I'm confused--you stated the horn is wireless, but once activated, a signal is sent via 12vdc to the horn? don't want to drill a hole through my wall.

Hello, that is a great question. The product is wireless, but please note there are two parts to it - the siren, and the siren controller, as shown in the images. This solution does not require added wires to work. The controller is battery powered and powers itself and the siren; it does not need a receptacle or plug-in power supply, nor does it require wiring back to a remote power supply. The controller is in an enclosure intended to go outdoors, so you can put both the controller and the siren on an exterior wall. But some customer elect to put the controller inside and run wires to the siren, and more often than not, this replacing an existing non-smart and wired security system siren, so the control might go at the old burglar alarm panel location, while the siren goes outside, at the other end of the existing wiring. Additional information and support can be found on our YoSmart website.

Will it work with google home ?

Yes, it supports Google Home. Thanks!

Does it support Apple OS?

But, of course! You do need one of our hubs, though: https://www.amazon.com/dp/B09FSS95G9?ref=myi_title_dp https://www.amazon.com/dp/B07TQLKQLJ?ref=myi_title_dp

Can you be anywhere in the world and trigger the alarm via the app?

Yes! As we like to say, Paris, Tennessee or Paris, France, as long as you've got an internet connection you can control it! Eric with YoSmart
