I'm on the fence about purchasing this product. I really like the features especially the set it and forget it aspect. I'm not looking to do action videos, but wanted something in the event of a traffic mishap. I've saw videos and it appears to artifact a lot and license plates are not very clear. Is there a new firmware that will address this issue or is it just a hardware limitation? I was also curious about the size and type of SD card that can be used with this system. My cars dashcam errors out unless a specific type of card is used.
