I've been happy with this one from Amazon: Rexing V1 3rd Generation 4K UHD WiFi Car Dash Cam 2.4" LCD 170° Wide Angle Dashboard Camera Recorder with WiFi, 16GB Card, G-Sensor, WDR, Loop Recording
Tapped into the driver's door fuse panel so it powers on with the key turned to accessories/on. It mounts behind the rear view mirror and is basically out of sight and out of mind. The video is pretty impressive. Haven't checked out too much night time video yet though. We got a dual, front/rear, version for the wife's Jeep which is awesome with the hatchback window.
