Hanwha SLA-5M4600Q 5MP Lens Module
Overview
The Hanwha SLA-5M4600Q is a professional 5MP interchangeable lens module engineered exclusively for the PNM-9000VQ modular camera platform. This lens module delivers fixed focal length flexibility across three configurations—3.7mm, 4.6mm, and 7.0mm—allowing you to optimize field of view for specific surveillance zones without changing camera bodies. Built around a 1/1.8" CMOS sensor paired with day/night capability, the SLA-5M4600Q supports 24/7 surveillance in retail, corporate, industrial, and access-control environments where optical stability and maintenance simplicity are non-negotiable.
Key Features
- 5MP CMOS Sensor (1/1.8"): Delivers sufficient resolution for facial recognition and license plate capture at moderate distances—typically 15–25 feet depending on focal length—reducing false positives in access control and incident investigation workflows.
- Three Fixed Focal Length Options: Choose 3.7mm (wide), 4.6mm (standard), or 7.0mm (telephoto) depending on coverage zone. Fixed optics eliminate focus drift and motorized component failures, lowering maintenance overhead compared to varifocal designs.
- 77.9° Horizontal Field of View (4.6mm): The standard 4.6mm configuration provides balanced coverage for hallways, retail floors, and mid-range entrance areas—wide enough to capture context but narrow enough to preserve detail on faces and objects.
- Day/Night Switching: Transitions automatically from color to monochrome in low-light conditions, maintaining usable video 24/7 without requiring dual-sensor systems or external infrared illumination. This simplifies installation and reduces overall system cost.
- Dedicated PNM-9000VQ Integration: Direct mechanical and electrical compatibility with the PNM-9000VQ platform ensures repeatable optical performance and eliminates compatibility validation overhead during specification and procurement.
- Modular Lens Architecture: Swap focal lengths on-site by changing the lens module rather than replacing entire camera units, streamlining multi-camera deployments and spare parts inventory management.
When to Choose the SLA-5M4600Q
Select this lens module if your surveillance plan standardizes on Hanwha IP cameras and you need fixed focal length reliability across multiple coverage zones. The modular design works well for retail and office environments where you deploy 5–20 cameras spanning entrance points, retail floors, corridors, and perimeter zones—each zone can use the optimal focal length without inventory complexity.
The 5MP resolution paired with 1/1.8" sensor geometry provides edge sharpness and low-light performance suitable for integrations requiring facial recognition or license plate legibility up to 25 feet. If you need longer-range telephoto coverage (50+ feet) or require zoom capability, consider a higher focal length variant in the same lens module family or evaluate a dedicated telephoto camera model.
When to Choose a Different Lens Module
If your deployment requires motorized zoom, consider varifocal or zoom lens modules designed for the PNM-9000VQ platform. If you need higher megapixel density for ultra-close facial recognition or very large-scale perimeter scanning, evaluate 8MP or 12MP sensor variants within the Hanwha catalog. For outdoor installations requiring extreme weather protection, verify IP and IK ratings of the parent PNM-9000VQ housing before finalizing lens selection.
Integration & Compatibility
The SLA-5M4600Q mounts directly to the PNM-9000VQ camera body without adapters. Optical performance, sensor alignment, and mechanical registration are pre-engineered, eliminating focus calibration and reducing commissioning time. Day/night control integrates with standard ONVIF-compliant video management software, allowing remote configuration of color-to-mono thresholds alongside other camera parameters. Consult your network video recorder vendor documentation for resolution and frame rate support across your surveillance network.
Deployment Tips
- Conduct a site survey mapping camera locations, distance-to-subject, and required field of view. Plot each location on a floor plan and annotate the required focal length (3.7mm for large entrance lobbies, 4.6mm for standard corridors and retail, 7.0mm for specific high-value areas or perimeter points spanning 40+ feet).
- Order the SLA-5M4600Q variants in quantities matching your survey, plus one spare of each focal length per 10 cameras deployed. Fixed optics mean minimal spares overhead compared to varifocal systems.
