 ===== Introduction ===== ===== Introduction =====
  
-This document mainly introduces MIPI Camera. The document is divided into two parts,The first part of the document describes how to connect. The second part introduces How to record video via Gstreamer and test your camera under Ubuntu.+This document mainly introduces the usage of [[https://www.khadas.com/product-page/os08a10-8mp-camera | OS08A10 MIPI Camera]].

-===== Video Node =====+===== Identify VIM4 Version =====
  
-The video node for MIPI camera is ''/dev/video50''.+<WRAP important >
  
-===== Record Video via Gstreamer =====+There are two versions of **VIM4**, they are **VIM4** and **New VIM4**, as they have different ISP IP core, so the usage of MIPI camera is also different, 
 +please follow the documentation to identify your VIM4 version and choose the right documentation for your VIM4.
