Has anyone any idea whether I can use DS-2CD2347G1-LU firmware on the DS-2CD2347G3E-L , both are 4MP Colorvu turrets with the same specs but the DS-2CD2347G3E-L seems to be for the far east / middle east and are at least 50% cheaper to buy than in the EU/UK. I have 3 running perfectly back in the UK and just purchased another 2 yesterday, I am not really concerned if they can't use the firmware I just have plenty of time on my hands at the moment and there doesn't appear to be anything in any download portal that I can find .
