I apologize for bumping an old thread, but I wanted to ask before I order my opia2. This is the first premium dash cam that I will be ordering. I've had several budget cams and all but one has had problems. I figured I should spend the extra money upfront for a nice capacitor dash cam that will last me several years.No it's not required for standard switched ACC/Ignition on recording but is recommended if you want to safely record while away in parking mode.
