The came that allow you to turn it to film either side, or for that matter backwards into the cabin of the car.
Well it is the same cameras you often see in Russian dashcam compilations, and who after a crash just film the sky, and if you see footage with the jello effect in it, it is also most often from a camera like that.
Also the cameras "dangling" off the windscreen like that are not that stealthy, but this don't matter to all people, and some even prefer to have their camera seen.
It is of course a 2 birds in one shot as with a camera you can turn you don't have to get a cabin camera if that is high on your wish list, personally i do fine with filming the person approaching me on my front or rear camera, and then just have the audio.
Though Danish police men are not as proficient in the law they are supposed to uphold as one would assume, then this don't bother me much at the moment, cuz i normally play nice with them as i am carrying a pocket knife ( and that's illegal here ) or some times even something substantial larger in a holster under my armpit ( still a knife )
So no need to make them too eager for something else but carrying on.
In my video busted again i am actually carrying a big ass Bowie knife, and when they find my baseball bat that had slid out from under the back seat i was expecting to get padded down.
But thankfully that did not happen,
In the video as the cop approach and probably triggered by me exiting my car, he "ready" his gun, really strange how trigger happy Danish cops have become, in 2007 driving my quad bike i met a really cool MC cop, he changed out of cop clothe and into a dirty overall, and then he drove around a little on another guys quadbike, while his gear and pistol and keys to his BMW cop bike was right there for anyone to grab.
But the main reason are of course all the cultural enrichment we have gotten from 3 world people most often Muslim in heritage.
Anyways back on the dashcams, the kind on a mount like that, well in most cases it is not from the major players, so quality and support might be a issue.
