But thing is, I think you want something that live uploads to the cloud.
what? no. you don't want this.
most of the footage is inherently useless and will never be viewed, so you'd be paying a recurring fee for bandwidth/storage for nothing. i don't even think such a thing exists on the consumer side.
99.999999% of dashcams on the market just write to a microsd card until they fill up and then start overwriting the oldest footage. in the event something bad happens, the footage is still sitting on there because it hasn't been overwritten yet. you pop the sdcard and grab whatever you need. some of them have smartphone apps that let you call up/record the footage straight from the app, but obviously, those cost a little more. they leverage wifi to do this, not a cellular plan.
justin - you probably want one of viofo's offerings. their product stack has cheaper offerings or expensive offerings depending on what you need. i suggest looking at vortex radar on youtube as he reviews them and has no problems calling them out when they do something stupid.
he also has a website
