Technical specifications for Lntech's SNQ-K3578. 1/2" Sony IMX385 sensor, 1080p60, 0.00008Lux. 32x32mm size. Switchable AHD/TVI/CVI/CVBS/HD-SDI/EX-SDI output, 120dB WDR, DEFOG. For compact OEM integration.
SNQ-K3578 (EN779+IMX385) Technical Overview
Compact 6-in-1 Video Output Camera Module for Space-Constrained Applications
The Lntech SNQ-K3578 is a high-performance, compact camera module designed for integration into professional surveillance systems and OEM equipment where board space is at a premium. It utilizes a 1/2-inch Sony IMX385 STARVIS™ CMOS sensor delivering 1080p resolution at 60fps. Its key feature is user-selectable video output across six protocols: AHD, TVI, CVI, CVBS, HD-SDI, and EX-SDI. Housed in an ultra-compact 32x32mm form factor, it includes advanced image processing such as 120dB Wide Dynamic Range (WDR), a Defog algorithm, and 3D-DNR, making it a superior solution for drones, compact housings, and embedded systems.
In-Depth Technical Analysis
1. Multi-Format Output & Switching
The module's output is highly configurable. The desired analog format (AHD, TVI, CVI, CVBS) and digital SDI format are managed through the OSD menu. The EX-SDI digital output provides an uncompressed signal option for compatible recorders.
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 (up to x32). Electronic shutter control is extensive.
3. Image Processing & Enhancement
- Wide Dynamic Range (120dB): Utilizes multi-frame exposure processing to resolve detail in scenes with extreme contrast.
- Advanced DEFOG Algorithm: Implements digital image enhancement to mitigate atmospheric scattering caused by fog, haze, and mist.
- 3D Digital Noise Reduction (3D-DNR): Employs temporal and spatial noise reduction techniques to suppress noise in low-light footage.
4. System Integration & Control
- Compact Integration: The 32x32mm size is a key advantage, allowing integration into the most space-sensitive designs without compromising on features.
- Motor Control: Integrated driver supports auto focus and zoom motorized lenses.
- Comprehensive Control: Offers extensive parameter adjustment via Coaxial OSD from compatible DVRs or via RS-485.
- Standard Connectors: Clearly labeled ports ensure easy integration despite the small size.
