Sorry, I should have been more specific.... While we had it, I'm positive it did not. That's why we forced a reboot. I do seem to recall reading from 522/625 users later that a s/w update added this....but I thought that my 522's did reboot daily.
I don't have them anymore so someone that actually does have a 522/625 will have to confirm whether they do or don't reboot nightly.
My 625 and 622 both do a nightly reboot, UNLESS they are recording something.
