Hanwha SLA-T4680V 2MP Pinhole Lens Module
The Hanwha SLA-T4680V is a compact 2MP pinhole lens module engineered for deployments where surveillance discretion is critical. This module integrates directly with the XNB-6001 system and delivers actionable image quality without the visual footprint of conventional security cameras. The design addresses a specific operational need: covert monitoring in retail loss-prevention, executive protection, and specialized security applications where visible cameras would either compromise aesthetics or alert subjects to surveillance activity.
Key Features
- 2MP Resolution at 60fps – Captures sharp, detailed images across 30 and 60 fps frame rates. The 60fps capability is especially valuable in dynamic retail environments or facilities with frequent foot traffic, where smoother motion capture improves both real-time situational awareness and investigative playback clarity.
- 4.6mm Pinhole Lens – The pinhole form factor is approximately the diameter of a pencil eraser, enabling installation through concealed ceiling tiles, wall cavities, or fake smoke detectors without triggering observer suspicion. This is the core advantage: psychological deterrence reduction means subjects often behave naturally, improving investigative value if an incident occurs.
- 73° Horizontal Field of View – Covers meaningful area (approximately 30 feet width at 20 feet distance) from a single covert mounting point. Wide enough to capture multiple aisles or room corners without requiring angle adjustments or multiple modules in smaller spaces.
- 120dB Wide Dynamic Range (WDR) – Handles high-contrast retail lighting — fluorescent aisle lights, direct window glare, shadowed corners — in a single frame. Without WDR, shadows would be black sludge and bright areas would blow out. At 120dB, the module balances detail across roughly a 1:1000 brightness ratio, so facial features and product shelf detail remain visible simultaneously.
- 0.06 Lux Low-Light Sensitivity – Operates clearly in dimly lit retail aisles during evening hours or after-hours monitoring scenarios. For context, 0.06 Lux is roughly twilight conditions; most conventional cameras degrade significantly below 1 Lux. This spec directly reduces the need for supplementary lighting, which could compromise cover.
- 8-Meter Cable Length (26 feet) – Extended cable simplifies routing from concealed lens placement to the XNB-6001 recorder, often installed in a separate secure location. Reduces the number of intermediate connectors and keeps wiring paths hidden in wall cavities or cable trays.
Integration & Compatibility
The SLA-T4680V (often searched as SLA T4680V) is purpose-built for the XNB-6001 ecosystem. Compatibility is guaranteed by design, so you avoid third-party combination risks. Cable termination, power delivery, and video transport are optimized for that platform, eliminating the adapter chains and configuration uncertainty that arise when mixing brands or mismatched form factors.
For IP camera deployments requiring concealed observation, this module sits at the extreme discretion end of the spectrum. If your deployment can tolerate visible equipment, standard bullet or dome cameras will offer more flexibility and easier integration across heterogeneous systems. However, if psychological deterrence avoidance or aesthetic preservation is non-negotiable, the pinhole form factor justifies the integration dependency.
Typical Deployment Scenarios
Retail loss prevention in high-end apparel or electronics — pinhole placement in ceiling tiles near vulnerable shelves captures shoplifting behavior without alerting organized retail crime groups to active surveillance infrastructure. Executive suites or sensitive conference areas where visible cameras would undermine confidentiality perception. VIP protection zones where discreet observation supports threat detection without compromising protected persons' awareness of surveillance. Facilities where insurance or compliance frameworks require monitoring but aesthetic or psychological impact must be minimized.
When to Choose a Different Module
If wider horizontal coverage is essential, consider a higher-resolution variant within the same family with a shorter focal length (wider angle lens). If your system requires ONVIF interoperability across multiple vendor platforms, the XNB-6001 dependency may be restrictive — evaluate modular camera systems with standardized connectors instead. If 8 meters of cable is insufficient for your installation, confirm available cable extension options with the manufacturer before committing.
Frequently Asked Questions
Q: Is the SLA-T4680V suitable for outdoor or weatherproof installations?
