6-in-1 Video Output SDI Camera Module with High-Speed Imaging & Advanced Processing

The Lntech SNQ-3579T is a high-end camera module designed for integration into professional surveillance systems where image fidelity and performance are critical. It utilizes a 1/2-inch Sony IMX385 STARVIS™ CMOS sensor capable of outputting 1080p resolution at 120fps. Its defining feature is user-selectable video output across six protocols: AHD, TVI, CVI, CVBS, HD-SDI, and EX-SDI. Advanced image processing includes true 120dB Wide Dynamic Range (WDR), a sophisticated Defog algorithm, and 3D-DNR, making it a superior solution for demanding applications like traffic monitoring and perimeter security.

In-Depth Technical Analysis

1. Multi-Format Output & HD-SDI Switching
The module's output is configured for maximum flexibility. The desired analog format (AHD, TVI, CVI, CVBS) is selected via a dip-switch. The HD-SDI and EX-SDI digital outputs provide uncompressed signal options; switching between them is done via a specific OSD menu key sequence (3x Left + OK for EX-SDI, 3x Right + OK for HD-SDI).

2. Optical Performance & Sensor
The Sony IMX385 is a 1/2-inch optical format sensor with large 3.75µm pixels. This large pixel size is the primary factor behind its excellent low-light performance and high signal-to-noise ratio. It achieves starlight-level imaging (0.00008 Lux) through supporting DSS technology and Sens-Up frame accumulation (x64). Electronic shutter control ranges from 1/60s to 1/30,000s.

3. Image Processing & Enhancement

• Wide Dynamic Range (120dB): Utilizes multi-frame exposure processing to resolve detail in scenes with extreme contrast, far exceeding traditional WDR capabilities.

• Advanced DEFOG Algorithm: Implements digital image enhancement to mitigate atmospheric scattering caused by fog, haze, and mist, crucial for long-distance monitoring.

• 3D Digital Noise Reduction (3D-DNR): Employs temporal and spatial noise reduction techniques to suppress noise in low-light footage without sacrificing motion clarity.

4. System Integration & Control

• Motor Control: Integrated driver supports auto focus and zoom motorized lenses (e.g., 2.8-12mm, 6-22mm). Features comprehensive OSD control over focus modes.

• Comprehensive OSD Menu: Offers extensive parameter adjustment (Shutter, Gain, WDR, BLC/HLC, Privacy Masking, AF settings) accessible via coaxial control from compatible DVRs.

• Standard Integration: The 38x38mm size with standard mounting holes and clearly labeled connectors ensures easy integration into various housings and systems.
