Does anyone know if there is a program available to compare different binaries (in this case firmwares) to see the differences. Of course it would be nice if it would be aware of the ARM machine code, this would help to mask differences which are just due to different locations of the code (e.g. jump absolute jumps). Guess a program checking only the binary diff would not work good here...
Maybe it is possible with IDA or some plug-in?
Would be interesting to see the differences between similar camera, where one implements one feature and the other doesn't...
