If the doorbell lost its connection to WiFi then I’m pretty sure it can only store about an hour’s worth of footage.Then it recorded for as long as the battery held up, and you're right--they have more video. I hope it's better than my inner pocket or countertop.
Do you suppose the image/person that LE said was captured "from a camera" at 2:12 was from the disconnected doorbell camera?
The motion detected at 2:12 was reportedly from another camera inside the house.
