I want to make it absolutely clear that this is an unofficial post about the Fosscam SD2X which is the model that I currently have. Any information that is being presented is based on what I have done in order to fix any issues that I’ve had. Some of them may or may not work for you but it is always worth a try. You use this site/page at your own risk. I will always try to link to official site/page.
A general rule of thumb before doing any modifications you should back up
