing facility and the control panel is 300 feet away, the WRC-R2 receiver can sit near the new door, receive wireless signals from a paired reader, and send OSDP commands back to your central panel over standard network cable — no need for conduit runs or relay cabinets.
Deployment Considerations
Range and line-of-sight matter. Wireless readers and the WRC-R2 must maintain clear RF paths; metal framing, water-filled walls, and dense shelving reduce effective range. Conduct a site survey before ordering. The 12VDC supply should be regulated and protected by fusing at the power entry point. If the WRC-R2 is located in a secure cabinet away from the entry point, run power through a conduit or cable tray to avoid tampering.
Frequently Asked Questions
Q: Does the WRC-R2 work with non-HID wireless readers?
A: No. The receiver is designed for HID-compatible credential readers. Verify reader compatibility before purchase.
Q: Can I connect the WRC-R2 directly to a TCP/IP network without an intermediate control panel?
A: Yes. The WRC-R2 communicates via TCP/IP and OSDP, so it can integrate with any management platform or access control system that supports those protocols.
Q: What is the wireless range between a credential reader and the WRC-R2?
A: Range depends on the reader model and site conditions. Consult the paired reader's documentation and conduct a site survey for the specific installation.
Q: Can I operate the WRC-R2 on a backup battery or UPS?
A: Yes. Supply the WRC-R2 with 12VDC from a UPS or backup battery system using appropriate fusing and voltage regulation.
Q: Is the WRC-R2 suitable for outdoor installations?
A: The receiver itself is a controller and should be housed indoors or in a weatherproof enclosure. Wireless readers deployed outdoors must be rated for the environment; the WRC-R2 does not add environmental hardening.
Q: What does "up to 4 doors" mean when the unit is a two-channel receiver?
A: The WRC-R2 has two wireless reader channels; each channel can control readers covering multiple doors depending on your system's lock control architecture. Consult your integrator for the specific door configuration.

The WRC-R2 solves a real problem in retrofit access control: you've got a central control panel hardwired to existing doors, but you need to add a new secure entrance 200 feet away, or your warehouse is expanding and running new conduit isn't feasible. The WRC-R2 receiver lets you deploy wireless HID readers and keep your central infrastructure intact. The 250,000-credential capacity means you're not trading convenience for scale — this is a genuine enterprise-class receiver, not a single-site toy.
Technical Highlights:
- Two independent channels: Each channel is a separate reader input, so you get the equivalent of two wired reader installations without doubling controller footprint. This cuts hardware cost and panel space in multi-door layouts.
- OSDP + TCP/IP dual protocol: OSDP provides tamper signaling and encrypted communication that Wiegand cannot; TCP/IP means any standards-based VMS or access control platform will recognize this device natively. No proprietary gateway required.
- 250,000 credential support: Enterprise credential databases scale into the tens of thousands on a single device. You won't hit this ceiling in typical deployments — meaningful headroom for growth without controller replacement.
Deployment Considerations:
- RF line-of-sight is critical: Wireless readers and the WRC-R2 must have clear paths. Dense metal shelving, concrete walls, and high-RF-noise environments (manufacturing floors with industrial heating, older radio systems) can degrade range. Site survey before deployment is not optional.
- 12VDC power must be protected: Use fused, regulated supply and house the controller indoors or in a locked cabinet. An unprotected power input is a physical tampering vector and a liability in high-security installations.
- HID reader ecosystem lock-in: The WRC-R2 is HID-only. If you deploy non-HID wireless readers elsewhere in your organization, you cannot mix protocols on this receiver. Plan your wireless reader standard before scaling out.
Best fit: warehouse operations, retail chains, and corporate campuses adding new secure points without infrastructure overhaul. If you're managing a multi-building campus and central conduit runs are impractical, the WRC-R2 + HID wireless readers cut your deployment timeline and cost. For single-door retrofits or small facilities, you may be over-specified; consult your integrator on whether a wired reader is simpler. For high-security government or financial sites, confirm OSDP tamper reporting and credential-audit logging align with your compliance framework — OSDP is capable, but configuration matters.
