That's a nice dashcam. I like that site, too. As I mentioned in another thread, I picked the SJ4000 action/dashcam. It's really an actioncam with dashcam features built-in.
I've been very happy with the quality of the video day and night. I need to shorten the recording cycle to 5 minutes. I currently have it set to 10 minutes and the files are about 1GB each.
I have it plugged into a switched outlet, so recording starts with the ignition, and stops when we open the doors. I could move it to a constant power outlet, but it doesn't have parking mode, so it would loop forever. It does have motion detection, and I wonder if that would work for driving and parking. I'll have to test that.
