The instructions are fairly clear, if you've managed to create the file that's the hardest part - you just use the web interface to flash it - you just have to have some cunning with navigating the Chinese language menus!
Let me know if you can't find it and I'll take some screenshots...
Hi,
Just thought I'd add - I purchased two 'English' Hikvision DS-2CD2132 cameras from ebay - the Synology NAS just wouldn't communicate with them.
Having purchased and ran the patched firmware supplied by CBX (less than a few hours turn around) both are working fine!
Thank you!
