Can I use an old computer as a security monitor?
I am building a security system and I have an old Dell running windows 98 and with an Intel Pentium 3 processor and I was wondering if there was any way to configure it to send emails, text messages, etc. when the security system was tripped? The system will have an output port for each sector that will go high when there is an alarm in that sector. I was wondering if there was any way of writing some king of program to have the security system connected to the computer in such a way that each output on the security system would be connected to an input on the computer and when a specififc sector was tripped, it the computer would register that pin, and send a corresponding message for the sector? ( for example: the living room security output is connected to input one on the computer, the kitchen, input two, etc. when there is an alarm in the living room, input one goes high (or low, that could also be used) and the computer registers that input one has changed and sends a living room alarm message)? Thanks!
