Hanwha SLA-T4680VA 4.6mm Pinhole Lens Module

Hanwha SLA-T4680VA 4.6mm Pinhole Lens Module

The Hanwha SLA-T4680VA is a compact 2MP pinhole lens module engineered for discreet, high-performance surveillance in professional security applications. Designed for covert monitoring in sensitive environments, this module delivers sharp imaging with minimal visual footprint while maintaining exceptional low-light performance and precise field coverage.

Key Features

• 2MP CMOS imaging sensor for sharp, detailed video capture
• 4.6mm fixed focal length with 73° horizontal field of view
• 0.06 Lux minimum illumination for superior low-light performance
• F2.5 maximum aperture for enhanced light gathering
• Compact pinhole design for discreet installation
• RJ12 connection for seamless integration with compatible systems
• Durable metal and plastic construction
• Lightweight at 321g with minimal dimensions (W30 x H27.9 x D45mm)

Technical Specifications

The SLA-T4680VA utilizes a 1/2.8" 2MP CMOS sensor capable of operating in extremely low-light conditions at 0.06 Lux with F2.5 aperture and 1/30 second shutter speed. The 4.6mm fixed focal length provides a 73° horizontal, 39° vertical, and 85° diagonal field of view—ideal for monitoring specific areas with precision rather than broad coverage. The F2.5 maximum aperture ratio ensures optimal light transmission in dimly lit environments. Fixed focus control eliminates mechanical complexity and potential failure points, while the RJ12 connection provides direct integration with Hanwha's compatible surveillance systems.

Build & Installation

Constructed from a combination of plastic and metal materials, the module weighs only 321 grams and measures just 30mm wide, 27.9mm high, and 45mm deep—enabling installation in tight spaces and through standard pinhole penetrations. The compact form factor makes it virtually undetectable in professional environments, while the robust construction ensures durability for continuous monitoring applications.

Applications

The SLA-T4680VA is ideal for covert surveillance in banks, offices, retail environments, and other sensitive locations where discreet monitoring is essential. Its low-light capability makes it suitable for entry points, hallways, and areas with inconsistent or minimal illumination. The focused 73° horizontal field of view works well for monitoring specific zones rather than panoramic coverage, making it cost-effective for targeted security deployments.

System Compatibility

The module integrates seamlessly with Hanwha's professional surveillance infrastructure through its RJ12 connection, ensuring reliable signal transmission and compatibility with compatible Hanwha recording and management systems.
