The fault here lies 100% with horribly designed IoT devices that turn into bricks when they lose internet connection.

Yeah the horribly designed alarm system that can't alert a central authority that something has gone wrong. Maybe we should just put huge air raid sirens on our homes instead?

In this case it would be a huge air siren on the list father's head when his tracker is blocked form the upstream.

What a wonderful idea!
