You're doing this remotely to an NVR in Oz?
Ballsy or what??
Yep. Just did it 10 minutes ago. Upgraded from 3.4.2 to 3.4.91. Thankfully the NVR rebooted. It did ask me to upgrade WebComponents, which I did without a problem. My HikVision cameras are recognized. The timeline still shows continuous recording on the top line in blue with no motion in red underneath. Maybe I need to go into the settings and retweak things. Or maybe just the historical stuff on the old firmware doesn't show. I'll keep everyone posted, as this was the sole reason for my upgrading the firmware, so that I could see motion over the web interface when recording continuously.
