Engineering Overview
The Lntech 2971R is a high-integration Camera Engine Board designed for professional HD surveillance solutions. This model shares the identical feature set and processing platform with the standard 2971 but is engineered on a more compact 38.0mm x 32.0mm PCB, catering to space-constrained industrial designs without compromising performance.
Core Technological Components
- Imaging Core: Utilizes the Sony IMX291 STARVIS CMOS sensor, renowned for its exceptional sensitivity and low-light performance due to its large 2.9μm pixels.
- Signal Processing: Based on the advanced K9ATCC platform, delivering full 1080P resolution and supporting high-frame-rate capture up to 120fps.
- Output Flexibility: The board can be configured to output one of six industry-standard signals (EX-SDI, AHD, TVI, CVI, CVBS, HD-SDI), providing unmatched compatibility for OEM designs targeting diverse markets.
- Motorized Lens Drive: Includes dedicated drivers and control logic for auto-focus (AF) and zoom motors, enabling feature-rich camera designs.
Advanced Image Intelligence
The integrated DSP delivers a suite of professional-grade image enhancements:
- Ultra Wide Dynamic Range (WDR): Manages high-contrast scenes effectively.
- 3D Digital Noise Reduction (3D-DNR): Significantly reduces noise in low-light conditions.
- Defog (DE-FOG): Algorithmically improves contrast and detail in foggy/hazy environments.
- Frame Integration (Sense-Up): Enhances sensitivity in extreme low light.
Integration & Control
Control and configuration are achieved through:
- Coaxial OSD: Allows full menu access and auto-focus control via compatible DVRs (e.g., Dahua).
- RS-485 Interface: Provides for external PTZ control or integration into larger systems.
