Just thought I’d bump this back up with some more thoughts on the DR400G HD I have.
Initially the video seemed really clear

After a while the video starts getting cloudy

Initially I thought this was just a dirty lens, so I wiped it up and the windshield in front of the it, but it did not seem to help.
Some googling lead to people complaining that it was due to overheating issues and that they got it replaced while in warranty. Mine is well out of warranty unfortunately, so that was out of the question.
I had been contemplating getting a new dashcam, when someone suggested cleaning the inside of the lens. I was a bit skeptical since I didn’t see how dirt and crud could get inside there (The lens seemed pretty sealed up). But it seems like a few people have reported success doing this.
Gonna give it a shot later today and I’ll report back. Seems pretty easy other than accidentally getting dirt on the sensor itself.
