Hanwha SLA-2M2802D Lens Module for PNM-7002VD
The SLA-2M2802D is a precision optical module engineered specifically for the Hanwha PNM-7002VD dual-sensor surveillance platform. This component pairs a 1/2.8" 2MP CMOS sensor with a fixed 2.8mm F2.0 lens, delivering sharp, wide-area imaging without focus drift or maintenance overhead. Built for professional security integrations, it addresses a specific deployment need: comprehensive single-camera coverage of large open spaces where multiple narrower-angle modules would inflate cost and complexity.
Key Features
- 2MP 1/2.8" CMOS sensor: 2-megapixel resolution provides sufficient detail for identification in retail, office, and manufacturing environments without consuming excessive storage or bandwidth compared to higher-res alternatives.
- 2.8mm fixed focal length, F2.0 maximum aperture: The fixed lens eliminates autofocus complexity and focus-drift failures over time. F2.0 aperture is the optical bottleneck for low-light color performance—larger apertures (like F1.2) exist but add cost and weight; F2.0 represents the practical sweet spot for this sensor class.
- 107.4° horizontal field of view (62.2° vertical, 122.0° diagonal): This wide-angle classification means a single module covers corridor, lobby, or warehouse aisle depth from wall to wall, reducing the need for multiple overlapping cameras and simplifying coverage planning.
- 0.055 Lux minimum illumination (F2.0, 1/30 sec, color): Achieves color video in retail and office spaces with ambient light; rooms lit only by emergency exit signage will not benefit. If you need effective imaging in near-total darkness, you'll need an IR-equipped variant or supplemental IR lighting.
- Pan/tilt/rotate range: -176° to +176° pan, 0° to 51° tilt, -90° to +90° rotate: Enables non-standard mounting—for instance, a perpendicular wall mount or upside-down ceiling install without mechanical adapters. Confirm the PNM-7002VD housing supports the specific angle your installation requires before purchasing.
- Compact form factor: Ø35.5 x 35.9mm, 30g: The lightweight design places minimal stress on mounting brackets and allows flexible placement on camera housings without reinforcement. No separate power or cooling required—optics alone.
- Fixed focus design: Once installed, focus does not drift due to temperature or vibration. Predictable performance reduces troubleshooting calls in high-volume deployments.
Integration and Deployment Context
The SLA-2M2802D is a modular component—it is not a standalone camera. It attaches exclusively to the Hanwha PNM-7002VD dual-sensor platform. Before ordering, confirm your deployment will use the PNM-7002VD as the host camera body. If you are selecting between Hanwha modular lens options, the SLA-2M2802D's 2.8mm fixed lens is optimized for maximum field-of-view coverage; alternatives in the PNM-7002VD line offer narrower focal lengths and magnification for long-range or focused monitoring of specific zones.
Installation integrators should reference the camera selection and deployment guide to validate that wide-angle, fixed-focus optics align with the target environment. For example, a warehouse with ceiling heights above 20 feet may benefit from a longer focal length to resolve detail at distance; a retail lobby where coverage breadth is the priority will favor this module's wide FOV.
The module's pan/tilt/rotate flexibility supports creative mounting in spaces with unusual geometry, but mechanical compatibility with the PNM-7002VD housing at extreme angles should be confirmed on-site or via manufacturer documentation before final deployment.
Frequently Asked Questions
Q: Is the SLA-2M2802D compatible with any camera other than the PNM-7002VD?
A: No. This is a proprietary lens module designed exclusively for the Hanwha PNM-7002VD platform. It cannot be used with other camera models.
Q: Can I use the SLA-2M2802D in complete darkness without supplemental lighting?
A: No. The 0.055 Lux minimum illumination is for color video in low-ambient-light environments (e.g., retail spaces with some lighting). Environments without any ambient light require either an IR-equipped variant or external IR illumination.
Q: What is the difference between the SLA-2M2802D and other lens options for the PNM-7002VD?