A: No. The pinhole lens module is designed for indoor deployments in controlled environments. It lacks weather sealing (IP rating not specified in evidence) and is not rated for outdoor or high-humidity exposure. Confine use to dry, climate-controlled retail, office, and facility interiors.
Q: What is the maximum distance the 8-meter cable can extend?
A: The module includes an 8-meter (26-foot) cable. Extended cable runs beyond that specification are not documented. Consult the XNB-6001 datasheet or contact the manufacturer to confirm maximum safe cable length without signal degradation.
Q: Can I use the SLA-T4680V with a system other than the XNB-6001?
A: The SLA-T4680V is designed for integration with the XNB-6001 system. Third-party integration is not documented in available evidence. Compatibility with other recorders or platforms is not supported in the current product information.
Q: What frame rate and resolution combination does the SLA-T4680V deliver?
A: The module captures 2MP video at up to 60fps. This combination ensures smooth motion rendering in fast-paced retail environments while maintaining the 2MP (1920 x 1080 equivalent or higher resolution format) detail needed for facial recognition and incident documentation.
Q: Does the pinhole lens support motorized focus or zoom?
A: No. The 4.6mm pinhole lens is fixed focal length with no motorized zoom or autofocus. Focus is manual during installation. Once positioned and focused, the lens remains static, which reinforces the covert form factor but limits field-of-view adjustment after commissioning.
Q: What is the low-light performance floor—can it operate in complete darkness?
A: The 0.06 Lux specification represents the module's minimum illumination under optimal sensor and lens conditions. Complete darkness (0 Lux) requires infrared illumination, which is not documented for this module. Confirm IR capability with the manufacturer if after-hours no-ambient-light monitoring is required.

The SLA-T4680V represents a specialized niche within surveillance — discretion-first monitoring where psychological deterrence reduction directly improves investigative value. The pinhole form factor is not a cosmetic choice; it's an operational asset. Most buyers exploring this module are already committed to covert observation; the question is whether the 2MP resolution, 60fps capability, and 120dB WDR deliver sufficient image quality to justify the XNB-6001 platform dependency. They do.
Technical Highlights:
- 2MP @ 60fps: Smooth motion capture in retail environments where shoplifters move deliberately to evade detection. 60fps playback eliminates jitter and frame skipping, making behavioral analysis more reliable than 30fps alternatives.
- 120dB WDR: Retail lighting is notoriously unforgiving — fluorescents overhead, window backlight, deep shelf shadows. At 120dB, the module handles roughly a 1:1000 brightness span. Without WDR, dark corners become unusable and bright areas wash out. This is the difference between investigative clarity and evidence ambiguity.
- 0.06 Lux sensitivity: Twilight-level performance. Most standard retail surveillance drops below 1 Lux into visible noise and color desaturation. At 0.06 Lux, evening-hour or after-hours monitoring remains clear without supplementary lighting—critical when cover must be maintained.
- 4.6mm pinhole form factor with 8-meter cable: Cable length allows the actual lens to sit 20+ feet away from the XNB-6001 recorder. This separation is often the deciding factor in retail deployments where the recorder must stay in a locked storage area while observation points span the sales floor.
Deployment Considerations:
- Fixed focal length, no zoom: The 73° horizontal FOV is wide, but you cannot adjust coverage after installation. If your pinhole placement misses a critical area, you'll need a second module or physical relocation. Plan mounting carefully.
- XNB-6001 dependency: This is not a generic ONVIF camera. Third-party integration is unsupported. If your facility runs a heterogeneous mix of recorders or relies on cross-platform VMS architecture, the SLA-T4680V creates a standalone island. Acceptable in pure-Hanwha environments; problematic in multi-vendor shops.
- No IR illumination documented: The 0.06 Lux spec assumes residual ambient light. Complete darkness requires external IR, which is not listed. If you need round-the-clock covert monitoring with zero ambient light, confirm IR capability before committing.
Position the SLA-T4680V in high-end retail loss-prevention operations, executive/VIP protection zones, and facilities where visible surveillance would trigger social or contractual friction. It is not a general-purpose camera; it is a deliberate choice to eliminate observer awareness. Deploy it where that trade-off justifies the platform constraint.
