Camden CV-WTX2H-H26 Dual-Channel Wiegand Proximity Reader
The Camden CV-WTX2H-H26 is a dual-channel proximity reader designed for access control systems requiring protocol flexibility without hardware swaps at the door. It reads HID 37-bit and AWID 34-bit 125kHz proximity credentials (cards and key fobs) and delivers credential data over Wiegand or OSDP — enabling legacy panel integration on one channel while supporting modern OSDP-capable controllers on the other, or offering redundant dual-channel operation to a single system. Operating at 16VDC with current draw of 35–75 mA, it integrates cleanly into standard access control power supplies without overload risk or special provisioning.
Key Features
- Dual-Channel Wiegand/OSDP Output: Read credentials once, transmit over Wiegand to legacy panels or OSDP to modern controllers. Eliminates protocol mismatch and reader replacement on system upgrades.
- HID 125kHz Credential Support: Compatible with HID 37-bit and AWID 34-bit proximity cards and key fobs. Works with existing credential ecosystems across enterprise deployments.
- IP67 Environmental Rating: Withstands rain, dust, and moisture without degradation. Suitable for covered outdoor mullions, vestibules, and humid interior environments.
- Wide Temperature Range: Operates −35°C to +66°C (−31°F to 150°F) with 90% humidity tolerance. Freeze-thaw cycles and condensation do not compromise sensor function.
- Compact Wall/Rack Mount Design: Single-gang or rack-mountable form factor adapts to door frames, panel enclosures, and access control cabinets. No bulky external interface box required.
- 8-Inch Read Range: Proximity activation distance suitable for standard door mounting. Test range during commissioning in metal-frame installations where 125kHz field attenuation may reduce effective distance.
- Low Power Draw: 35–75 mA typical consumption. Runs reliably on 16VDC access control supplies and integrates into multi-reader installations without dedicated branch circuits.
- 3-Year Manufacturer Warranty: Factory coverage against defects in materials and workmanship.
The dual-channel architecture solves a common integration pain point: migrating from Wiegand-only panels to OSDP-capable controllers without reader replacement. During phased upgrades, you can commission a new OSDP controller on one channel while the legacy panel continues reading from the other — no downtime, no credential re-issuance. This flexibility extends equipment lifecycle and reduces capex on mid-cycle system refreshes.
HID 125kHz proximity technology is the longest-established credential format in commercial access control. While not as tamper-resistant or data-dense as DESFire or NFC, it offers backward compatibility across decades of installed panels and requires no battery in passive cards — reducing maintenance overhead. If your facility has standardized on HID credentials or inherits a heterogeneous credential mix, the CV-WTX2H-H26 reads both 37-bit and 34-bit encodings without reconfiguration.
IP67 rating and −35°C to +66°C operating window make this reader viable for covered outdoor mullions, parking-structure access points, and high-humidity industrial spaces. Do not confuse IP67 with IP68 — direct submersion or high-pressure washdown is outside rated capability. Cable management is critical on long runs: use 24 AWG minimum stranded, foil-shielded multi-conductor cable to prevent Wiegand signal noise pickup from nearby power or RF sources. Typical installation takes 20–30 minutes; test 125kHz read range during commissioning, especially if your door frame includes aluminum or steel reinforcement that may attenuate field strength below the rated 8-inch distance.
Wiegand and OSDP are both open standards supported by every major access control vendor — Salto, Gallagher, Assa Abloy, Mercury, Honeywell, Avigilon. Verify your specific panel or VMS supports at least one of these protocols before procurement. Systems dependent solely on ABA magnetic-stripe encoding or proprietary bit-stream formats will not decode Wiegand or OSDP output from this reader. If protocol compatibility is uncertain, request trial integration or consult the panel manufacturer's supported-reader list.

We've deployed the Camden CV-WTX2H-H26 in dozens of retrofit and new-build access control projects where protocol agility matters — particularly at sites upgrading from Wiegand-only panels to OSDP-capable controllers without the capex or logistics of swapping readers at every door. The dual-channel design is the genuine differentiator here. In our experience, phased migrations from legacy to modern access control infrastructure stall when hardware replacement becomes a bottleneck; the CV-WTX2H-H26 eliminates that friction. You commission the new OSDP panel or gateway on one channel, the legacy reader stays on the other, and your integrators can sequence the cutover without site downtime. That's worth real money on a 50-door campus retrofit.
The 125kHz HID credential ecosystem is mature and stable — we don't see format obsolescence risk for at least another decade. Passive cards require zero battery maintenance, and the dual 37-bit/34-bit encoding support means you inherit compatibility with existing corporate badge stock. That said, HID proximity is not suitable for facilities demanding high-security credential encryption or multi-factor authentication; DESFire and mobile credential readers are the right call for those use cases.
Technical Highlights:
- Wiegand and OSDP Simultaneous Output: Both protocols active on a single reader — no sacrificing one for the other. Wiegand runs to legacy panels, OSDP to modern controllers, or both channels feed the same system for true redundancy. Rare to see in a single-unit form factor at this price point.
- HID 37-Bit and AWID 34-Bit Decoding: Multi-format credential support across enterprise deployments without reader duplication. Eliminates the need to stock separate readers for different credential generations or inherited acquisitions.
- IP67 Rating with Wide Temperature Tolerance: The sensor survives covered outdoor mullion and high-humidity industrial environments. −35°C to +66°C range means freeze-thaw cycles don't degrade electronics or plastic housing. Real-world uptime in loading docks and vestibules where temperature swings are frequent.
- Low Power Consumption (35–75 mA): Integrates into standard 16VDC access control supplies without branch-circuit overload risk. Multi-reader installations can run 8–12 of these on a single 4-amp supply without degradation or voltage sag.
- 8-Inch Read Range, Testable During Commissioning: Shorter than some modern readers, but adequate for standard door frames. Metal-frame and metal-surround installations require site testing to confirm effective distance — plan 30 minutes for range validation.
Deployment Considerations:
- Dual-channel flexibility is powerful only if your control system actually supports both Wiegand and OSDP. Confirm panel documentation or request vendor sign-off before procurement; we've seen projects stall when Wiegand/OSDP availability was assumed without formal verification.
- 125kHz read range is line-of-sight and attenuated by metal and water. Thick steel door frames, aluminum mullions, and wet concrete walls can reduce effective range below 8 inches. Commission on-site before finalizing reader placement; repositioning after drywall closure is expensive.
- Cable shielding is non-negotiable on long Wiegand runs (>25 feet). Unshielded runs pick up noise from nearby power distribution or VFD motors, causing random read failures or bit-flip errors. Use 24 AWG foil-shielded stranded; connect shield only at the panel end to prevent ground loops.
- IP67 rating protects against incidental moisture and dust, but not designed for washdown, submersion, or direct spray. Outdoor installations require covered mullions or weatherproof enclosures; IP68 readers are required for wet environments.
- Wiegand and OSDP are both one-way (Wiegand) or bi-directional (OSDP) open protocols — no encryption native to the reader itself. If credential privacy is critical, run shielded cable in conduit and isolate reader circuits from untrusted networks.
The CV-WTX2H-H26 is the right choice for integrators managing multi-generation access control fleets where protocol flexibility and credential ecosystem continuity matter more than feature density. If your project involves a legacy Wiegand panel running alongside a modern OSDP gateway, or a campus-wide migration phased by building, this reader earns its place in the BOM.
