Daytime, front camera video is awesome, really loving the quality when I was spot checking some files. The rear camera is crisp too, even though it's 1080. Haven't really checked night vision videos as much yet. Wiring was easy, and though I bought the fuse power kit, I ended up going for an OBD power cable from Amazon which worked great! Now for the quirks:
1. The unit's built-in wifi was basically non-functional for me. I sat in the car fiddling with it for almost 20mins and never could get a single file to download to my phone. It would just take forever. Finally gave up, took the microSD card out, and put it in a computer -- all files were immediately available. Never tried the wifi again.
2. Been using the camera for maybe a month now, and just experienced my first crash. Pulling time stamps from the video files, seems like it happened around noontime while the car was parked (one corrupted video file with that timestamp, followed by the next video right around the time I fixed it - a lapse of about 8hrs). Got the indication when the screen (normally off) was on and I saw what looked like vertical streaks instead of a front view. Pushing buttons didn't do anything so it seemed like the entire unit was unresponsive and showing garbage on screen. Had to power cycle the camera. The rear view is in a PIP window and, I noticed after the main unit power cycle, it came out black. So I ended up power cycling the rear camera too. After both power cycles, the video for both was showing in the screen again and things seemed to go back to normal.
