Since we're just talking telemetry, wouldn't it be more like the delivery guy turning up and taking note of all the contents in your house - including make and model numbers where available - their exact position in each room, which container(s) they're in, the size and position of the nearest windows, and also the make & model number of the alarm system you have.

All "to provide you the best delivery service possible".

Yeah, right. That's completely above board. Suuuuuuure.

That depends on your delivery service. There are some that do what you describe, analog.

However, not all telemetry is like that, some telemetry does not inspect the inside of your house at all.
