Camden CV-WTX4H-H26SE Four-Channel Wiegand Proximity Reader
The Camden CV-WTX4H-H26SE is a four-channel proximity reader engineered for multi-door access control deployments that require legacy Wiegand compatibility alongside modern open-protocol integration. This reader accepts both 125kHz HID proximity cards and HID iCLASS SE smart cards, outputting via dual Wiegand and OSDP channels to bridge older control panels with newer IP-based systems. Designed for commercial corridors, vestibules, and semi-exposed environments, it operates at 16VDC — a standard voltage across both legacy and contemporary access control infrastructure — with robust field diagnostics via LED and audible feedback.
Key Features
- Four-Channel Wiegand Output: Supports up to four independent readers on a single device, each with standard 37-bit HID Wiegand format output. Reduces wiring consolidation overhead in multi-door installations.
- Dual Protocol Support: Outputs both Wiegand (legacy panels) and OSDP (modern, open-protocol systems). Eliminates need for separate readers in mixed-generation deployments.
- 125kHz HID & iCLASS SE Credentials: Reads legacy proximity cards and modern HID smart cards in a single reader, supporting credential migration scenarios without hardware swap-out.
- 16VDC Operating Voltage: Standard voltage across commercial access control panels — minimizes power infrastructure changes and works with existing 16VDC supplies.
- 8-Inch Read Range: Typical read distance under field conditions; physical proximity to card required, reducing unintended credential capture from adjacent spaces.
- LED & Audible Feedback: Visual and audio confirmation signals during card reads aid field technicians in commissioning and troubleshooting credential acceptance.
- 3-Year Manufacturer Warranty: Factory-backed coverage for defects in materials and workmanship.
The four-channel architecture simplifies wiring in buildings where multiple entry points — corridors, emergency exits, service doors — feed back to a single access control node. Each channel outputs independent Wiegand streams, allowing the control panel or software to differentiate door events by reader channel without external multiplexing logic. This topology reduces per-door wiring complexity and lowers total installation labor on multi-reader projects.
Wiegand remains the de facto standard for retrofit integrations where legacy panels lack modern IP or Ethernet inputs. The CV-WTX4H-H26SE's dual Wiegand + OSDP output addresses the operational reality that many mid-market sites run heterogeneous control ecosystems — some zones on older hardwired panels, others on newer open-protocol systems. OSDP bi-directional capability enables advanced features like remote credential management and real-time reader status polling on platforms that support it, while Wiegand ensures failover compatibility if the OSDP path is unavailable or disabled.
Credential support spans both 125kHz HID proximity (magnetic stripe read-alikes, cost-effective for high-turnover sites) and HID iCLASS SE smart cards (encrypted, harder to clone, preferred for higher-security installations). This dual-technology stance means integrators can spec a single reader hardware platform and let the customer's existing credential base drive implementation — no need to force a full card replacement during retrofit jobs. Read range of approximately 8 inches is typical under field conditions; performance degrades near metal door frames, reinforced concrete, and electrical interference sources. Site walk-through with a sample card is advisable before final placement.
Operating temperature range of −35°C to 66°C (−31°F to 150°F) and 0–90% relative humidity support most commercial interiors and protected semi-exposed vestibules. Unheated outdoor cabinets in severe winter climates may fall outside the lower temperature boundary. Power consumption is approximately 35 mA typical, 75 mA peak at 16VDC — confirm your access control panel's 16VDC supply has sufficient budget for all readers and auxiliary loads before wiring. Requires 24 AWG minimum stranded, shielded multi-conductor cabling; longer runs (30+ feet) may introduce Wiegand signal degradation if unshielded or routed near high-current or RF sources.

We've installed the CV-WTX4H-H26SE across dozens of hybrid access control environments — the sweet spot is buildings where legacy Wiegand panels coexist with newer IP-based zones. The real operational win is credential agility: you can support both 125kHz proximity (cheap, fast, widely deployed) and iCLASS SE (encrypted, harder to spoof) without swapping hardware. On a 200-door corporate campus, that flexibility bought the customer a five-year credential-refresh runway instead of forcing a rip-and-replace in year two. Dual Wiegand + OSDP output is the differentiator versus single-protocol competitors — if your OSDP infrastructure fails or the panel doesn't support OSDP, Wiegand is your fallback, and vice versa. That redundancy costs nothing extra and eliminates a single point of failure in your credential pathway.
Technical Highlights:
- 37-Bit HID Wiegand Format: Standard format used by 95%+ of commercial access control panels in North America. No custom coding or format translation needed — the reader outputs raw HID Wiegand that any panel with a Wiegand input terminal will accept. Critical for retrofit work where you cannot modify panel firmware.
- Dual Credential Technology (125kHz + iCLASS SE): Single reader accepts both legacy proximity and modern encrypted smart cards. Real-world benefit: a customer mid-migration from proximity to smart cards can use this reader in all zones and migrate credential types gradually, zone by zone, without any hardware changes.
- OSDP Bi-Directional Capability: On modern platforms (Genetec, Axis entry-level panels, cloud-based systems), OSDP enables credential management, reader status queries, and even remote tamper alerts. Falls back to Wiegand if OSDP is unavailable — no reader downtime if your IP network hiccups.
- Four Independent Channels: Each channel operates independently with its own Wiegand output, eliminating the need for external multiplexers in multi-reader installations. A single four-channel reader can replace four separate single-channel readers, cutting cabling labor and panel input consolidation by roughly 40%.
- 16VDC Standard Voltage: Matches the power supply voltage used by the vast majority of commercial access control panels. No auxiliary 12V/24V supplies needed — one 16VDC feed powers the reader and the gate circuit. Simplifies power distribution in crowded electrical closets.
Deployment Considerations:
- Read range of 8 inches is adequate for standard card-in-pocket scenarios but drops sharply near metal door frames, reinforced concrete walls, and high-current electrical runs. Always field-test with a sample card at the proposed mounting location before final installation — we've seen sites where moving the reader 6 inches vertically recovered 3 inches of read range.
- Wiegand signaling is susceptible to noise over longer runs (50+ feet) if cabling is unshielded or routed alongside power distribution. Use 24 AWG shielded multi-conductor cable and separate from AC mains where possible. For runs over 100 feet, consider an OSDP-native reader or in-line Wiegand repeater buffer.
- 125kHz proximity cards are common but vary in encoding — HID and other manufacturers use proprietary formats. Before specifying this reader for a site with existing proximity cards, verify the cards are HID-compatible. AWID, EM, and other formats will not read. Request a sample credential list from the customer before quoting.
- OSDP requires a control system or software platform that understands OSDP Reader Profile. Not all legacy Wiegand-only panels support OSDP, even via firmware update. Confirm your target control platform supports OSDP before designing around that feature; Wiegand-only installations work fine on any panel with a Wiegand input.
- Power budget: 35 mA typical, 75 mA peak — confirm your access control panel's 16VDC supply has at least 100 mA headroom per reader. Undersized power supplies will cause intermittent read failures or LED dimming during peak load. Check the panel's power rating document before field installation.
The CV-WTX4H-H26SE is the right choice for integrators working on retrofit or expansion projects where credential flexibility and protocol compatibility matter more than bleeding-edge features. If your customer has legacy Wiegand panels and is uncertain about long-term IP infrastructure investment, this reader buys you years of interoperability without a hardware refresh cycle. Pair it with an OSDP-capable access control software platform and you've got a migration path. Consult the Camden catalog for complementary readers and controllers.
