Okay here are what i have found so far from install and a short drive to the car wash.
1: where the rear camera plug in i think that would have been smarter if that plug was where the SD card is located, or at least on the top "side" of the main camera.
I have the camera installed on the left side of the dotter area in front of my rear view mirror with the camera to the left of the mount, this mean the micro USB for power come down from the headliner above and into the mount ( good ) but then the wire for the rear camera is on the bottom side of the main camera and i have to route it around the end to not block the LCD screen or the lens on the other side of the camera body. ( will update with pictures later today )
2: the file structure on the memory card are a little confusing, the video clips are bundled 2 and 2, but it is not the 2 video clips with the same time stamp.
If you select the "A" clip then the corresponding "B" clip are the "B" clip in the two video-clips below ( groups of 2 video-clips being split up by a text document with GPS data i assume )
3: as i set off from home the camera dident record much and the rear camera footage was upside down, but after i parked at gas station and then drove to the back of it to wash my car, after that all the rear camera footage are the right side up for the remainder of my little drive.
I think rear camera flip is set to off. but it is like camera have to be restarted a few times before it understand this.
I have the rear camera mounted upside down, and i must say one would thing this camera was made for my car and the magnet i have on the rear hatch, fits like a glove
4: The LED's on the camera are very weak, totally impossible to see on this partly sunny day, but even in the shade of a building i cant see the light in them.
5: Also got memory error on the 128 Gb U3 Toshiba card i use for testing, but after in camera format it seem to work good.
6: I seem to have the left side of the front camera a little out of focus, but i have captured a lot of plates as i would expect on a sunny day like this ( thin high cloud cover )
will have to see if i have not cleaned the lens good after i remover protective film on it.
Rear camera appear to have good focus all around.
7: i tried to make a event recording using the little remote button, and when i pressed it the camera LCD did come on for a second and then dimmed again, but i cant seem to find that event recording on the memory card, but it was also on start of my drive where camera did not record much, will retry this again later tonight.
Conclusions:
I threaded the rear camera wire down the left A-pillar to the floor, then out back and up the C- pillar to the roof, and then across the rear of my headliner to the middle of the rear window where camera is placed.
It appear to me with my little 5 door car, that if you have a larger sedan or maybe a station-wagon then the original wire will have to go the direct route over the headliner to reach out back.
will upload two 3 minute clips ( front and rear ) and then update this post soon.
