dan732 0 Posted July 5, 2014 Just wanted to share this I did a firmware upgrade on DS2CD2032-I camera from 5.0.2 to 5.1.2 Old serial number DS-2CD2032-I20131218CCRR446005038 After upgrade serial number DS-2CD2032-I20131218CCCH446005038 Somehow the firmware changed the region of the serial number from RR to CH I assuming the CH stands for China And yes, this was a china cam I just thought it was strange to see part of the serial change because of a firmware update.
