LN-802 (Sony IMX335) Technical Overview
High-Performance Camera Module for Demanding Surveillance Applications
The LN-802 camera module leverages the Sony IMX335 sensor (1/2.8-inch, ~5.14M effective pixels) combined with an advanced processing platform to deliver high-resolution video output, including 5MP (2592x1944) and 1440P@30fps. This integration provides a robust solution supporting True WDR for high-contrast scenes, 3D-DNR for low-light clarity, and optional POC for simplified installation. The module's IP67-rated metal housing and 40m IR range make it suitable for professional security, industrial, and commercial applications where reliability and image quality are paramount.
