Lntech SNQ2971T 2MP Camera Module with 6-in-1 Output Auto Focus and 0.00008 Lux Low Light Sensitivity

The Lntech SNQ2971T is a flexible camera module designed for integration into professional surveillance systems and OEM equipment. It offers a choice between two high-performance Sony STARVIS™ sensors – the IMX307 or IMX327 – both delivering superior low-light performance and full HD resolution from a 1/2.8-inch optical format. Its key feature is user-selectable video output across five major protocols: AHD, TVI, CVI, CVBS, and EX-SDI. Advanced image processing includes WDR (120dB), Defog, and 3D-DNR, making it a versatile solution for demanding security applications.

1. Multi-Format Output & Switching
The SNQ2971T's primary advantage is its configurable output. The desired analog format (AHD, TVI, CVI, CVBS) is typically selected via a dip-switch on the associated cable. The EX-SDI digital output provides an uncompressed signal option for compatible recorders and longer-distance transmission (up to 500m).

2. Optical Performance & Sensor Choice
The module offers a choice between two renowned Sony sensors:

• Sony IMX307 & IMX327: Both are 1/2.8-inch back-illuminated CMOS sensors with 2.75µm pixels, known for their excellent balance of performance, sensitivity, and value. They achieve starlight-level imaging (0.00008 Lux) through advanced pixel design and supporting image processing (Sens-Up frame accumulation). Electronic shutter control ranges from 1/50s to 1/60,000s.

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

• Auto Focus Driver: Integrated driver supports varifocal motorized lenses. Features Auto/Manual focus modes and One-Push AF.
• Comprehensive OSD Menu: Offers extensive parameter adjustment (Shutter, Gain, WDR, BLC, Privacy Masking, AF settings) accessible via coaxial control from compatible DVRs.
• Standard Integration: The 38x38mm size with standard mounting holes and clearly labeled connectors (POWER, VIDEO, KEY, IR-CUT, FOCUS, ZOOM, RS-485) ensures easy integration into various housings and systems.
