    But you will be able to hear the screams from inside.

    PIR sensor systems have been in use for this long before the IoT nonsense took hold. There are probably a few still being sold (primarily as shop presence sensors, as you described).

    We have an infra red beam across the drive which when broken triggers an audible alarm in the house and workshop. At night it also triggers 4 separate lights that come on for 10 minutes. OH made it from parts from Maplin or Radio spares and uses a bog standard red reflector to reflect it back to the sensor. It is very useful especially as it alerted me to a couple of men who were apparently casing next door's storage area, they got photographed by me as they drove out.

    I bought a PIR detector on Ebay.
    I have the receiver in my cargo pocket.

    For some reason, even with a notice, delivery drivers insist on walking up the path and tapping on the door.

    So I open the door, ignore the proffered parcel, say "Bell not working?", ring bell, look perplexed, take parcel, say thank you and smile all friendly like.

    Waterboarding at Guantanamo Bay sounded like a radical holiday opportunity until I looked it up.

    We have the same problem. What is it about delivery drivers and bells?
