Technical specifications for Lntech's SNQ-33581. 1/2.8" 5MP Sony IMX335 sensor, 1944P/1440P/1080P output. Switchable AHD/TVI/CVI/CVBS/HD-SDI/EX-SDI, 120dB WDR, DEFOG, AF. For OEM and professional integration.
5MP High-Resolution Camera Module with 6-in-1 Video Output
The Lntech SNQ-33581 is a high-performance camera module engineered for surveillance systems where superior image detail and integration flexibility are paramount. It utilizes a 1/2.8-inch Sony IMX335 CMOS sensor capable of outputting up to 5MP (2592x1944) resolution at 20fps, alongside standard 1440P and 1080P streams. Its defining feature is user-selectable video output across six industry protocols: AHD, TVI, CVI, CVBS, HD-SDI, and EX-SDI. Advanced image processing includes 120dB Wide Dynamic Range (WDR), a Defog algorithm, and 3D-DNR, making it a superior solution for demanding applications like city surveillance, traffic monitoring, and high-detail security.
1. Multi-Format Output & Switching
The module's output is highly configurable. The desired analog HD format (AHD, TVI, CVI) or CVBS is selected via a dip-switch (SNQ-043 cable). The digital outputs (HD-SDI and EX-SDI) are switched via a specific OSD menu key sequence. An optional POC (Power over Coax) add-on board can be attached to enable 48V power and data transmission over a single coaxial cable for SDI modes.
2. Optical Performance & Sensor
The Sony IMX335 is a 1/2.8-inch optical format sensor capable of 5MP resolution. This high pixel count allows for exceptional detail capture, making it suitable for applications requiring identification or digital cropping (e.g., electronic PTZ). It achieves starlight-level imaging (0.00008 Lux) through supporting DSS technology and Sens-Up frame accumulation (up to x32).
3. Image Processing & Enhancement
Wide Dynamic Range (120dB): Utilizes advanced multi-frame exposure processing to resolve detail in scenes with extreme contrast, essential for traffic and entrance monitoring.
Advanced DEFOG Algorithm: Implements digital image enhancement to mitigate atmospheric scattering caused by fog, haze, and mist, crucial for reliable outdoor performance.
3D Digital Noise Reduction (3D-DNR): Employs temporal and spatial noise reduction techniques to suppress noise in low-light footage while preserving critical image detail.
4. System Integration & Control
Motor Control: Integrated driver supports auto focus and zoom motorized lenses. Features comprehensive OSD control over focus modes (Auto/Manual/One-Push).
Comprehensive Control: Offers extensive parameter adjustment via Coaxial OSD from compatible DVRs or via RS-485 using standard protocols.
Standard Integration: The 38x38mm size with standard mounting holes and clearly labeled connectors ensures easy integration into various housings and systems.
