I purchased the one for $73.00 discussed in this Link
. I believe there is even a short video clip.
I mount mine in the center of the dash, at dash level. The suction cup IS on the windshield
. It gives me a wide enough angle to pick up anyone cutting in front, etc. The quality is quite good. Putting the suction cup at the top of the windshield
would increase the focal distance and probably give a wider view at ground level.
I am satisfied with it. If you need more information, PM me, or we can start another thread.
Should I run into any law enforcement agency that says it is illegal on the windshield, I have a GPS disc, and I can move the GPS to the side window and move the camera back to the GPS disk. Hopefully if I run into that situation I'll just get a verbal warning - but!
