This camera shines through a very consistent image quality. ME is interpolated the specified resolution. That is absolutely not helpful. One can hardly recognize important details (eg number plates) - ie as evidence unfit. Even the battery life is rather moderate; it is on longer journeys always forced wired (that's long enough) to load. The instrument is in my opinion almost outrageous - especially since the manual is clearly deviating from the real situation. That certainly would much better.
One must not forget the great price of course. But probably is not much more possible. I fall back here often to something. Nevertheless, the favorable price for an unsuitable device is still too expensive. If the manufacturer a device which fulfills its task not hinbekommt for the money, then you just have to raise the price higher.
Addendum (18/02/2014) Looking for a better camera, I found this much more expensive model, which is obviously is the same device as the discussed here.
