Remember that Sentry videos are kept in a different folder than videos that are manually saved by using the Save function. This can cause some confusion when trying to find Sentry videos to match up with manually saved videos.Yes, I always have Sentry mode on as indicated by that red dot in the box I think. As soon as the accident happened, I went into the car and hit the download function but it still only started the recording after the impact. I definitely want to look into this more though to make sure that this situation does not happen again with the recording thing. I would encourage everyone to test their Sentry mode by parking, walking away and then coming back and reviewing to make sure it's recording. I have reviewed many recordings though (I'm a little paranoid about where I park so I review a lot) and have never run into this situation in the past where there has been lapsed video.
Man, I’m so sorry for your loss. Let us know how it goes?
