 * QUESTION: Why do most victims have an alarm yet get no early warning of attack?
 * ANSWER: Because it's such a hassle to arm and bypass zones where the victims were cooking, entertaining, relaxing, or sleeping - besides, false alarms seemed such a drama...

What homeguard.co.za is trying to say is that the user interface of alarm panels as sold by http://www.inhep.co.za is a disaster. My solution is to use RS485 - ["RS485"] networks and configure the zones using a PC and embedded device connected to the serial port. All parameters are stored in a textfile and can have zones configured using a GUI PC interface if so desired.

With a PC anything can be done. Audio warnings with a human voice indicating that any sensor has been triggered would be trivial implement.
