I have an old DS-2CD2332-I that comes with 4.0.9 firmware and has "CCRR" in the serial number. The camera is dated some time in 2013. I would like to upgrade to a newer firmware version like 5.1.6 or 5.2.5. I wonder if I can upgrade it via the web UI or I should use TFTP. And is this a Chinese version even though it has CCRR instead of CCCH in the serial number?
Thanks for any help.
