Oh and yes, for the first camera:

Hello there!
I recently bought two cameras DS-2CD1043G0-I, first one came with FW v5.5.800 build 210628, the second one came with v5.7.0 build 210908.
I've tried to look for the second FW on the internet, but i failed.
I found that this camera is the E8 HW version, which led me to the firmware...
