Vortex Radar also compared the maximum bitrate of the three dash cams. Blackvue DR900S and Thinkware U1000 is only up to 25Mbps, while A129 Pro Duo is up to 50 Mbps, the high bit rate means the camera is able to capture smooth video even in high speed driving. Viofo A129 Pro Duo supports four bitrates options (Low, Medium, High and Maximum). High bitrate can make a better video quality.
