BlackVue Wi-Fi DR500GW-HD Car Black Box/DVR Recorder
These cameras are awesome. The detail that they capture is amazing and there isn't any lag either, its completely able to keep up with the speed of the car. It's actually not very noticeable either despite its size, I asked a lot of my family members before i even told them i had them installed if they could see them. Most had no idea that it was there.
