SNQ-38581F (EN781+IMX335) Technical Overview

6-in-1 Video Output 5MP Camera Module with Auto Focus & 120dB WDR

The SNQ-38581F is a high-end camera module engineered for integration into professional surveillance systems and OEM equipment. It leverages a Sony IMX335 STARVIS™ sensor to deliver 5MP resolution and superior low-light performance from a 1/2.8-inch optical format. Its defining characteristic is user-selectable video output across six major protocols: AHD, TVI, CVI, CVBS, HD-SDI, and EX-SDI. Advanced image processing includes WDR (120dB), Defog, and 3D-DNR, making it a robust solution for the most demanding security, traffic, and industrial monitoring applications.

In-Depth Technical Analysis

1. Multi-Format Output & Switching

The module's output is configurable via two methods: a DIP-switch on the control cable (SNQ-043) or a long-press of the confirmation button on another cable type (SNQ-034). This covers all modern analog HD formats (AHD, TVI, CVI), standard definition (CVBS), and digital outputs (HD-SDI, EX-SDI) for maximum integration flexibility. EX-SDI supports transmission up to 350 meters with appropriate cabling.

2. Optical Performance & Sensor

The Sony IMX335 is a 1/2.8-inch CMOS sensor with a 6.52µm large pixel size (post-binning for 5MP output), contributing to its exceptional sensitivity, achieving starlight-level imaging (0.00008 Lux). This is further enhanced by Frame Accumulation (Sens-Up) technology, which can be set from Off to X32. Electronic shutter control ranges from 1/25s to 1/12,800s.

3. Advanced Image Processing

• Wide Dynamic Range (120dB): Utilizes multi-frame exposure processing to resolve critical detail in scenes with extreme contrast, such as entrances with bright backgrounds.

• Advanced DEFOG Algorithm: Implements intelligent digital image enhancement to mitigate atmospheric scattering caused by fog, haze, and mist, ensuring reliable monitoring in adverse weather.

• 3D Digital Noise Reduction (3D-DNR): Employs temporal (frame-to-frame) and spatial noise reduction techniques to suppress noise in low-light footage, resulting in a cleaner, more usable image.

4. System Integration & Control

• Auto Focus Driver: Integrated driver supports varifocal motorized lenses. Features Auto/Manual focus modes and an INITIAL function for calibration.

• Comprehensive OSD Menu: Offers extensive parameter adjustment (Shutter, Gain, WDR, BLC/HLC, Privacy Masking, AF settings) accessible via coaxial control from compatible DVRs. Includes a hidden menu for setting factory defaults.

• Standard Integration: The 38x38mm size with standard mounting holes and clearly labeled connectors (POWER, IR-CUT, FOCUS, ZOOM, RS-485, SDI) ensures easy integration into various housings and systems.
