Hanwha SLA-2M3602D Lens Module for PNM-7002VD

Hanwha SLA-2M3602D Lens Module for Dual-Sensor Platform

The SLA-2M3602D is a precision optical lens module engineered for integration with Hanwha's PNM-7002VD dual-sensor platform. This compact lens combines a 1/2.8" 2MP CMOS imaging sensor with a fixed 3.6mm focal length to deliver consistent surveillance imagery across indoor and outdoor monitoring environments. Built for professional security deployments where reliable optical quality and mechanical flexibility matter.

Key Features

• 1/2.8" 2MP CMOS Sensor: Delivers 2 megapixel resolution suitable for medium-range monitoring where detail and coverage must coexist—enough to resolve faces or license plates at 20–30 feet under good lighting, without the storage overhead of 5MP or higher.
• Fixed 3.6mm Focal Length: Eliminates the mechanical complexity and potential failure points of zoom or varifocal mechanisms. A fixed lens means no autofocus lag, no motor noise, and predictable field of view across the entire sensor lifetime.
• F2.0 Maximum Aperture: Maximizes light transmission through the optical path. This translates directly to usable color video in dim environments—critical for warehouses, parking structures, or outdoor sites without supplemental lighting.
• 94.8° Horizontal FOV, 114.3° Diagonal: Wide enough to capture situational context in a single frame—corridors, loading docks, or retail floors—without requiring pan/tilt to track activity. Diagonal coverage of 114.3° means less video real estate wasted on ceiling or floor.
• 0.055 Lux Minimum Illumination (F2.0, 1/30sec, Color): Operates in near-darkness without switching to grayscale or activating IR. For facilities running 24/7 with minimal ambient light, this eliminates the need for external illumination or thermal cameras in many cases, reducing total system cost.
• Motorized Pan/Tilt/Rotate: Pan range of −176° to +176°, tilt from 0° to 64°, and rotation of −90° to +90° allow broad directional coverage without repositioning the physical module. Useful for adjusting view angle post-installation without rewiring or remounting hardware.
• Compact Form Factor—Ø35.5 × 35.9mm, 30g: Fits into tight mounting spaces and doesn't impose significant mechanical load on support structures. Low mass simplifies cable routing and reduces strain on mounting brackets, particularly in retrofit installations on existing infrastructure.
• Durable Black Plastic Construction: Resistant to scratching and UV degradation in outdoor environments. Plastic housing also means no thermal conduction concerns in extreme temperatures and lower cost than metal alternatives without sacrificing robustness for typical surveillance duty cycles.

Integration & Compatibility

This lens module is purpose-built for the PNM-7002VD dual-sensor platform and should not be substituted with other lens variants without verifying mechanical and electrical compatibility with Hanwha. The motorized pan/tilt/rotate function requires integration with the host platform's motor control interface—consult the platform documentation to confirm driver support and control protocol.

When deploying this lens in a Hanwha surveillance line, verify that your NVR or recording appliance supports ONVIF or manufacturer-native drivers for motion control. Ensure cabling between the lens module and the PNM-7002VD host platform is routed to minimize electromagnetic interference, especially in facilities with industrial machinery or high-frequency equipment nearby.

Optical Performance in Practice

The 3.6mm focal length establishes a practical balance: wide enough to monitor a warehouse floor section or parking lot span in a single frame, yet narrow enough to resolve detail—a face at 25 feet, a vehicle license plate at 30 feet—under typical fluorescent or daylight conditions. The 0.055 lux rating means the module remains in full-color operation in stairwells, loading areas at dusk, or indoor spaces lit only by exit signs, without requiring infrared illumination or grayscale fallback.

Integrators often specify fixed-focal-length lenses like the SLA-2M3602D when deployment sites have stable, predictable monitoring geometry—known distances and viewing angles reduce the need for zoom adjustability and lower long-term maintenance costs.

Recommended Deployment Scenarios

• Multi-sensor surveillance systems where modular lens components enable rapid field replacement or standardization across a fleet.
• Medium-range outdoor and indoor monitoring in retail, hospitality, or light industrial settings.
• Facilities with variable ambient lighting—day/night cycles without supplemental lighting infrastructure.
• Installations requiring post-mount view angle adjustment via motorized pan/tilt/rotate without physical repositioning.
• Security systems where compact form factor and low power consumption reduce mounting complexity and infrastructure load.

