 +===== Identify VIM4 Version =====
  
-===== VIM4 =====+<WRAP important >
  
 +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.
  
-==== Video Node ==== +</WRAP>
