if you go thru amazon the order might get delayed as they prioritize other things first.
But most / many of the sellers also have their own stores, where you might even save the amazon fee.
Most cameras are for filming strait forward and strait out the back, and many do not allow you to turn the camera towards a door window for instance, but they will record good audio at least
The ones that do allow you to turn the cameras are often on less ideal mounts, that in some cases can be a problem, and if not that then they hang off the windscreen in order to be able to be turned so they are not stealthy.
Here in Denmark it is recommend to film engagements with the police on your phone, which the police can do nothing about at least as long as you are not in handcuffs.
My phone are installed off the driver side door and a fixed piece of glass on it, so in the pout it is right in the face of a cop, and quite fast to get a recording going.
Danish police are going bad too, but the biggest problem is we only have about 50% of the cops we would need just to break even with crime, its so bad here now criminals taunt police as they know there is little they can do due to manpower issues and also a avalanche of rules, a cop here pulling his gun will give all kinds of problems, to a degree they dont pull them now even when they really should have, like threats against some politicians or other public figures just using their constitutional rights.
