I am looking to spend up to $500 on the best dual channel setup. By best, I mean most featured and highest quality. Right now I am leaning towards the Panorama X2 as it has 1080p front and rear with a lot of working options (motion detection, etc.). Is there anything better? I looked at the BlackVue dual channel setups, but I feel as though they are inferior aside from more discrete? (720p rear)
