I apologize for my late response and thank you for all of your patience while waiting for a reply. I understand how frustrating your situation must be, and I would love to help however I can. Do you still need assistance?
Your new devices have not been around for 60 days on the account. You aren't going to get previous footage on a new camera. It will only record events if it fits that device's settings and category.
Just checking in to see if you still need assistance with this issue. We'll leave this topic open for another 24 hrs in case there are any follow up questions or comments. Please let me know if you need further assistance.
