SNQ-6578 (EN778+IMX265) Technical Overview
Global Shutter Camera Module with SDI Output & Advanced Processing
The Lntech SNQ-6578 is a specialized camera module designed for integration into systems requiring high-fidelity imaging of fast-moving subjects. It utilizes a 1/1.8-inch Sony IMX265 STARVIS™ CMOS sensor featuring a global electronic shutter, enabling distortion-free capture of 1080p resolution at 60fps. Its primary video outputs are HD-SDI and EX-SDI, with an additional CVBS output for legacy support. Advanced image processing includes 120dB Wide Dynamic Range (WDR), a Defog algorithm, and 3D-DNR, making it an ideal solution for demanding applications like license plate recognition (LPR), traffic monitoring, industrial automation, and machine vision.
In-Depth Technical Analysis
1. Global Shutter Performance
The module's key differentiator is its global shutter. This technology exposes all pixels simultaneously, eliminating the "rolling shutter" effect (skew, wobble, smear) common in most CMOS sensors when capturing fast motion or under pulsed lighting (e.g., strobes, LED lights). This is critical for accuracy in LPR and industrial measurement applications.
2. Multi-Format SDI & Analog Output
The module provides HD-SDI (SMPTE 292M) and EX-SDI output for high-quality, uncompressed digital video transmission over coaxial cable up to 500 meters. The CVBS (700TVL) output offers a composite video fallback or monitoring feed. Switching between HD-SDI and EX-SDI modes is accomplished via the OSD menu.
3. Image Processing & Enhancement
-
Wide Dynamic Range (120dB): Utilizes multi-frame exposure techniques to resolve detail in scenes with extreme contrast, essential for traffic applications with headlights and shadows.
-
DEFOG Algorithm: Applies digital image processing to reduce the obscuring effects of atmospheric haze, fog, and light rain, improving clarity in poor weather conditions.
-
3D Digital Noise Reduction (3D-DNR): Combines temporal and spatial filtering to suppress noise in low-light footage while preserving detail and motion integrity.
4. System Integration & Control
-
Control Protocols: Offers comprehensive control via Coaxial OSD (from compatible DVRs) and RS-485 using Pelco-D and Pelco-P protocols. Baud rate is configurable from 2400 to 115200.
-
Additional Interface: Features a BT1120 digital video output port for direct raw data extraction, appealing for advanced embedded vision projects.
-
Standard Form Factor: The 38x38mm board with standard mounting holes facilitates easy integration into custom housings and systems.
