Camden CV-WTX2H-H26SE Two-Channel Wiegand Proximity Reader
The Camden CV-WTX2H-H26SE is a two-channel Wiegand proximity reader engineered for access control systems requiring HID 125kHz credential support with legacy and modern panel compatibility. Operating at 16VDC, the reader outputs dual Wiegand channels, allowing a single reader to service two egress paths—primary entry and emergency exit, for example—without consuming additional panel ports or requiring field rewiring. The dual-channel architecture is particularly valuable in retrofit scenarios where panel resources are constrained or when you need to isolate reader outputs for separate alarm inputs and relay triggers.
Key Features
- Dual Wiegand Output Channels: Two independent Wiegand streams from a single reader head. Reduces panel port consumption and wiring complexity in multi-door installations.
- HID 125kHz Proximity Support: Reads 37-bit HID proximity cards and key fobs (iCLASS SE compatible). No credential format conversion required for existing HID deployments.
- Wiegand + OSDP Protocols: Native Wiegand output (backward-compatible with door controllers built since the 1990s) and OSDP support for bidirectional communication, tamper reporting, and future firmware updates without reader replacement.
- 16VDC Power, Compact Draw: 35mA typical, 75mA peak. Direct 16VDC supply reduces step-down transformer overhead; works with standard access control power supplies rated 2–4A across multiple readers.
- IP67 Exterior Rating: Weatherproof enclosure withstands direct water spray, salt-fog environments, and dust ingress. Suitable for covered outdoor mullions, vestibules, and loading-dock mounting without additional polycarbonate shrouds.
- Wall and Rack Mount Flexibility: Single-gang wall plate or DIN-rail mounting in electrical panels. Standard 24 AWG multi-conductor shielded cabling interface.
- 8-Inch Read Range: Proximity activation distance optimized for card-swipe workflows and key-fob tap authentication. Metal-frame proximity and conduit routing will reduce range; field validation at final installation recommended.
- 3-Year Manufacturer Warranty: Factory warranty covers defects in materials and workmanship under normal operating conditions.
The CV-WTX2H-H26SE is purpose-built for retrofit and expansion scenarios where existing HID credential stock must be preserved and space or electrical panel density is a constraint. Unlike single-channel proximity readers that consume one panel input per door, the dual-channel design consolidates two access paths onto one reader head and two panel outputs, simplifying wiring and reducing material costs on larger projects. The Wiegand protocol is the de facto standard in access control; nearly every door controller from Honeywell Pro series, Linear, Salto, and IP-based controllers with Wiegand gateways will interface directly without protocol conversion.
OSDP support future-proofs the reader against aging Wiegand installations. OSDP provides bidirectional signaling—the panel can query reader health, detect tampering or forced removal, and push configuration updates remotely. This is especially valuable in multi-site deployments where centralized monitoring and audit trails are required. Wiegand remains the fallback protocol; OSDP is optional and only activated if your controller supports it.
Operating range of -31°F to 150°F and humidity tolerance of 0–90% without condensation make the unit suitable for climate-controlled interiors, cooled vestibules, and covered outdoor areas. IP67 rating means the reader survives pressure-wash cleaning and salt-spray exposure typical of parking structures, marina facilities, and food-processing plants. Mounting flexibility—wall-mounted single-gang or DIN-rail in a panel—reduces installation labor and site-specific engineering. Peak current draw of 75mA is manageable on standard 16VDC access control supplies; verify available headroom if daisy-chaining more than four readers on a single supply circuit.
The reader operates on multi-conductor shielded cabling (24 AWG recommended for runs over 100 feet). Long cable runs in noisy electrical environments (near motor drives, LED fixtures, or VFD systems) can introduce Wiegand signal corruption; foil shield and twisted-pair layout are essential to maintain signal integrity. Proximity to metal frames, conduit, or large ferrous equipment will reduce read range below the rated 8 inches—always validate final placement in situ before closing walls or sealing conduit. If your existing infrastructure uses ABA magnetic stripe, Prox/Wiegand dual-format readers, or other credential schemes outside HID 125kHz, this reader will not decode those credentials; credential format verification is a prerequisite for order confirmation.

We've deployed the Camden CV-WTX2H-H26SE across multi-tenant office parks, warehouse retrofits, and facilities where panel real estate is already spoken for. The dual-channel Wiegand output is the core differentiator—in retrofit projects, you often inherit a door controller with only two or three available input channels, and a single-channel reader means you lose a port for an emergency exit or secondary credential zone. The CV-WTX2H-H26SE eliminates that bottleneck: one reader, two independent Wiegand streams, and you've carved out two full access paths without panel replacement or expensive I/O module upgrades. On a 40-door expansion, we've seen integrators save 15–20 hours of engineering rework simply by spec'ing dual-channel readers instead of two single-channel units and wiring harnesses.
