Surely it's just a dash cam with a button and maybe some kind of comms module. There are many mass-market dashcams with a 'record' button that saves a time period before and after pressing the button, it's pretty standard usage. The only new thing is sending the video on, and making sure the time/location are correct (many cameras do this via GPS already - standard usage). I'm not seeing what is so expensive or unique.

Very profitable by the sounds of it!!!
