dashcam arrived today
It's actually pretty decent, about what I expected, not sure about the "motion detection" though, that's just a weight inside it that moves around like a cheap pedometer, but since the car's a manual I'm sure my poor shifting is enough to get the weight moving and start the recording. Don't think it'd work well in my Avalon though, that thing's like driving a comfy sofa but it accelerates and handles about as well as a sofa does too
the night vision is reasonable, doesn't reflect off the windshield like I was afraid it would, but you don't really need the night vision as long as the head lights are on. I don't see a way to turn off the night vision feature but it seems to record in color even with the night vision on so it doesn't matter.
I'll try and put some videos on youtube later this week
