No, the scheduled reboot does not survive a system crash on my 2530.
When it crashes, which is once about every 1 or 2 weeks, for me it does not respond to the local url or any apps.
And it will stay crashed for longer than a week, ( or at least until I unplug it and plug it back in ).
If you are still having the problem with your 2530 not self rebooting,
then I would recommend getting a wifi smart plug or a simple outlet timer for this type of camera.
Its not a perfect solution, but a temp fix until Dlink can update their firmware so it works. (Hopefully)
( Just info, my dcs-2530L is fw 1.03.01 , hw A , agent 2.2.0-b09 .)
