Resolution is very good...Reviewed in the United States on July 14, 2020
but one of channel went bad in 3 months. I disconnected a power and re-connect as recommended by Vantrue support but it went bad again in a few hours. You can check from my photo that listed files and 2 of A channel video files are not normal and playback with only 2 channels instead of 3 channels. I requested a technical support again so I will update later based on how it goes.Updated on 7/28/20I had an issue with front camera that failed to display & record. I had to contact with customer service-actually I am having a long history with CS since I ordered OBD cable- then they sent me a new one to re-try it. They had to re-send another one since first replacement was nowhere on the way to carrier. The CS response is quite good and can see they are work for CUSTOMER so I change my rate from 3 to 5. Will keep update.
