Hi,
Quick update on the dashcam. I'm really impressed by the camera - the way it's installed also makes this such a usable feature. That said, one of the issues all dashcam users can suffer from is reflection from the front windscreen, particularly in sunny weather and at night.
To combat this, you can buy a 'circular polarizing lens' (CPL) filter to filter out polarized light, reduce reflections, enhance colors and increase contrast.
The one i bought was this one
here at £27.
Images below are not mine but having tried it, really pleased with the result and would highly recommend

Without CPL at the top and with CPL on the bottom - there is noticably less glare:
