My thoughts exactly. I also noticed the HW4 has the ability to reduce flicker from headlights. You can see the difference is huge during the rear camera comparison. Overall, a nice improvement from the HW3 suite.The v4 videos look much more clear (both night and day) and color accurate. The nighttime views are much more "sunburst" in the v3 shots than the v4 shots. I wonder if that's due to the lens, or maybe the hardware is better at filtering out the spikes.
