I am trying to find (and can't at the mo') a siren, or any loud sounding item that will activate when I turn on at the mains socket. I have googled quite a bit for one.... wondering if such a thing exists. any ideas guys.
What I want is a siren that can be plugged into a smartplug. If and when my Blink xt2 camera system picks up intruders in the back garden while away on holidays I can activate for as long as I want to scare them away. No good just watching them on my smartphone while they break into my house / garage.
