Updated review -- SatisfiedReviewed in the United States on December 9, 2017
I did a lot of research before deciding on this dash cam. I was very happy with it at first, in May of 2017, but I quickly noticed that park mode didn't work well. After a night of being in park mode, the software would completely lock up. I had to unplug it and let the short lived internal battery drain so that the device turned off (the on/off button wouldn't work when locked up). All was fine again after it shutdown and I plugged it back in, but park mode was useful for only around an hour before the device froze. Also, during the day, around a 75 degree day, this device would freeze or seemingly turn off (screen went blank and pressing the power button had no effect). It wasn't a hot day but the device was extremely hot, so I assume it was related to overheating. Picture quality, sound quality, and front and rear cameras are all good. If reviewing only on those aspects my rating would be higher, but half the reason I bought this was for park mode, plus what seems to be an overheating problem warrants only 1 star. I wouldn't give it zero stars, if that was an option, because I still occasionally plug it in and run until I park or it overheats, whichever happens first.EDIT: I had updated the firmware when I first bought the camera but there have been a couple of newer versions since then. I updated the firmware to the latest one a couple of days ago, which was made available around two weeks ago, and the camera works much better. The device still gets hot but it no longer shuts down because it's too hot, and park mode works all night. Also, it auto-switches between park mode and live mode as it was supposed to do. I changed it's rating from 1 star to 3 stars. After more use, I may up the rating again. I wish its low-light recording was better, but there aren't many cameras that record well in low-light without using actual night-vision technology. Thank you, Vantrue, for responding to my rating, I would not have tried updating the firmware again, otherwise.
