8.29-Megapixel Ultra-HD Camera Module for Professional Integration

The Lntech LN330-4K30F represents a high-fidelity imaging solution engineered for applications demanding superior resolution and professional interfacing. This module incorporates a 1/1.8-inch CMOS image sensor capable of capturing native 3840x2160 pixel imagery at 30 frames per second. It provides dual-stream output via 3G-SDI (EX-SDI compliant) and HDMI, facilitating integration into broadcast, medical, and industrial vision systems. Advanced control via RS-485/LC-ARS and an extensive On-Screen Display (OSD) menu allows for precise calibration to specific operational requirements.

Engineering Analysis

1. Sensor Architecture and Performance
The module utilizes a high-quality 1/1.8-inch optical format CMOS sensor. With 8.29 million effective pixels, it provides true Ultra-High-Definition resolution. The progressive scan system eliminates motion artifacts, delivering a clean, sharp image suitable for both dynamic live scenes and detailed inspection tasks.

2. Output Interface Configuration

• 3G-SDI Interface: Supports EX-SDI (3G-SDI Level B) for 2160p25/30 transmission, ensuring compatibility with broadcast infrastructure. In 1080p mode, it operates as a standard HD-SDI/EX-SDI source.

• HDMI Interface: Provides a direct digital video feed, supporting 4K (2160p) and 1080p resolutions, ideal for local monitoring and recording.

• Output Synchronization: Both interfaces can be active concurrently, providing dual independent video feeds.

3. Optical and Low-Light Capabilities
Equipped with a standard C/CS lens mount, the module supports a wide range of industry-standard lenses. The integrated drive circuit supports auto-iris lenses for optimal exposure control. The exceptionally low read noise of the sensor enables a minimum illumination of 0.33 lux in monochrome mode with the ICR filter engaged.

4. System Integration and Control Logic

• Control Protocol: Selectable between RS-485 and LC-ARS, allowing compatibility with various PTZ controllers and system processors.

• OSD Menu System: A full-featured menu provides access to critical parameters: Exposure (AES, AGC, Shutter), Image Processing (DNR, Defog, Sharpness), and System Settings (Language, Reset).

• Environmental Hardening: The module is rated for continuous operation from -20°C to +80°C, ensuring stability in uncontrolled environments.
