Here are the pics of the cam installed inside the car - sorry for the crap quality - was using missus' iphone in the basement car park.
Front cam from inside
Rear cam from inside
Rear cam from outside - my car is slightly tinted, but really the rear cam is barely noticeable even with the recording light unless you look closely.
Front cam from outside - this one is quite noticeable if you leave the recording light on and if you don't cover the silver part of cam with some black tape or something.
And here are some sample vids I took:

Some of them were taken either at night or at less than optimal condition - ie. raining at night. Considering we don't have rear rain wiper, raining = pretty much forget about rear footage as the rain drops smear the whole screen.
I don't think I've uploaded all of them in HD, so you might want to check Youtube for other sample vids. But at least you can sort of see how it looks like in the 86.
Overall video quality, it will be good enough to determine who's at fault when you have accident, but the bitrate and quality is not sufficient to record say: car coming fast from opposite direction and slightly swiped the side of your car (but I haven't seen any dashcam that can do this).
But for things like proving someone cutting your lane, bump you from behind, doing retarded thing in front of you, it will do the job fine.
Regarding the installation, there is no visible wiring running across from front cam to back cam - was installed professionally.
I was just looking at the website and looks like they have new one with all black cam, which should be less noticeable.