The Wiegand protocol alone is a huge advantage for backward compatibility. We've been installing access control systems for 20+ years, and Wiegand is the one constant—it predates modern IP-based controllers by two decades, and the format is so simple and deterministic that even budget-tier door controllers and DIY setups speak it fluently. The addition of OSDP is forward-looking: if a customer wants to migrate toward managed, centralized access monitoring (Salto, Genetec, or cloud-hosted platforms), OSDP gives them a path without swapping out readers. It's a smart hedge.
On the downside, 8-inch read range is real estate you have to respect. It's adequate for typical card-swipe authentication or key-fob tap scenarios, but it's not a long-range reader. If your site has poorly positioned mullions, narrow entryways, or users who hang badges on lanyards rather than swiping, you'll get complaints. We've had projects where proximity to steel door frames and stainless mounting plates reduced effective range to 5–6 inches; in one case, a customer's RFID floor mat in a secure corridor actually shielded the reader field. Field validation is non-negotiable. Also: the 16VDC supply assumption means you need a dedicated 16VDC access control supply circuit; many newer IP-based controllers use 12VDC or PoE, so verify your power budget before committing.
Technical Highlights:
- Dual Independent Wiegand Channels: Each channel outputs full 26-bit Wiegand format (facility code + cardholder ID). Allows two separate egress decisions from one reader—typical deployment is primary access on Channel 1, emergency exit release on Channel 2, both fed into separate panel inputs or relay circuits. Eliminates need for external Wiegand splitter modules and consolidates cabling.
- HID 37-Bit Credential Support: Reads standard HID proximity cards (iCLASS SE compatible). The 37-bit format includes a 16-bit facility code and 19-bit cardholder ID, sufficient for deployments up to 65,000 unique cardholders per facility code. Not compatible with older 26-bit HID format or other OEM proximity schemes; verify existing credential stock before installation.
- OSDP Fallback Mode: Supports Open Supervised Device Protocol for controllers that demand tamper alerts, remote diagnostics, and bidirectional signaling. If OSDP is not supported, the reader reverts to standard Wiegand output without loss of functionality. No firmware burn or jumper reconfiguration needed.
- 35mA Typical, 75mA Peak at 16VDC: Efficient power budget allows 3–4 readers per standard 2A access control supply circuit. Peak inrush occurs on power-up or reader reset; verify supply voltage stability under peak load to prevent nuisance card read failures on low-voltage installations.
- IP67 and Temperature Range -31°F to 150°F: Rated for salt-fog and pressure-wash environments without protective shrouds. Operating temperature range accommodates unconditioned vestibules, loading docks, and covered outdoor areas. Humidity tolerance (0–90% non-condensing) prevents internal corrosion on metal contacts even in humid climates.
Deployment Considerations:
- Read range is 8 inches max under lab conditions; metal frames, conduit, and proximity to large ferrous equipment (HVAC ducts, electrical panels, server racks) will degrade range to 5–6 inches. Always field-validate final placement with actual credential stock before sealing mounting hardware.
- Wiegand signaling is susceptible to EMI in noisy electrical environments (motor drives, variable-frequency drives, LED lighting systems). Use foil-shielded, twisted-pair 24 AWG cable for runs over 50 feet; avoid running card reader wiring parallel to power distribution or HVAC control cables for distances over 10 feet.
- Requires 16VDC dedicated supply circuit. If your site uses 12VDC or PoE-based door controllers, you will need a separate 16VDC power injector or supply module; this adds cost and complexity to retrofit projects. Verify power budget before design freeze.
- Dual-channel output means each channel must be independently configured in your panel—two separate input ports, two separate access control rules, two separate relay mappings (if applicable). Single-channel readers require less panel programming; the flexibility of dual-channel comes with slightly higher configuration overhead.
- The reader does not encode, decrypt, or validate card data; it passes raw Wiegand to the panel. If your credentials are encrypted or facility-code authenticated at the card level, the panel or VMS is responsible for validation. The reader is a dumb sensor in that regard, which simplifies troubleshooting but also means credential cloning can occur if access control policies are not enforced upstream.
The CV-WTX2H-H26SE is the right choice for integrators and facility managers retrofitting HID-based access control where panel real estate is constrained or where two independent egress paths must be serviced by a single reader head. If you're expanding a legacy Wiegand system, this reader adds future-proof OSDP capability without forcing a migration to IP-based credentials.
