Welcome to the forum LaeinaJ.
12 hours of parking mode every day are doable i would think ( this kind of depend on the size and state of your car battery ) And also you then have to drive some too as it is after all a drain on your battery with a camera going.
Also since you are up North on the globe, you cant run your car battery too low on the voltage as that will give you starting problems in the winter, so keep up shut off voltage,,, over 12.2 is what i use, though i don't think that give me 12 hours on my old and small battery in my small car, but i don't want to / need to have parking guard for that long.
Since you are experiencing hit and runs, then you need a camera that have a pre-buffer so you get a little video leading up to the event itself.
Motion detect i can not recommend as it pretty much mean that if you don't park in a closed garage the camera will pretty much always be triggered to record by some movement within its field of view.
Another option are to do low bitrate but constant recording, this is the kind of parking guard i will go with when i get to try it out.
This mean there are room for much more as the files are smaller, and sound are recorded too, a thing you do not get if you use some kind of time lapse recording for parking guard.
Third is G-sensor activated parking guard, this i also like providing there are a buffer, and the G sensor are normally able to detect pretty small things, but someone keying your car might get away with it as a key along the paint are not really a major G ( shock ) event.
But someone denting your car by kicking it, crashing into it with a bicycle or motorcycle or car should be detected by a properly tuned G sensor.
And as you are touching upon yourself since it is hit and run thats your major problem, a dual camera will give you 2 X the chances of getting that capture you need.
Still up North as you are in Canada and i am in Denmark, then in winter time, little details like number plates can be a major issue for a dashcam, not least at higher speeds in relation to the camera.
But this is the same with all dashcams, not even sure you could get something really expensive in the professional segment that could do something in regard to that problem.
Have a look around in here, and dont be afraid to ask more questions, the dashcam market are a mess and there are many a things to consider in regard to ones need.
And we have no stupid question policy in here, cuz there are no stupid questions outside of asking the same one over and over and expect different answers to it.
