Last night, July 4, motion detector did not get me up walking up/down driveway looking at fireworks.

I checked this morning and there was no video of me walking up and down driveway.  Usually the camera picks up anyone getting the mail, the mail man, the garbage truck, etc.  Why would it miss me out there for 20-30 minutes?  The battery is a little low, 20%, would that be it?

I find the sensitivity for the day to be too low for night. I run a schedule that has day and night modes. The day mode has camera sensitivity between 85-95 but the night mode has all cameras at 100
Battery around 20% shouldn't affect it functioning
The other possibilities are that your internet was down or the Arlo was offline for a number of reasons during this time
