Since I've started my new career which is truck driving, I've been thinking of making video along the way about the things that I see on the road especially when it comes to driving, maneuvering, parking (altho I ain't that good on it)...etc. just to give people a better understanding about the things we deal with on daily basis or at least educate them even a bit.

So, this is the setup I'm planning on doing:
I want to have about 3 camera system, 1 mounted on my dash serving as a dashcam, and the other 2 mounted on each rear view mirrors.

My budget can flexed to $800 but I hope I don't go that far.

Also, I do not own the truck so the ease of taking out the cameras and putting them back on should be something to keep in consideration.

My skills:
I'm kinda the average when it comes to recording and editing videos.

Since I haven't taken a final decision regarding this "idea" I'm open to all kinds of suggestions, even the crazy ones.

Thanks in advance for everyone in advance!
