Getting the hang of it
Something has always been a mystery to me

I have 2 x 2CD2335FWD-i/G cams, both are Uk official cams from a reputable Uk dealer

Both running exactly the same FW V5.5.51 180326, same Encoding Version, same Web version

One has an upgrade button available next to the FW version on the cams UI, the other does not ??

always been a mystery to me, any you guys seen this before ??
