I'm having some Sentry issues and I can't figure it out. I'm not getting the recordings for Sentry events. I have an Anker USB with a san disk micro SD card that has worked fine in the past. This has apparently been going on a while but I never noticed until I pulled the drive and there were only a few videos. I have reformatted a couple of times and it still isn't working. Last night I got in my car and it said I had 2 sentry events. I hit the button and it brought up the viewer and no videos were there. To test, while driving I hit the dash cam button and it said recording. When I parked I hit the viewer and the video of the drive when I hit the button a few minutes ago was there, but no other Sentry clips. I've had the drive in for weeks so I know there were other Sentry events. It seems that it will record when I hit the button, but not when it is triggered automatically or when I actually need it to record. I get the notification that there were events in the car, but nothing saves??? Does anyone have any idea why this would be happening? Thanks for any tips, i've been trying to figure this out for a while.
