You're asking the wrong question.

Sleeping the CPU until you get an interrupt from an IMU or simple motion detector is a common way to do this. It's not about being stealthy so much as extending battery life.

If you're going to try and track this stuff for real, keep in mind most devices like this use motion sensors to go into low-power mode when stationary and only transmit on the move.

Sometimes the smart think is to encourage folks to do their thing, and if it's successful buy it back in-house.

They’re going down whether you stay or not. Take care of yourself, nobody else will.
