I have a customers that wants to have camera record via Motion Detection and record to a DVR. I can do this without any problem.

However they have asked that we add a horn or some external loud noice whenever the motion detection sensor is activated.

Has anyone ever had this request and if so what equipment did you use?

My 1st thought would be to use the X10 control portion of ZM and use either an X10 Buzzer, or control a X10 controlled outlet that a horn is plugged into.
Essentially you could control anything you want to have plugged in.

The how-to is in the manual.

I just posted something along these lines in and old "Feature Requests" thread. You might be interested.

I wonder if anyone is willing to try recompiling with this change so I can test out a better approach to audio alerts.
