 There are many hackers who produce modified versions of the original firmware. In general they distribute the original firmware patched in several places, mainly to customize framerates, exposure parameters, etc. There are many hackers who produce modified versions of the original firmware.

 +I created a custom firmware to improve some video codec settings and to improve image quality (mainly color balance and saturation). You can find it here: **[[sjcam-8pro-custom-firmware]]**.
  
 Generally there is **no access to the source code**, so **patching the firmware binary** is a rather delicate task, requiring to know the exact offset of the data into that **specific version of the firmware**, the structure and the lenght of the data and eventually how to **update the embedded checksums**. SJCAM does not facilitate the task, because it distribute different versions of the firmares marked with the same version number. Generally there is **no access to the source code**, so **patching the firmware binary** is a rather delicate task, requiring to know the exact offset of the data into that **specific version of the firmware**, the structure and the lenght of the data and eventually how to **update the embedded checksums**.

 The interface is based on **JSON messages**: you can exchange them over the WiFi connection as the official app **[[https://play.google.com/store/apps/details?id=org.jght.sjcam.zone|SJCAM Zone]]** does between the Android device and the camera. You can also **connect a PC** to the camera via WiFi and use any programming language supporting TCP sockets. The interface is based on **JSON messages**: you can exchange them over the WiFi connection as the official app **[[https://play.google.com/store/apps/details?id=org.jght.sjcam.zone|SJCAM Zone]]** does between the Android device and the camera.
