Review on J Junsun 10 Inch Mirror Dash Cam W/ Front & Rear 1080P, 170° Wide Angle View + Backup Camera, G-Sensor Parking Monitor & Night Vision by Kevin Schnitzer

Works great for 6 months, now constantly freeze up during hot day. I've tried to format and even use a brand new Samsung SD card but no luck. Sometime the mirror reboot itself and looping non stop. I have to disconnect power to stop it. We have 2 units, the other one has no problems.Update: Sept/6/19the second unit (Installed on other car) has failed the same couple days ago as the weather has reached 95 degrees in Orlando. I've disconnected the power supply and drain the internal backup battery completely to stop the annoying frequently reboot sound.As a side note: The first unit was failed almost 2 months ago. After the initial contact email back and forth several times with Junsun's tech support to troubleshoot the issues. I've not heard from them anymore once I asked how to start a claim under warranty. So basically, their 1 year warranty is not exist, buy at your own risk. Sadly, it was a nice dash cam with lots of potential at a reasonable price but short live.
