I was a indiegogo backer for this San Diego start up. Received my unit 2 months ago. No too shabby.

I encourage users to look into it. The unit connects directly into the vehicles OBD port.

It detects bumps and disturbances to a parked vehicle and sends an alert within seconds to your phone. Do any other car alarms do this?

Smart way to protect you car audio investment!
