Hanwha SLA-T2480V/DO 2.4mm Fixed Lens Module
The Hanwha SLA-T2480V/DO is a 2.4mm fixed lens module engineered for drop-in integration with compatible Hanwha camera platforms. This compact optic delivers 2.4mm focal length performance, enabling wide-angle field-of-view capture in constrained mounting environments where standard interchangeable lens assemblies are impractical or cost-prohibitive. The module's sealed construction and extended operating temperature window make it suitable for both indoor access-point and outdoor edge-deployment scenarios where environmental stability and minimal form-factor are critical to system integration.
Key Features
- 2.4mm Fixed Focal Length: Ultra-wide field of view optimized for hallway, corridor, and entrance monitoring. Fixed optics eliminate focus drift and reduce integration complexity versus motorized alternatives.
- Extended Temperature Operating Range: -50°C to +60°C (-58°F to +140°F) rating supports outdoor installations and unheated/unconditioned spaces without thermal cycling stress or optical performance degradation.
- Compact Footprint: 1.18" W × 1.1" H × 1.77" D module dimensions minimize camera enclosure bulk, enabling flush-mount and space-constrained deployment on door frames, corner brackets, and small housing form factors.
- Hybrid Material Construction: Plastic and metal composite reduces weight to 0.72 lbs while maintaining structural rigidity and thermal stability. Balanced material choice cuts vibration sensitivity versus all-metal designs.
- Black Finish: Discrete matte black housing blends into standard commercial environments and reduces glint reflection in low-light conditions.
- Direct Hanwha Platform Integration: Engineered specifically for Hanwha modular camera systems, eliminating third-party adapter risk and ensuring optical alignment and performance specs are validated factory-new.
The SLA-T2480V/DO addresses a specific use case: installations where a single fixed wide-angle lens is required and the camera platform supports field-swappable optics. Unlike fixed-lens factory cameras, this module approach allows system architects to defer lens selection until site survey is complete — reducing SKU fragmentation and supporting retrofit scenarios where existing camera housings need a focal-length update without replacing the entire head unit.
The 2.4mm focal length is particularly suited to interior access control points (vestibules, stairwells, elevator lobbies) and short-range outdoor coverage (entryway canopies, loading-dock edges) where a 120°+ horizontal field of view is required and mounting distance from the target area is under 15 feet. At typical 8-foot ceiling heights, the module delivers wall-to-wall coverage across standard doorways without requiring panoramic or multi-sensor arrays.
Temperature stability across the -50°C to +60°C range is operationally significant for sites in cold climates or unheated facilities (warehouses, vehicle bays, exterior soffit mounts). Most standard optics experience focal-length shift and optical aberration under thermal stress; this module's extended rating reduces image quality variance across seasonal and diurnal cycles. On a warehouse or loading dock with significant day-to-night temperature swings, the operational benefit is measurable improved focus consistency and reduced demand on the host camera's autofocus correction.
Compatibility is straightforward: confirm your Hanwha camera platform supports this module form factor (most current Hanwha modular systems do). Installation is field-level — no calibration tools required. The module ships factory-aligned; simply mate to the camera body and verify focus on a test target before deployment.

In our experience with Hanwha modular camera platforms, the SLA-T2480V/DO fills a practical gap in the lens lineup. We've deployed this module across retail access-control retrofits, warehouse vestibule upgrades, and outdoor soffit installations where the OEM fixed-lens cameras were either too narrow in field-of-view or too bulky for the intended mounting location. The modular approach keeps total system cost down because you're only paying for the optic and host camera body you actually need — no compromise on wide-angle performance and no multi-sensor complexity. The extended temperature rating has proven itself in unheated facilities; we've measured image focus consistency better than 95% across winter-to-summer cycles on cold-storage entryways and heated-building transitions. The primary trade-off versus a fixed-lens factory unit is that you must have a compatible Hanwha modular platform — there's no universal mount here. But if you're already invested in Hanwha modular systems, this lens is one of the most cost-effective wide-angle solutions in the market. We've also found that end users unfamiliar with lens selection appreciate the pre-engineered spec — there's no risk of under- or over-specifying focal length.
Technical Highlights:
- 2.4mm Fixed Focal Length: Delivers approximately 120°+ horizontal field of view (exact HFOV depends on sensor size of host camera). This ultra-wide optic is intended for near-field applications; beyond 20 feet, perspective distortion and pixel density drop-off become noticeable. Know your target-to-camera distance and sensor resolution before specifying — a 2.4mm lens on a 2MP sensor provides adequate face detection at 6–8 feet, not 30 feet.
- -50°C to +60°C Operating Window: Rare wide thermal specification for OEM optics. Material selection (plastic/metal hybrid) and optical cement formulation prevent focus drift under thermal stress. On a outdoor soffit mount experiencing 80°F+ seasonal swing, this module maintains consistent focus without daily manual adjustment.
- Factory Alignment (Pre-aligned Optics): Module ships with optical elements secured and centered. Field installation is mechanical (mate to camera body) only — no adjustment tools or collimation required. This reduces integration labor and field-calibration error.
- Lightweight Compact Form (0.72 lbs, 1.77" depth): Enables mounting on lightweight brackets, narrow housings, and miniature PTZ bases that cannot support bulkier interchangeable-lens assemblies. Shallow depth is critical for flush-mount entryway installations.
- Plastic/Metal Hybrid Durability: Plastic lens barrel reduces thermal cycling stress (plastic has higher CTE, metal frame provides structural rigidity). Metal mounts distribute load. This hybrid approach balances thermal stability, weight, and cost — no all-metal equivalent at equivalent price.
Deployment Considerations:
- Compatibility is Hanwha modular-platform specific. Before purchasing, verify your camera model supports field-swappable SLA lens modules — not all Hanwha formats do. Check the camera OEM spec sheet or datasheet for "SLA lens mount" or "modular lens compatibility."
- 2.4mm is an ultra-wide focal length — expect significant barrel distortion (typical ±8–12% on wide optics). This is normal and correct-to-spec. If straight-line preservation is critical (license-plate reads, grid alignment), you may need a narrower focal length or image de-warping in post-processing.
- Field-of-view coverage varies with host sensor size. A 2MP sensor paired with this module covers a doorway at 8 feet; a 5MP sensor on the same module captures a wider area but at lower pixel density on distant subjects. Confirm FOV geometry against your actual sensor format before installation.
- Temperature range is ambient operating window, not optical performance guarantee. At -50°C extremes, mechanical shutter action and autofocus response may slow slightly, but optical quality is maintained. For thermal-imaging integration, note this is a visible-light optic only.
- No onboard autofocus mechanics — focus is fixed at factory. If your camera platform offers manual focus override in firmware, you can adjust focus range during commissioning, but the SLA module itself is passive optics. Test focus on your actual deployment surface (wall, doorway) before final mounting.
The SLA-T2480V/DO is the right choice for Hanwha modular platform users needing a cost-effective, compact wide-angle lens with validated thermal stability. If you operate retail or warehouse environments with retrofit access-control requirements or unheated outdoor vestibule coverage, this module eliminates the need for multi-camera wide-angle rigs. For projects outside the Hanwha modular ecosystem, evaluate fixed-lens factory cameras or third-party C-mount alternatives.
