Fixed 3.7mm Lens 5MP Mini Camera IP67 Lntech LN-331 (781+IMX335)

Technical datasheet for Lntech's LN-331 5MP. 1/2.9” Sony IMX335 STARVIS, 1440P@30fps. 39x39mm IP67 metal housing. POC support. Features WDR, 3D-DNR. For OEM and professional integration.

The Lntech LN-331 (5MP) is a high-performance, ultra-compact camera module engineered for OEM equipment and professional surveillance systems where high resolution and small size are critical. It utilizes a 1/2.9-inch Sony IMX335 STARVIS CMOS sensor coupled with the 781 series signal processing platform to deliver 5-megapixel resolution and 1440p output at 30fps. Its key feature is support for Power over Coax (POC), simplifying system integration. Housed in a resilient IP67-rated metal enclosure measuring just 39x39x31mm, it is designed for reliability in demanding environmental conditions.

The module's 1/2.9-inch Sony IMX335 sensor is a key differentiator. As part of the STARVIS series, it is optimized for high sensitivity and excellent signal-to-noise ratio, providing superior low-light performance alongside its high 5-megapixel resolution. The 781 processor efficiently handles the high data rate and advanced image processing tasks.

• Power over Coax (POC): This optional functionality allows for transmission of power and video over a single coaxial cable, significantly reducing wiring complexity and installation time for system integrators. This is a critical feature for compact and discreet installations.
• OSD Control: All camera functions, including image settings, Motion Detection, and Privacy Masking, are configurable via an On-Screen Display menu accessible through the coaxial connection on compatible DVRs.

• Wide Dynamic Range (WDR): Enhances image detail in scenes with simultaneous bright and dark areas.
• 3D Digital Noise Reduction (3D-DNR): Applies both spatial and temporal filtering to suppress noise in low-light conditions, resulting in a cleaner image.
• HLC/BLC: Highlight Compensation and Backlight Compensation modes address specific over-exposure scenarios to improve target visibility.

The camera's chassis is constructed from milled metal providing superior durability, EMI shielding, and thermal management. The IP67 ingress protection rating certifies it is completely dust-tight and protected against temporary immersion, making it suitable for harsh outdoor environments.
