Hello, I have a DR600HW-HD installed in a work vehicle. I was able to connect with the app to set it up, view live video, etc. When I went back to review the recordings I find that it really downloads video back SLOWLY. It took about 2 minutes to get around 30 seconds of recording and then it froze. After several attempts I couldn't playback any entire clip and waiting around 2-3 minutes only got me 20-30 seconds of video. There would be no way to browse through recordings to find one of interest. Why can the live video stream so well and the recordings so poorly? Is the WiFi really only good for initial setup and live view? Looked to do a firmware update, but was confused by the website having one firmware file and the app suggesting another.
