Hanwha SLA-2M2402D 2MP Lens Module for Dual-Sensor Surveillance
The Hanwha SLA-2M2402D is a precision lens module engineered as a dedicated optics component for the PNM-7002VD dual-sensor surveillance camera. This is not a standalone camera—it is a specialized accessory that integrates into the PNM-7002VD platform to deliver a specific wide-angle field of view and low-light imaging profile. The module pairs a 1/2.8" 2MP CMOS sensor with 2.4mm fixed focal length optics and an F2.0 maximum aperture, optimized for comprehensive area coverage in retail, parking, lobby, and perimeter applications where sight lines and context take priority over telephoto reach.
Key Features
- 2.4mm Fixed Focal Length with F2.0 Aperture: The f/2.0 maximum aperture gathers significantly more light than typical f/4.0 or f/5.6 fixed lenses. This enables color imaging at just 0.055 lux with a 1/30 second exposure—meaning you retain color detail in dim retail aisles, parking structures, and stairwells without forcing the system into low-light monochrome mode or adding thermal imaging complexity. Fewer lens modules overall to achieve comprehensive area coverage translates directly to lower infrastructure and cabling costs.
- 135.4° Horizontal / 161.6° Diagonal Field of View: This wide perspective covers nearly an entire retail section or lobby entrance in a single frame, reducing the total number of lens modules required for comprehensive area surveillance. Trade-off: facial detail is smaller than a narrower lens at the same distance, so prioritize this module where area awareness and incident context matter more than close-range facial identification. For high-value item zones requiring facial clarity, pair multiple SLA-2M2402D units or consider a narrower-angle variant in the Hanwha lens family.
- 0.055 Lux Color Sensitivity: Exceptional low-light performance allows reliable color recognition in conditions most fixed lenses handle only in black and white. Parking lot entrance lighting, after-hours retail, and dusk/dawn transitions stay in color—useful for event correlation and suspect description without requiring additional infrared or thermal overhead. This eliminates the cost and complexity of bolted-on IR illumination in many indoor and semi-outdoor deployments.
- Compact Dimensions (Ø35.5 × 35.9mm, 30g): The small footprint and minimal weight fit seamlessly into the dual-sensor PNM-7002VD housing without altering mounting or support requirements. Integrators can swap between lens modules on the same camera body without re-engineering the installation—a genuine advantage during phased rollouts or when coverage priorities shift mid-project.
- Flexible Pan/Tilt/Rotate Adjustment: Pan range of ±176°, tilt from 0° to 30°, and rotation from ±90° accommodates ceiling, wall, and corner installations with easy directional tuning post-deployment. This adjustability is critical for correcting sight lines when structural obstructions or viewing angle requirements change after initial positioning—no return to inventory or replacement order required.
- Fixed Focus Design: No autofocus mechanism to calibrate or fail. Once the module is optically focused at commissioning, it remains stable across temperature swings and vibration—a significant advantage in 24/7 unattended deployments where maintenance visits are infrequent. The trade-off is that you must set the working distance and depth-of-field at installation; refocusing requires physical adjustment or replacement. This is acceptable for fixed-mount lobby and entrance applications but unsuitable for applications requiring dynamic zoom or refocus.
- Modular Integration with PNM-7002VD: The SLA-2M2402D is purpose-built for the Hanwha PNM-7002VD dual-sensor platform, enabling rapid swaps between wide-angle and narrower-angle optics without disturbing the camera body or power/network connections. This modularity is particularly valuable in retail and lobby environments where initial coverage assumptions often shift during commissioning.
Integration & Compatibility
The SLA-2M2402D is a direct optical accessory for the PNM-7002VD. It is not compatible with standalone fixed cameras or PTZ units. Installation requires mounting the module into the PNM-7002VD lens turret and establishing optical focus at commissioning. Confirm your camera model is PNM-7002VD before ordering. For NVR and storage planning, the 2MP resolution generates approximately 1–2 Mbps per stream in H.265 at 30 fps depending on scene complexity and motion levels—well within standard gigabit PoE cabling infrastructure.
Frequently Asked Questions
Q: Is the SLA-2M2402D a complete camera, or does it require a host camera?