Frequently Asked Questions

Q: Is the SLA-2M3602D compatible with cameras other than the PNM-7002VD?

A: This lens module is engineered specifically for the PNM-7002VD dual-sensor platform. Cross-compatibility with other Hanwha models or third-party platforms is not supported without verification from the manufacturer. Always confirm mechanical and electrical connector compatibility before attempting substitution.

Q: What is the minimum illumination requirement, and does it include infrared?

A: The 0.055 lux specification is for color operation at F2.0 and 1/30 second shutter in ambient light—no infrared. If the PNM-7002VD platform includes integrated IR illumination, that would supplement this module's low-light performance, but the lens itself is passive optical.

Q: Can I adjust the field of view after installation?

A: The focal length is fixed at 3.6mm, so you cannot zoom. However, the motorized pan/tilt/rotate capability (−176° to +176° pan, 0° to 64° tilt, −90° to +90° rotation) allows significant repositioning of the viewing angle without physically removing or remounting the lens module.

Q: What power does the motorized pan/tilt/rotate function consume?

A: Power consumption for the motor control is integrated into the host platform's power supply. Consult the PNM-7002VD datasheet or your system integrator for total power draw when motors are active; this will affect PoE budget planning if the platform draws power via Ethernet.

Q: Is the SLA-2M3602D IP-rated for outdoor use?

A: The lens module itself is not separately rated. Outdoor durability depends on the PNM-7002VD platform's IP rating and any external housing or mounting enclosure. Verify the host platform's environmental specifications before deploying in unprotected outdoor locations.

Q: Does the module support motorized focus or iris adjustment?

A: The SLA-2M3602D is a fixed-focal-length, fixed-aperture (F2.0) design. There is no autofocus or motorized iris. Exposure control is managed by the image sensor and the host platform's firmware, not by lens mechanics.

Perspective based on aggregated and affiliated engineering team experience.

The SLA-2M3602D represents a purpose-built solution for integrators standardizing on Hanwha's modular dual-sensor platform. Fixed focal length eliminates the complexity of zoom mechanisms—no autofocus hunting, no mechanical wear, and predictable optical performance across the sensor's operational life. That 0.055 lux minimum illumination (F2.0, 1/30sec, color) is your real lever here: most facilities can eliminate supplemental lighting in corridors, back-of-house areas, or outdoor covered spaces, which directly reduces infrastructure cost and maintenance overhead.

Technical Highlights:

• F2.0 Aperture + 0.055 Lux Specification: Translates to genuine color video in near-darkness. Stairwells, loading docks, parking structures lit only by exit signs will record usable footage without IR or external lights. Real money saved on lighting infrastructure in retrofit installs.
• Motorized Pan/Tilt/Rotate (−176° to +176° Pan, 0° to 64° Tilt, −90° to +90° Rotation): Broad directional coverage without gimbal mounts or post-install repositioning. Particularly useful in dense installations where mount points are fixed but viewing angles must be optimized after commissioning.
• Ø35.5 × 35.9mm, 30g Footprint: Fits into compact mounting scenarios—narrow eaves, tight corner mounts, or retrofit installs where space is constrained. Low mass means standard brackets suffice; no reinforcement required.
• 2MP, 1/2.8" CMOS, 3.6mm Fixed: Adequate resolution for license plate or face recognition at 20–30 feet in good light. Fixed focal length means no autofocus lag or zoom creep under thermal stress—key for 24/7 unattended installations.

Deployment Considerations:

• This lens is platform-locked to the PNM-7002VD. Do not assume cross-compatibility with other Hanwha models or third-party dual-sensor platforms without explicit manufacturer confirmation. Mechanical and electrical connectors vary.
• Motor control for pan/tilt/rotate is host-platform dependent. Verify the PNM-7002VD firmware supports motion commands before specifying motorized positioning in your design. If motion control is a requirement, confirm driver availability for your VMS or recording appliance.
• No onboard infrared illumination in the lens itself. If night-vision is required, rely on the host platform's IR capability or external supplemental lighting. The low-lux sensitivity helps, but does not replace IR for true zero-light scenarios.

Positioning: Deploy the SLA-2M3602D in multi-camera warehouse or retail surveillance where you need standardized, fixed-angle coverage across dozens of locations—predictable geometry, no zoom complexity, and the low-lux rating eliminates supplemental lighting in most interior spaces. Ideal for integrators seeking to reduce spare-parts inventory and simplify field commissioning across a regional fleet.
