Hanwha Techwin SLA-T4680V — 4.60 mm F/2.5 Fixed Pinhole Lens

The Hanwha Techwin SLA-T4680V is a compact, high-performance 4.6mm fixed pinhole lens module designed to deliver exceptional surveillance optics in tight installations. Built to work seamlessly with the XNB-6001 right-angle camera body, this lens module combines a sharp 2MP image at 60fps with superb low-light sensitivity (0.06 lux) and a broad dynamic range (120 dB WDR) to produce clear, reliable footage across challenging scenes. With a 73° horizontal field of view, this lens provides broad scene coverage while maintaining pinpoint detail at mid and long distances. Its discreet form factor and robust construction make it ideal for discreet surveillance in retail, corporate environments, and sensitive access points where visibility is essential without drawing attention. The SLA-T4680V is engineered for installers who demand consistent performance, easy integration, and a flexible mounting solution in a compact footprint.

• 4.6mm focal length with fixed F/2.5 aperture creates a compact pinhole lens module that delivers crisp, high-contrast 2MP imagery at up to 60 frames per second. The small form factor minimizes visibility while preserving edge-to-edge sharpness across the field of view, making it ideal for discreet hallway monitoring, doorway surveillance, and retail corridors where detail matters at mid to long distances.
• Low-light performance and wide dynamic range are at the core of this lens. With 0.06 lux sensitivity and 120 dB WDR, the SLA-T4680V maintains detail in dim environments and handles backlit scenes without washing out highlights or losing shadows. Fine textures, faces, and license-plate-like details remain discernible when lighting is less than ideal, delivering reliable footage around the clock.
• Right-angle body style provides installation flexibility in tight spaces. The compact design fits into recessed housings, ceiling corners, or constrained enclosures, allowing secure mounting without protruding into the scene. This orientation also helps you optimize camera placement for maximum coverage while preserving a clean, low-profile installation that suits retail counters, hallways, and interior security zones.
• Designed for seamless integration with Hanwha Techwin systems. The SLA-T4680V is compatible with the XNB-6001 camera line, enabling straightforward deployment within existing Hanwha ecosystems. Installers gain reliable compatibility, consistent color reproduction, and stable video streams across supported resolutions, reducing setup time and improving overall system reliability.
• Extended cable length for installation versatility. An 8-meter (26-foot) cable provides ample routing options to connect the lens module to the host camera without forcing awkward cable runs or mid-span adapters. This flexibility is particularly valuable in retrofits or multi-camera configurations where distance between the lens and the camera body matters for clean, professional installations.

How to install Hanwha Techwin SLA-T4680V

Installing the SLA-T4680V is straightforward thanks to its fixed lens design and compatibility with Hanwha systems. Start by confirming your camera model compatibility (XNB-6001) and selecting a suitable mounting location that accommodates the right-angle configuration. Secure the lens module into the designated lens port or adapter in the housing, ensuring alignment so that the 73° horizontal field of view targets the intended area—whether it’s a doorway, aisle, or entry point. Route the 8-meter cable with care to avoid tension, interference, or sharp bends, using cable management solutions to keep the installation tidy and protected from wear. Connect the cable to the camera interface, power the system, and verify that the camera output reaches 2MP at 60fps with stable color and minimal motion artifacts. In environments with challenging lighting, rely on the 0.06 lux sensitivity and 120 dB WDR to maintain image detail; adjust exposure settings on the host camera if needed to maximize shadow detail and highlight preservation without compromising overall image quality. For outdoor or semi-exposed applications, consider a suitable protective enclosure and proper sealing to safeguard the fixed lens module from dust and moisture while maintaining optical clarity. Finally, perform a field test across the monitored area to confirm consistent coverage, adjust camera settings for optimal performance, and document the installation for future servicing.
