Last night I had a scary event, I looked outside and for a second I thought I'd left engine running and car in reverse and so as I went out to turn it off, I realised my car was being stolen.

What I want to do is set up an outdoor speaker positioned on my driveway so that next time someone triggers a movement sensor, it sets off a siren sound. Let's face it, I don't really want to meet any of these gits in future, detering them is far safer.
I have today installed a new Camera which has one objective and that is to trigger alerts accurately and without false alarms. It has no requirement of good facial recognition.
I am thinking about the following options and perhaps implementing two if reasonably manageable , but I would like any guidance to consider if they all would work, I am pretty sure C will work and have great sound:-
a) My cameras are all Dahua IP cams purchased through our IP man Andy. Next to the cameras RJ45 socket, there is a MIC socket, can I connect small speakers to this?
b) My POE switch is in the room next to the driveway, can I route a speaker off that using RJ45 and link it to my Blue Iris somehow?
c) I have a huge amp/AV receiver about 25 meters away elsewhere in the house used for my TV and Surround Sound, I can (memory pending) at night time leave the zone turned on which allows the AV receiver to view Blue Iris. Plus I would run a 25m speaker wire to the outside driveway area (which is well protected from weather) and it would on alert blast out a siren sound, directly onto the theives as soon as they step onto my land.
I know this would scare them off instantly as nobody really wants to get caught and this wouldn't give them time to act for any time unnoticed.
