Hanwha SLA-5M3700P 5MP Lens Module
Overview
The Hanwha SLA-5M3700P is a modular 5MP lens assembly engineered specifically for the PNM-9320VQP camera platform. This interchangeable optic delivers wide-area coverage without the integration complexity of fixed-body designs, giving you the flexibility to standardize on a single camera body while adapting lens configurations to specific coverage requirements across your facility.
Key Features
- 5MP Resolution (2592 × 1944): Paired with a 1/1.8" CMOS sensor, the 5MP output captures sufficient detail for facial recognition and license plate capture at typical indoor ranges, without overshooting your storage and bandwidth budget. At this resolution, you're not paying for megapixels you won't use on short-range deployments like lobbies or hallways.
- 3.7mm Fixed Focal Length: The 3.7mm lens delivers a 97.5° horizontal and 71.9° vertical field of view—the practical wide-angle sweet spot for indoor surveillance. Wide enough to eliminate mounting constraints in confined spaces, but not so wide that optical distortion becomes a problem or distant subjects lose critical detail.
- Day/Night Capable Sensor: The 1/1.8" sensor supports continuous operation from bright daylight through low-light conditions without requiring lens adjustments, filter wheels, or manual spectrum switching. This matters on facilities where lighting transitions happen throughout a shift and you need zero-downtime surveillance.
- Modular Form Factor: Unlike integrated camera bodies, the SLA-5M3700P lens attaches to the PNM-9320VQP platform, allowing you to deploy multiple lens configurations on a single standardized camera body. This reduces spare-parts inventory, simplifies logistics, and lowers total cost of ownership across large multi-site deployments.
- Compatible with Hanwha IP Camera Surveillance Systems: Purpose-built for the PNM-9320VQP, the SLA-5M3700P integrates without compatibility questions or custom adapters. This streamlines procurement, installation, and future support.
- Compact, Installation-Friendly Design: The modular lens assembly fits standard mounting infrastructure, reducing the physical footprint burden on ceiling tiles, wall brackets, or pendant installations in sensitive facility environments.
Integration & Compatibility
This lens module is engineered for direct integration with the Hanwha IP camera platform—specifically the PNM-9320VQP. The optical interface, electrical contacts, and mechanical mount are calibrated to that body, eliminating the need for field adapters or optical alignment. If you're deploying across a mixed facility where different zones demand different FOVs (e.g., entry points needing wider coverage, hallways needing more magnification), you can swap the SLA-5M3700P with alternate Hanwha lens modules on the same camera bodies, avoiding full camera replacements.
When selecting IP surveillance lenses for integration projects, confirm that your chosen platform supports modular optics. Not all manufacturers offer this flexibility—many force you to buy different camera bodies for different focal lengths. Modular lens design reduces redundancy and accelerates deployment timelines.
Ideal Deployment Scenarios
- Corporate Offices & Workplaces: Lobby, reception areas, and common spaces where a single wide-angle lens covers sufficient area without over-specifying resolution.
- Retail Environments: Front-of-store and aisle surveillance requiring broad area coverage with day/night operation to handle lighting changes across opening hours.
- Educational & Institutional Facilities: Hallways, cafeterias, and classroom entrances where the 97.5° FOV eliminates mounting blind spots and reduces camera count.
- Access Points & Entrances: Building entries, loading docks, and security checkpoints where modular lens interchangeability accelerates deployment and supports future expansion.
- Warehouses & Distribution Centers (Interior Zones): Indoor facility monitoring in areas where modular lens solutions provide cost and logistics advantages over fixed-body alternatives.
Frequently Asked Questions
Q: Is the SLA-5M3700P compatible with Hanwha camera models other than the PNM-9320VQP?
A: No. The SLA-5M3700P is engineered specifically for the PNM-9320VQP camera platform. The optical, electrical, and mechanical interfaces are calibrated to that body. Attempting to use it with incompatible camera models may result in optical misalignment or electrical integration failure.
