So, after almost two years of known vulnerabilities existence Amcrest updated the firmware on some of their cameras. But for this camera line the firmware seems to go backwards. It was V2.520.AC00.18.R, now it's V2.420.AC00.18.R. Does anyone know why? Did Amcrest reuse the older firmware base from Dahua because it didn't have those vulnerabilities? Just curious.

We had the same question when we examined this last week. Interestingly, the Dahua patched firmware is 2.622.0000000.7.R but the
Amcrest patched one is V2.420.AC00.18.R. Certainly, any company can choose any method for how it increments/enumerates firmware but what Amcrest did here is strange.

@john-ipvm, would you happen to know which Dahua firmware can be used on these Amscrest cameras, if any?

I don't, we did not check loading or using Dahua firmware on Amcrest cameras.
