I'm pretty sure I've come to the support section of the website and been able to download firmware updates. Now I'm trying to see if there is anything newer than what I currently have, and I can find no firmware at all for my 721S. I've been going around in loops and circles on the amcrest web site, but I'm not finding any firmware information at all, other than generic pages giving the impression firmware exists.
1. I am logged onto amcrest.com
2. I have tried with both Chrome and FireFox in case there's some odd JavaScript nonsense.
3. In the Setup > System > Upgrade panel on my camera, clicking the "Download the latest" and "Check Version" does nothing as far as I can tell.