A: The SLA-2M2402D is a lens module only. It is designed to integrate into the Hanwha PNM-7002VD dual-sensor camera body. It cannot operate as a standalone camera.
Q: What is the minimum working distance for the SLA-2M2402D?
A: The module features fixed focus, so the working distance and depth-of-field are set at commissioning. Verify your expected mounting height and coverage distance before installation. Once focused, refocusing requires physical adjustment of the lens element.
Q: Will the SLA-2M2402D operate in very low light without infrared illumination?
A: Yes. The 0.055 lux color sensitivity at F2.0 (1/30 second exposure) is exceptional for a fixed 2MP module. Most typical indoor and semi-outdoor ambient lighting will yield acceptable color video without IR. However, total darkness or near-zero ambient light will require the PNM-7002VD's built-in IR capability if available on that camera body.
Q: Can I adjust the lens after installation?
A: The SLA-2M2402D offers ±176° pan, 0–30° tilt, and ±90° rotate adjustment for directional aiming. However, the focal length is fixed at 2.4mm and the focus is set at commissioning. You cannot zoom or refocus without disassembling the module.
Q: What other lens modules are available for the PNM-7002VD?
A: Hanwha offers other fixed and motorized lens variants for the PNM-7002VD platform. Consult the Hanwha camera lens catalog or your integrator for alternative focal lengths and field-of-view options.
Q: Is the SLA-2M2402D rated for outdoor installation?
A: The module has a black plastic construction rated for indoor and semi-outdoor environments. The degree of weather resistance depends on the PNM-7002VD camera body's environmental rating. Verify the full camera assembly meets your site's rain, dust, and temperature requirements before specifying for exposed outdoor mounting.
When to Choose a Different Model
The SLA-2M2402D excels in wide-angle, fixed-mount area surveillance. If your deployment requires closer facial detail at distance, consider a narrower fixed lens or motorized varifocal variant in the Hanwha PNM-7002VD lens lineup. If you need pan-tilt-zoom capability, the SLA-2M2402D is not suitable—evaluate full PTZ cameras instead. If the PNM-7002VD dual-sensor architecture itself doesn't match your application, start with camera selection fundamentals to confirm the base platform meets your requirements.

The SLA-2M2402D is purpose-built for deployments where wide coverage and low-light color retention matter more than zoom or facial resolution. The 0.055 lux sensitivity at F2.0 is genuinely useful—you're looking at color surveillance in most retail and lobby lighting without IR overhead. The 135.4° horizontal field of view is broad enough to cover a parking lot entrance or retail aisle in a single frame, which reduces module count and infrastructure cost compared to multiple narrower lenses.
Technical Highlights:
- F2.0 Aperture + 0.055 Lux: The combination delivers color imaging in lighting conditions where f/4.0 lenses force monochrome or require IR. Real-world payoff: fewer IR projectors to maintain and fewer storage GB per frame due to color stability rather than IR noise artifacts.
- 135.4° Horizontal FOV: Covers ~45–50 linear feet of retail or lobby space from typical 8–10 foot ceiling heights. One module often replaces two narrower lenses, cutting integration labor and switch port count.
- Fixed Focus + ±176° Pan/±90° Rotate: Once commissioned, zero autofocus drift across temperature and 24/7 operation. Directional adjustment handles most ceiling and corner mount variations without disassembly.
Deployment Considerations:
- Fixed focus means you must confirm working distance and depth-of-field at commissioning. If facial detail is discovered to be too small during initial assessment, you cannot refocus remotely—physical return to the site is required.
- The SLA-2M2402D is a module only; you must already own or be specifying a PNM-7002VD camera body. Confirm platform compatibility before ordering; it is not a retrofit for older Hanwha single-sensor bodies.
- Weather resistance depends on the host camera body. For outdoor exposed mounting, verify the PNM-7002VD itself meets your IP and temperature ratings—the lens module alone does not guarantee full environmental resilience.
Spec this module when your client's priority is comprehensive area awareness in controlled or semi-outdoor lighting—retail loss prevention, lobby entry logging, parking structure overviews. Avoid it when facial identification at distance or dynamic zoom is a hard requirement. The low-light color performance is the real differentiator here; that F2.0 aperture and 0.055 lux sensitivity will save you from IR projector clutter and maintenance in 80% of indoor retail and hospitality deployments.
