Hanwha SLA-T2480VA 2.4mm Fixed Lens Module

The Hanwha SLA-T2480VA is a specialized interchangeable lens module designed to expand field-of-view coverage on compatible Hanwha IP cameras. This accessory delivers a 138° horizontal field of view—significantly wider than standard fixed lenses—allowing integrators to cover expansive interior spaces without adding multiple camera sensors to the system. The compact module connects via RJ12 interface directly to the host camera unit, enabling straightforward retrofit upgrades with minimal installation complexity.

Key Features

• 2.4mm focal length with 138° horizontal field of view: Covers broad interior spaces—corridors, retail floors, warehouse sections—from a single mounting location. The 165° diagonal FOV captures edge-to-edge awareness, reducing blind spots in wide-open environments.
• 2MP 1/2.8" CMOS sensor: Delivers sufficient pixel density for facial recognition and object identification at typical indoor distances, balancing resolution with manageable bandwidth on standard network infrastructure.
• F2.0 maximum aperture: Opens wider than typical fixed lenses, allowing more light to reach the sensor—critical when ambient illumination varies or drops unpredictably during operational hours.
• 0.045 Lux minimum illumination in color mode: Produces usable color imagery in dimly lit retail backrooms, warehouse aisles, and office corridors without requiring supplemental lighting or switching to infrared mode. This low threshold preserves color detail and detail visibility where thermal or night-vision modes would lose context.
• Fixed focus design: Eliminates mechanical drift over months of operation. No autofocus motors or calibration routines to maintain; once installed, focus remains stable across temperature swings and vibration, reducing unplanned maintenance visits.
• RJ12 connector interface: Plugs directly into the host camera's lens socket, requiring no external power supply, USB bridge, or auxiliary cabling. Installation is a single-step connection; removal is equally simple for field upgrades or swaps.
• Compact dimensions (30 x 27.9 x 45mm, 328g): Adds minimal weight and bulk to the main camera unit, allowing flexible mounting on poles, walls, or ceiling surfaces without requiring reinforced brackets or strain-relief accessories.

Integration & Compatibility

The SLA-T2480VA (often searched as SLA T2480VA) integrates exclusively with compatible Hanwha host cameras equipped with an interchangeable lens slot and RJ12 lens interface. Verify host camera model compatibility before ordering; the module cannot be retrofitted to non-Hanwha systems or older fixed-lens Hanwha models. Once mated, the lens assembly and host camera function as a unified imaging system—no separate configuration or network provisioning is required. The RJ12 connection handles both signal and power delivery, eliminating complexity in field installations.

Deployment Scenarios

Integrators deploy the SLA-T2480VA in retrofit scenarios where existing Hanwha camera installations require expanded coverage. Retail environments benefit from the 138° horizontal field to monitor entire sales floors from a single camera. Warehouse and logistics facilities use the module to survey aisles and packing zones. Office and facility security teams install the lens in hallways and open-plan spaces where wall-mounted positioning allows the wide angle to cover entrance approaches and circulation routes simultaneously. The low-light sensitivity supports indoor deployments without assuming supplemental lighting infrastructure.

For camera placement and field-of-view planning, the 138° horizontal coverage simplifies design calculations—fewer cameras are needed to achieve equivalent area coverage compared to narrow fixed lenses, reducing overall system cost and cabling infrastructure.

Frequently Asked Questions

Q: Which Hanwha camera models are compatible with the SLA-T2480VA?

A: The SLA-T2480VA is designed for Hanwha surveillance cameras equipped with an interchangeable RJ12 lens socket. Consult the host camera's datasheet or contact the manufacturer to confirm compatibility before purchasing. Not all Hanwha models support interchangeable lens modules.

Q: Can I change lenses in the field, or is the SLA-T2480VA permanent?

A: The module can be removed and replaced with alternative Hanwha lens modules of the same RJ12 interface, allowing field upgrades if coverage requirements change. Ensure the camera is powered down before disconnecting or installing a lens module.

Q: What is the minimum illumination threshold, and will it work in near-dark environments?

A: The 0.045 Lux minimum illumination in color mode supports dimly lit indoor spaces. However, this is not night-vision; if the host camera includes infrared illuminators, they activate when visible light drops below usable thresholds. Consult the host camera's specifications for IR range and low-light switching behavior.

Q: Does the 2.4mm lens provide sufficient detail for facial recognition?

A: The 2MP sensor and 2.4mm lens deliver acceptable resolution for facial identification at typical indoor mounting heights (8–12 feet). At greater distances or extreme angles, detail may degrade. Use the 138° field to confirm facial area coverage during design phase.

Q: What mounting options are available for the SLA-T2480VA?

A: Mounting depends on the host camera's form factor and mount type. The lens module itself is compact and lightweight, so standard wall, ceiling, or pendant mounts compatible with the host camera will support the assembly without additional hardware.

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

The SLA-T2480VA serves a specific retrofit niche: integrators tasked with extending coverage on existing Hanwha installations without adding cameras. The 138° horizontal field of view—roughly 55° wider than a typical 2.8mm reference lens—is the defining strength. For a retail floor or warehouse aisle, this translates directly to fewer sensors needed to achieve equivalent perimeter awareness, which cuts cabling, power budgeting, and NVR channel licensing.

Technical Highlights:

• F2.0 aperture + 0.045 Lux floor: Together these deliver color imaging in environments where competitors' F2.4 or narrower optics would force a switch to grayscale or IR. Real-world impact: no supplemental lighting retrofit, no thermal fallback. Matters in retail stockrooms, warehouse aisles, and office corridors where context and color preservation are non-negotiable.
• Fixed focus mechanism: No autofocus creep, no servo maintenance. Over 12–24 months of unattended operation, this eliminates mechanical drift failures that plague motorized focus systems in thermal cycling environments.
• RJ12 interface: Single-point connection, no auxiliary power, no USB bridge, no configuration. Installation time is measured in minutes. Removal is equally frictionless if coverage strategy changes.

Deployment Considerations:

• Compatibility is strict: verify the host camera model explicitly supports RJ12 interchangeable lens modules. Retrofit retrofitting to a non-compatible unit is a non-starter.
• The 2MP sensor resolution is adequate for facial identification at typical indoor mounting heights (8–12 feet), but recognition accuracy degrades rapidly beyond 15 feet or at oblique angles. Size your deployment zone accordingly during design phase.
• If the environment includes extended periods of near-total darkness (e.g., warehouse with minimal ambient light), confirm the host camera includes IR illuminators; the SLA-T2480VA itself is passive and cannot compensate for zero ambient light.

Deploy the SLA-T2480VA in retrofit projects where you're upgrading an existing Hanwha system to cover a wider area without adding equipment to your infrastructure footprint. It's a cost-effective path to expanded FOV for integrators committed to the Hanwha ecosystem.
