I upgraded my M-series NVR (DS-7716NI-M4 / 16P) firmware from v4.61.420 to v4.63.000, and since then my motion detection email alerts no longer have images in them, despite the settings for them remaining in place (and worked fine in previous firmware versions). The motion detection emails now include one jpg attachment (instead of previous three), but it seems to be in some corrupt format that cannot be opened.
Furthermore, when I try to roll back and reinstall the v4.61.420 firmware, I get an error saying that the NVR is out of flash memory and I should reboot and retry; but a reboot does not address this issue, and therefore I seem unable to downgrade back to v4.61.420.
Are these known bugs already, or new ones that Hikvision should be made aware of?
