I do not think so - that is NOT the same as mtd6 in an R0 camera.Good day! I found in my device mtd6 zone.
Is it possible to edit the area (fix), so that it is possible to install a multilanguage firmware, not a Chinese?
The fragment does look like it is XOR-encoded - but even after decoding it does not look anything like the mtd6 of an R0 series IP camera.
As I suggested earlier - the door station is very likely using a special security chip to hold the device-specific information such as region and language.
