Gdetrailer - I really appreciate the technical analysis but I'm really not here for that. Clearly, the techniques that you've outlined don't deliver the results - you're right. But there is another way. Please don't be angry, I don't mean to offend.
Wa8yxm - Yes, it functions very similar to that. I've chose a burst of still photos rather than real video to save data. The monthly plan cost is very data dependent. The system will pause and then burst again until the motion detect is null. The system consumes much more power during an active alarm.
Incidentally, the design group that I manage in my real-life (paying) career designed the ODB-II tracking module that you mentioned. Not specifically the one for Verizon but one used for insurance companies and car rental companies.
What I really need to know is if anyone would buy it? So far it is a zero.
