Got a chance to calibrate and test the Avin Avant-4 DDVR-2 camera system Advanced Driver Assistance Systems (ADAS) app. The lane departure and collision avoidance work really good but I had to turn the sound notification off as some sweet Chinese lady was screaming at me.
I hope future software releases will allow for English and the ability to choose normal beep notifications.
