Yup, it overwrites. I think nearly all dash cams do this. However, there is a useful feature that allows you to select a segment of video on the cam itself (with the little screen) and lock it. This will prevent just that clip from being overwritten or erased inadvertently.bootymac wrote:Do you know what will happen when the memory card is full? I'm hoping it'll continually overwrite old footage so you can just leave it alone until you need it (hopefully never)
Also, the camera allows you to make each video clip 1, 3, or 5 minutes long or have the whole recording be one clip. With the 16 GB MicroSD card, the record time is roughly 3 hours at full resolution.
Another thing to note:
It records very well during the day. At night, it's decent but that's with traffic and street lights. On dark roads with nothing but the headlights, it does not accurately capture what your eyes can actually see. For example, last night when I was driving on my favorite road through the woods, a young fox crossed the road in front of my car. The fox was illuminated by my LED high beams above the HID low beam cut-off.
When I viewed the footage later at home, I could not see the fox at all despite finding the segment in the video where I slowed down for it.
In this regard, it's much like any other camera that has a hard time recording low light conditions when a bright light is present (low beams). Perhaps the recording mode can help as I've only tested things in Auto mode, but I'm not that hopeful. However, it's not like it matters for the purposes of having a dash cam.
