Introduction to Firmware Analysis of a Reolink IP Camera

I tried to read the 7 articles in one go and was impressed by both the illustrations and the way the author explains the whole process (I liked the illustration for submarine referring to U-Boot). I assume that this series is for beginners and not for experts. Am I right?

I would like to better understand the security implications of the Reolink device, I have definitely bookmarked this series. With the last chapter, however, I don't understand whether there will be a continuation or no real conclusion.