A: The SLA-2M2802D prioritizes maximum horizontal field of view (107.4°) with a fixed 2.8mm lens. Other focal lengths in the PNM-7002VD line offer narrower coverage for long-range or focused applications. Choose based on your coverage breadth vs. detail-at-distance requirements.
Q: Does the module's 30-gram weight affect mounting stability?
A: No. The lightweight design is an advantage—it places minimal stress on standard wall and ceiling brackets. The host camera (PNM-7002VD) must still be mounted securely, but the lens module itself adds negligible load.
Q: Can I field-swap the SLA-2M2802D lens if the PNM-7002VD is already installed?
A: Yes, the modular design allows lens replacement in the field. Confirm your integrator has the correct replacement module and follows Hanwha's swap procedure to avoid damaging the camera body or sensor.
Q: What mounting orientations does the pan/tilt/rotate range support?
A: The -176° to +176° pan range and -90° to +90° rotate capability allow wall, ceiling, and perpendicular installations. Tilt range is 0° to 51°. Confirm the PNM-7002VD housing and your bracket can physically accommodate the angle you require before purchase.

The SLA-2M2802D represents a practical modular optics approach for integrators who need to match different lens profiles to the same camera body without stocking multiple hardware SKUs. The 107.4° horizontal field of view and 2.8mm fixed focal length are purpose-built for broad coverage scenarios—retail floors, office lobbies, warehouse entry points—where a single module eliminates the need for overlapping narrow-angle cameras. The module itself (often searched as SLA 2M2802D) is lightweight and passive, but its optical performance is tightly bound to the PNM-7002VD host platform.
Technical Highlights:
- 2.8mm F2.0 optics + 0.055 Lux minimum illumination: This combination is competitive for 2MP fixed lenses in retail and office environments with baseline ambient lighting. F2.0 is the practical limit for this sensor class—going wider (F1.2–F1.6) adds cost and optical complexity without proportional gain in this illumination range. Color video at 0.055 Lux means the module will not perform in dark corridors or dimly lit warehouses; fall back to IR illumination or narrow your deployment scope if you need zero-lux operation.
- 107.4° horizontal FOV delivers 90%+ coverage of a typical 25–30 ft wide space from a single wall or ceiling mount: This FOV reduces system cost by eliminating redundant cameras in large open areas. Compare this to a 50° lens on the same sensor—you'd need two or three modules to achieve equivalent coverage width.
- Fixed focus, no autofocus drift: Once calibrated, the lens will not hunt or drift over months of operation due to temperature swing or vibration. In high-volume warehouse or retail deployments, this eliminates focus-failure callbacks and reduces maintenance scheduling.
- Pan/tilt/rotate range (-176° to +176° pan, -90° to +90° rotate) enables non-standard mounting: Upside-down ceiling placement or perpendicular wall mounting is possible without mechanical adapters. However, the PNM-7002VD housing must physically accommodate the target angle—confirm clearance and cable routing on-site before final installation.
Deployment Considerations:
- This is a lens module only—you must pair it with an operational PNM-7002VD camera body. Ordering the lens alone will not result in a working surveillance unit.
- The 0.055 Lux minimum illumination is a hard floor for color video; facilities relying on 24/7 all-condition monitoring in near-darkness will need supplemental IR lighting or an IR-optimized module variant. Do not assume this module will perform in basement or low-ambient warehouse applications without testing first.
- The wide 107.4° horizontal FOV introduces edge distortion typical of wide-angle optics. Objects near the frame edges will appear stretched or curved. This is normal and not a defect, but it may complicate analytics or detailed forensic review at the frame periphery.
Deploy the SLA-2M2802D in retail lobbies, office atriums, warehouse entry vestibules, or manufacturing floor overview shots where breadth-of-coverage is prioritized over long-range detail. Avoid complete-darkness environments unless paired with external IR illumination.