- During commissioning, validate white balance and motion detection sensitivity after day/night switching occurs—low-light transitions sometimes require tuning for your specific lighting environment.
- Inventory the three focal lengths separately to avoid mixing during reinstalls or maintenance cycles.
Frequently Asked Questions
Q: Is the SLA-5M4600Q compatible with other Hanwha camera models?
A: No. The SLA-5M4600Q is designed exclusively for the PNM-9000VQ platform. Do not attempt to install it on other camera bodies.
Q: Can I switch focal lengths in the field?
A: Yes. The lens module disconnects and reconnects on-site. Ensure the camera is powered off during the swap, and verify optical focus after reassembly.
Q: What is the minimum light level at which day/night switching occurs?
A: Typical day/night switching happens around 5–10 lux depending on scene and shutter speed. Consult the PNM-9000VQ camera datasheet for detailed illumination thresholds and sensitivity adjustments via your VMS.
Q: Does the SLA-5M4600Q include infrared illumination?
A: No. The SLA-5M4600Q does not include built-in IR. The PNM-9000VQ camera body may support external IR illumination depending on your specific model variant—verify with your camera datasheet.
Q: What surveillance software supports the PNM-9000VQ with the SLA-5M4600Q?
A: Any ONVIF Profile S-compliant VMS (Milestone XProtect, Axis Camera Station, etc.) will integrate with the PNM-9000VQ. Verify video codec and resolution support in your VMS documentation before deployment.

The SLA-5M4600Q represents a mature approach to modular surveillance design. By decoupling optics from the sensor and processing pipeline, Hanwha allows you to standardize on the PNM-9000VQ platform while tuning focal length to specific coverage zones. Unlike fixed single-lens systems, this modularity cuts deployment complexity when you're managing 10+ cameras across mixed environments—entrance lobby (3.7mm wide), retail floor (4.6mm standard), and back-of-house or perimeter (7.0mm telephoto).
Technical Highlights:
- 1/1.8" CMOS Sensor: This sensor format strikes a practical balance between light gathering (lower noise in dim conditions) and pixel density (5MP on 1/1.8" yields ~1.4µm pixels). Result: you get facial recognition capability at 15–25 feet without excessive noise, suitable for retail loss prevention and access control integration.
- Fixed Focal Length Elimination of Drift: Motors and servos fail; fixed optics do not. In permanent installations, especially outdoor or unattended warehouse deployments, the SLA-5M4600Q avoids focus creep and motorized iris failures that plague varifocal lenses. Maintenance overhead drops measurably over 5+ years.
- Day/Night Automatic Switching: No external IR required, no dual-sensor cost. The SLA-5M4600Q transitions color-to-monochrome automatically, maintaining usable video across a 24-hour cycle. This matters in budget-constrained multi-camera projects where IR illumination would exceed capex or power budgets.
Deployment Considerations:
- Focal Length Commitment: Choose your three focal lengths at procurement time. You cannot zoom; you swap modules in the field. This requires accurate pre-deployment surveying. Under-specify the telephoto length (7.0mm) and you'll be mounting the camera closer to your high-value zone, wasting coverage elsewhere.
- PNM-9000VQ Dependency: This lens module works only on the PNM-9000VQ. Do not confuse it with standalone lens products. If you later adopt a different Hanwha camera platform, the SLA-5M4600Q becomes inventory orphan.
- IR Gaps: If your site requires 24/7 long-distance perimeter monitoring (50+ feet in darkness), day/night switching alone will not deliver readable detail without external illumination. Verify IR coverage specs on your PNM-9000VQ housing or plan external IR lights alongside deployment.
The SLA-5M4600Q excels in mixed-environment corporate and retail deployments where you need fast commissioning, low maintenance, and standard-issue optics across 10–30 cameras. It is not ideal for evolving deployments (where zoom would defer focal-length decisions) or extreme-distance perimeter monitoring (where fixed telephoto lenses hit practical limits).
