A while back we were introduced to Pittasoft when we reviewed the BlackVue DR650S-2CH dashcam. Overall we were quite happy with the performance, but there were a few improvements we would have liked to see. When I recently heard the DR900S-2CH was coming out, I jumped on the chance to look at the new and improved device. The biggest improvement on paper is now the primary camera is capable of 4K resolution and the rear is 1080P.
