Vehicle security for long road trip

We did the two wheel chocks for rt-ft, lft-rear when parked overnight under a car cover. For restaurants, stores and overnight, we have a keyed under dash coil ground and hood lock. We also put in one of those radar sensor proximity alarms that is supposed to have a separate sensor for when someone gets close to the outside and another sensor for when someone reaches inside. The alarm is not reliable and feels like noise pollution anymore so it has dropped by the wayside. I tried unsuccessfully to find an auto alarm that notified my cell phone.

Enjoy the ride!!
How about one of those door bell cameras that send a vid to your phone.
