 +Edge2 CAM3 support **4K@60fps** record. If your **hardware version is V13 or later**, the **CAM2** also can support **4K@60fps** record. 
 +
 +**Check Hardware Version**
 +```shell
 +$ cat /proc/cmdline
 +```
 +V13 or later version will show like ''hwver=EDGE2.V13''.
 +
 +Due to the different hardware versions, **CAM2 is set to 4K@30fps by default**. This is for compatibility with V11 or V12 hardware versions to 
 +ensure proper operation. If your device supports 4K@60fps, you can enable this mode by adding an overlay node ''cam2-4lane''.
 +
 +
 +Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=cam2-4lane''.
 +
 +About IMX585 and IMX678, the two cameras were disabled by default. So V11 or V12 hardware version should replace ''cam2-4lane'' by ''imx585'' or ''imx678'':
 +
 +Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=imx585'' or ''fdt_overlays=imx678''.
 +
 +
 +V13 or later hardware version should be set ''imx585-cam2-4lane'' or ''imx678-cam2-4lane'':
 +
 +Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=imx585-cam2-4lane'' or ''fdt_overlays=imx678-cam2-4lane''.
 +
 +You need to reboot the device to take effect.
