Hanwha SLA-T4680DW 2MP Door Jamb Lens Module
The SLA-T4680DW is a specialized lens module engineered for covert access control and entry-point surveillance where traditional visible cameras conflict with aesthetics or facility design. Built as a companion to the Hanwha XNB-6001 camera system, this 2MP pinhole module deploys directly into door frames and jambs, capturing facial detail without visual intrusion. The module combines optical discretion with genuine low-light capability—a practical combination for corridor lighting and perimeter entrances where ambient illumination is limited.
Key Features
- 2MP Resolution (1920 × 1080): Delivers sufficient pixel density for facial identification at typical doorway distances. Not suitable for wide-area coverage or distant subject recognition—this is a point-source device for entry gates and controlled access zones.
- 4.6mm Pinhole Lens: The narrow focal length and minimal form factor allow seamless integration into standard door frames without structural modification. The pinhole configuration means the module's footprint remains genuinely covert—no visible camera body or housing required.
- 0.06Lux@F2.5 Low-Light Sensitivity: This specification matters for indoor corridors and overcast entry vestibules. Standard indoor lighting (150–300 lux) will produce clean video; dimly lit stairwells or night-mode entry (below 10 lux) will require supplemental IR or exposure adjustment. Do not expect this module to perform adequately in complete darkness without active illumination.
- ±30-Degree Adjustment Range: Allows vertical and lateral aiming post-installation without hardware repositioning. Sufficient for typical door-frame angles but limits acute-angle mounting scenarios. The range is mechanical, not motorized—set once, then fixed.
- 8-Meter Cable Length: Reduces distance from lens to camera body and eliminates the need for inline extension cords at installation. For deployments where the XNB-6001 body sits more than 8 meters away, custom cabling or external conduit becomes necessary; plan infrastructure accordingly.
- White Finish: Matches standard interior door frames and jambs. Does not blend into stained wood or dark-frame installations. Verify finish compatibility with your specific door assembly before ordering.
- Hidden Security Fasteners: Mounting hardware remains concealed, maintaining the clean, non-institutional appearance essential to covert surveillance deployments.
Integration & Compatibility
The SLA-T4680DW is purpose-built for the Hanwha XNB-6001 camera system. Standalone operation is not possible—you require the parent camera body to process video, manage compression, and deliver the stream to your network or recorder. Verify your network video recorder or VMS supports the XNB-6001 before committing to this module. If you are already deploying XNB-6001 bodies elsewhere on your network, adding the SLA-T4680DW lens module integrates cleanly into your existing infrastructure.
Ideal Deployment Scenarios
Deploy the SLA-T4680DW at corporate building entrances, retail store thresholds, healthcare facility access points, and secure facility gates where security is non-negotiable but visible security infrastructure would undermine design intent or tenant acceptance. Access control integration (badge readers, magnetic locks) works alongside the module without conflict. The covert form factor is particularly valuable in heritage buildings, luxury retail environments, and professional offices where traditional dome or bullet cameras would be inappropriate.
When to Choose a Different Approach
If your entry points require wider field of view, consider a standard fixed-lens module from the Hanwha lineup with a longer focal length. If identification must occur at distances exceeding 3–5 meters, step up to higher megapixel options within the same family. If you need motorized aim adjustment or zoom capability, this module is not your solution—it is intentionally fixed and passive. If your facility is outdoor-facing or exposed to rain and dust, verify environmental ratings with Hanwha's outdoor surveillance line; the SLA-T4680DW is designed for indoor door-frame mounting.
Frequently Asked Questions
Q: Does the SLA-T4680DW work with cameras other than the XNB-6001?
A: No. This module is engineered specifically for the XNB-6001 camera system. Compatibility with other manufacturers or camera bodies is not supported.
Q: Can I extend the 8-meter cable if my camera body is farther away?
A: Standard Ethernet extension is possible with appropriate conduit and connectors, but custom cabling is outside the module's design specification. Consult the XNB-6001 documentation and your integrator before extending beyond the supplied cable length.
Q: What happens if the room is completely dark? Will the module still work?
A: The 0.06Lux rating assumes available ambient light. In zero-light conditions, you will need active infrared illumination (separate fixture) or rely on the parent camera's built-in IR (if equipped). Verify the XNB-6001 body includes IR capability for your use case.
Q: Is this module suitable for outdoor door frames?
A: No. The SLA-T4680DW is designed for interior installation. For exterior doors and vestibules, confirm IP and IK ratings with the manufacturer or consider outdoor-rated modules from the broader Hanwha catalog.
Q: How do I mount the module inside a door jamb?
A: The module uses hidden security fasteners and mounts flush within the jamb profile. Installation requires careful frame-fit verification. Consult the mounting template and datasheet for exact dimensions and fastener locations before beginning installation.
Q: What VMS platforms support the XNB-6001 and SLA-T4680DW together?
A: The XNB-6001 system is ONVIF-compliant, enabling integration with standard VMS platforms (Milestone XProtect, Axis Camera Station, generic ONVIF servers). Verify your specific VMS version supports the codec and profile from the XNB-6001 before deployment.

The SLA-T4680DW represents a genuine specialist solution: a lens module designed explicitly for environments where traditional visible cameras undermine the space. The 4.6mm pinhole lens combined with white finish and hidden fasteners enables installers to deploy 2MP facial identification capability without altering the visual character of a door frame or entry vestibule. The 0.06Lux@F2.5 specification is particularly valuable in typical office and healthcare corridors where ambient lighting sits between 100–300 lux; the module will deliver clean, usable video without requiring active IR supplementation in normal indoor conditions.
Technical Highlights:
- 4.6mm Pinhole Lens Geometry: Enables seamless jamb integration without visible camera housing. The focal length is fixed—no motorized adjustment—so pre-installation aiming assessment is critical. Once mounted, the ±30-degree mechanical adjustment handles minor post-install alignment corrections, but major repositioning requires removal and remount.
- 8-Meter Cable Run: Reduces infrastructure complexity for typical office door-to-equipment-room distances. Beyond 8 meters, custom conduit routing and inline extension become necessary; account for cable management labor and potential signal integrity considerations in the project scope.
- 2MP (1920 × 1080) Pixel Density: Sufficient for facial recognition at entry-point standoff distances (2–5 meters). At distances beyond 5 meters or for crowd-level overview monitoring, the pixel allocation per face becomes marginal; this module is optimized for controlled-access entry, not perimeter or lobby-wide surveillance.
Deployment Considerations:
- XNB-6001 Dependency: The SLA-T4680DW is a lens module only—it requires the XNB-6001 camera body for video processing, compression, and network delivery. Standalone operation is not possible. Ensure your network architecture, PoE infrastructure, and VMS support the XNB-6001 system before adding this module to your bill of materials.
- Interior-Only Design: This module is not IP-rated for outdoor exposure, rain, or dust. Verify all door-frame mounting locations are fully sheltered. Exposed exterior vestibules and weather-facing frames require different hardware from the Hanwha catalog.
- Frame Fit Criticality: Door jamb dimensions vary significantly across installations. The mounting template and datasheet dimensions are non-negotiable; pre-site survey and frame-depth verification prevent costly rework after module arrival.
Deploy the SLA-T4680DW in corporate office buildings, professional healthcare facilities, luxury retail entrances, and secure access gates where facial identification is required but visible security infrastructure would be inappropriate. Pair it with access control readers and magnetic locks to create a unified covert-yet-comprehensive entry security layer. This is a purpose-built tool for a specific scenario—not a general-purpose camera module.