Q: What is the minimum illumination level at which the SLA-5M3700P maintains usable imagery?
A: The 1/1.8" CMOS sensor and day/night capability support continuous operation across varying lighting, from bright daylight to low-light indoor environments. For specific minimum lux thresholds, refer to the PNM-9320VQP camera platform specifications, as lens and sensor performance combine to determine low-light performance.
Q: Can I replace a different Hanwha lens module with the SLA-5M3700P on an existing PNM-9320VQP camera?
A: Yes. The SLA-5M3700P is designed as an interchangeable module. If your PNM-9320VQP is already deployed with a different Hanwha lens module, you can swap the SLA-5M3700P in place, subject to mechanical, electrical, and optical interface compatibility. Consult the PNM-9320VQP documentation for supported lens module variants.
Q: Does the 97.5° horizontal FOV introduce barrel distortion?
A: The 3.7mm focal length with the 1/1.8" sensor delivers wide-area coverage while maintaining edge-to-edge optical clarity. Wide-angle lenses inherently introduce some degree of distortion; the SLA-5M3700P is engineered to minimize visible distortion across the full 5MP sensor at the expense of a slightly narrower FOV than ultra-wide alternatives (which can exceed 120°). The 97.5° horizontal angle represents a practical balance between coverage area and image quality for indoor surveillance.
Q: Is this lens module suitable for outdoor surveillance?
A: The SLA-5M3700P is designed for indoor surveillance. Outdoor deployment requires an environmental rating (IP67 or higher) and weatherproof housing. Consult the compatibility documentation for the PNM-9320VQP to confirm whether outdoor-rated lens modules are available in the same focal length family if outdoor coverage is required.

The SLA-5M3700P addresses a critical requirement in professional surveillance: modular optics for standardized camera platforms. The 3.7mm focal length represents the wide-angle sweet spot—delivering comprehensive area coverage without the barrel distortion or complexity of ultra-wide lenses. The 1/1.8" sensor size balances 5MP resolution with practical low-light performance, while the day/night capability eliminates single-spectrum limitations across indoor facilities.
Technical Highlights:
- 97.5° Horizontal FOV at 3.7mm: Covers broad indoor areas without mounting constraints in confined spaces. The fixed focal length eliminates focus hunting and mechanical complexity, delivering consistent edge-to-edge clarity across the full 5MP frame.
- 1/1.8" CMOS Sensor: Balances 5MP output with realistic low-light sensitivity. Larger than 1/3" sensors found in budget cameras, smaller than 1" formats. This size/megapixel ratio delivers practical detail for identification tasks without inflating storage and bandwidth requirements.
- Day/Night Operation: No spectrum-switching, no adjustable IR filter, no manual recalibration. The sensor handles continuous transitions across changing facility lighting—a real deployment advantage on 24/7 sites.
Deployment Considerations:
- This is modular optics for a specific body. The SLA-5M3700P mounts only to PNM-9320VQP cameras. Confirm your base camera platform before specifying lens modules.
- Wide-angle lenses trade magnification for coverage. At 3.7mm, distant subjects (beyond 15–20 feet) will show less detail than a 6mm or 8mm alternative. Position accordingly or consider a longer focal length if subject identification at distance is critical.
- Modular interchangeability is the cost advantage here. If your facility has mixed coverage requirements (entry points needing 3.7mm wide coverage, hallways needing tighter 6mm), you standardize on the PNM-9320VQP body and swap lenses—no redundant camera bodies, lower logistics overhead.
The SLA-5M3700P is the right choice for integrators deploying standardized multi-camera systems where facility layouts demand consistent wide-angle coverage. Corporate offices, retail environments, and institutional settings with hallway/common-area emphasis benefit most from the modular flexibility and the practical wide FOV. If you're building a custom single-camera system or need magnification at distance, evaluate longer focal length modules in the same Hanwha family.
