on the left is 720 setting the right is the 1080 setting:
Not sure how evident it is in the picture, but there is significantly more clarity in the 1080 video playback. the 720 is very "grainy" and edges are not sharp, whereas the 1080 playback has crisp corners and the colors are sharper.
Is it possible they have changed the cmos sensor in this inexpensive camera to one capable of 1080?
I may have to get the precision screwdrivers out....

After seeing how the pictures posted, I can certainly say they are not representative of the difference between the two. it is a much more evident difference than those pictures show.
When my G1W-C gets here, I'll mount them both in the window and go for a drive for a comparison seeing as the G1W is a known 1080p camera....

As requested, here is the auction I used:
http://www.ebay.ca/itm/221504340942
**************************************************************************************************************************************
initial look seems that it's not a 170 degree FOV. A quick and dirty bit of trig makes it more like 90 degrees.
Quite a far cry frm the 170 as advertised in the auction.
I'll have to do a more detailed measurement to be able to say for sure....no time for that right now though.
I'l get to it sooner or later....
**************************************************************************************************************************************
Downloaded mediainfo and had a look at the 720 and 1080 files info:
Left is 1080, right is 720.
10 Mbps for 1080, 14 Mbps for 720.
I wonder if my Lexar 32 GB class 10 card is helping that rate out a bit? Dunno, not my area or knowledge....
Both are close enough to 30 Fps for me to call it 30 Fps.

Curiosity got the better of me and I removed the back case.

So, googling the CMOS sensor confirms it is only capable of 720.
Going to look up the A10 now....
***********************************************************************************************************
A10:
So the processor is certainly capable of doing 1080P.
Hmmmm, I wonder if I could swap in a different CMOS?
MUHAHAHA!
Crap, that didn't take long. I haven't had it much more than an hour and I'm already thinking about hacking it up......sheesh.

Ran some video in the dark last night.
In all fairness, it's always very dark here and not much ambient light, even in town.
Not much to see and my truck "booms" a lot on the audio (it's a rather "hot" diesel). For the most part, the video is dark except in the headlights. I'll try to get one of the videos up on youtube later.
Oddly, when I use media info to check the Fps it shows 24 Fps vice the 29.8 it did sitting on the table. Not sure what that's all about. Is it possible the processor is working harder at night?
Some of the button pushes are a little wonky. Like the "flip" option. For example: sometimes it works, sometimes it doesn't. Sometimes its press and hold the "REC" button, sometimes it's press and hold the "MIC" button.
The blue LED for "power" isn't on this one, it's amber. Much better for night use.
Hmmm, I'm beginning to think I should move all this info into it's own thread.....

Carrying on with my original plans, I took the camera apart again to measure the flexible flat cable. Since I plan to remote mount the CMOS sensor, I need an extended ribbon cable.
Luckily for me, the board and the sensor both use flip lock connectors. Pop 'em open and remove the cable. Installing and extension is just as easy as buying a longer cable.
The cable turns out to have 24 pins and is 14.45 mm wide. Works out to a pitch of .5
part numbers on it are 20624 80c 60v vw-1
Pretty common stuff.
Now to measure the truck between mirror and planned DVR installation spot int he overhead console. An 8" cable should do it. About the same length as the mobius guys are using.
ebay will provide a couple inexpensive cables to try out.

And that brings this up to date. More to follow as it develops.
