Hanwha SLA-T2480V 2MP Fixed Lens Module

Overview

The Hanwha SLA-T2480V is a compact modular lens assembly delivering 2MP resolution with a 2.4mm fixed focal length. This is a lens component engineered to integrate with compatible Hanwha IP camera platforms, not a standalone camera. It combines wide-angle coverage—138° horizontal field of view—with solid low-light performance and wide dynamic range handling. If you're building a modular surveillance system and need broad area coverage without motorized zoom complexity, this module is worth evaluating against alternatives in the same product family.

Key Features

• 2MP Resolution (1920 × 1080): Delivers sufficient detail for facial identification at 3–5 meters and vehicle plate recognition at 8–12 meters in daylight. Useful for retail floors, warehouse entry points, and office common areas where wide coverage matters more than extreme detail.
• 2.4mm Fixed Focal Length: Produces a 138° horizontal field of view—one of the widest angles available in fixed-lens form. Covers a large room or outdoor courtyard with a single unit, reducing camera count and infrastructure cost.
• 60fps Video Capture: Eliminates motion blur during fast activity; critical for activity review, incident investigation, and detecting rapid movements. At 60fps, you'll see smooth playback even when objects move quickly across frame.
• 120dB Wide Dynamic Range (WDR): In mixed-lighting scenes—such as a warehouse with bright skylights and dark aisles, or a retail space with windows and interior shadows—WDR preserves usable detail in both bright and dark regions simultaneously. Without it, you'd have to choose: expose for the bright areas and lose detail in shadows, or expose for shadows and wash out the bright window.
• 0.45 Lux Minimum Illumination: Operates in very dim conditions without requiring IR illumination. A typical office at night (after lights off) is roughly 0.1–0.5 lux; this module will capture recognizable detail at the higher end of that range. In true darkness, you'd still need IR or external lighting.
• 8-Meter Integrated Cable: Reduces the need for additional cabling to the control unit or NVR. Useful when mounting the lens module 20–25 feet away from your recorder—saves labor and materials compared to running a separate cable run.

Integration & Compatibility

The SLA-T2480V is designed for direct integration with Hanwha's modular camera ecosystems, particularly the XNB-6001 surveillance platform. Before purchase, verify your specific camera model supports this lens module. Modular lens systems are not universally cross-compatible; installing the wrong lens on a camera body can cause focus issues or poor optical alignment. Confirm compatibility with your system integrator or review the host camera's technical documentation.

Typical Deployment Scenarios

Suitable for wide-angle fixed-position surveillance in retail environments, warehouse receiving areas, office building lobbies, and parking structures. The 138° field of view makes it effective for monitoring large open spaces where you want minimal blind spots. The 60fps refresh and low-light sensitivity support activity-heavy environments such as loading docks and commercial kitchens. Not intended for long-distance recognition tasks (e.g., parking lot perimeter) where higher magnification is necessary.

When to Choose a Different Model

If your application demands:

• Higher magnification: Consider a motorized varifocal lens module in the same Hanwha family if your camera body supports it. A 4–8mm or 3–10mm module will let you zoom in on distant subjects.
• Higher resolution: Evaluate a 4MP or 5MP fixed-lens module if you need sharper facial or license plate detail. Resolution and field of view are tradeoffs—wider always means lower effective resolution at distance.
• Outdoor/harsh weather: Verify the SLA-T2480V's environmental rating (IP and IK codes) against your installation location. If the datasheet doesn't specify an IP67 or IP68 rating, this module may be indoor-only; outdoor installations would require a weatherproof housing or a dedicated outdoor lens module.

Frequently Asked Questions

Q: Does the SLA-T2480V work as a standalone camera?

A: No. This is a lens module component. It requires a compatible Hanwha camera body (such as the XNB-6001) to function. It is not a complete camera unit.

Q: What is the 138° field of view in practical terms?

A: A 138° horizontal field of view means the lens captures a very wide scene—roughly equivalent to standing in a room and seeing almost from one side wall to the other without turning your head. In a 20-foot-wide retail space, you can monitor the entire floor with one camera position.

Q: Can I use the SLA-T2480V outdoors?

A: Depends on the environmental rating stated in the full datasheet. The available evidence does not specify an IP or IK rating. Before outdoor deployment, confirm the module's IP rating matches your climate (IP67 minimum for rain exposure, IP68 for submersion risk). If the module lacks an outdoor rating, mounting it in a weatherproof housing may be necessary.

Q: How does the 0.45 Lux sensitivity compare to other modules?

A: 0.45 Lux is a strong low-light spec for a 2MP fixed module. It allows operation in near-darkness without IR illumination—useful if you want to avoid IR spillover artifacts or power consumption. However, in complete darkness (0 lux), any camera requires IR or external light.

Q: Is the 8-meter cable length fixed, or can it be extended?

A: The module includes an integrated 8-meter cable. If you need a longer run, consult the camera body's wiring specifications—you may need additional cabling or a repeater, depending on the signal type (video, power, or both).

Q: How does WDR affect storage requirements?

A: WDR is a real-time imaging function that does not directly change file size. However, because WDR delivers more usable detail in both bright and dark areas, you may be able to use lower compression settings (like H.264 instead of H.265), which increases bitrate slightly. If you're recording 24/7 across many cameras, measure the actual bitrate before and after WDR is enabled.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The SLA-T2480V represents a deliberate choice for integrators building modular camera platforms that prioritize area coverage over magnification. The 138° field of view from a 2.4mm fixed lens is legitimately broad—you're covering roughly 50–60 linear feet of a retail floor or warehouse aisle in a single frame. Paired with 60fps refresh, this module delivers fluid motion capture suitable for activity review and incident reconstruction, not just static monitoring.

Technical Highlights:

• 120dB WDR: Mixed-lighting scenes (skylights + aisles, or storefronts with windows) are common in commercial deployments. 120dB WDR ensures you capture usable detail in both the bright exterior and shadowed interior simultaneously—a real-world advantage over cameras without WDR, where you'd lose either highlights or shadow detail.
• 0.45 Lux Performance: This low-light rating outperforms many competitive 2MP modules in the same form factor. You're not dependent on IR illumination for near-darkness operation, which reduces IR artifacts and power draw—meaningful if you're deploying dozens of units on a limited power budget.
• 60fps at 2MP: Motion clarity at this resolution and frame rate is solid for identifying people and objects in transit. Warehouse receiving, retail floor activity, and office entrance monitoring all benefit from this fluidity.
• 8-Meter Cable: Eliminates the need for a separate video/power run in mid-range installations. Reduces labor, cabling cost, and junction points—fewer connections mean fewer failure modes in long-term deployments.

Deployment Considerations:

• Modular Compatibility: This is a component lens, not a standalone camera. You must verify host camera compatibility before ordering. Installing a lens module on an incompatible body wastes time and creates support friction.
• No Zoom: The 2.4mm fixed focal length is wide but not adjustable. If a specific application needs magnification (e.g., distant vehicle plate recognition), this module is not the answer—you'd need a varifocal or motorized option within the same Hanwha family.
• Environmental Rating Unknown: The available evidence does not specify IP or IK ratings. Before outdoor deployment, pull the full datasheet and confirm weather resistance. Indoor-only modules in wet or dusty environments will fail prematurely.

Best fit: Retail and warehouse integrations where you're managing floor-level activity across 40–80-foot spaces and can tolerate fixed wide-angle coverage. Avoid scenarios where you need both wide coverage and the ability to zoom in on distant subjects in the same camera—that's a job for a varifocal module. The SLA-T2480V is built for integrators who know upfront that they need area surveillance, not hunt-and-zoom capabilities.
