How do I monitor a security system through the internet?
I am working on a basic security system based on discrete logic and was wondering if there was any way I could monitor the status of the system through the internet and possibly send messages to phones, computers, etc. through the internet when certain inputs went high, which would happen when the system was activated. For example, if a window was broken in the living room, is there a program or way to have my computer be connected to the system so that it would register that the input concerning the living room was at high (or activated) status, and send a text message or email to a phone or computer telling the recipient that a break-in had occurred in the living room? The basic way the system works is that the system will have outputs for each sector monitored, and, when the system is tripped in a sector, that sector's output goes high. I have heard about some microcontrollers marketed as "ethernet/internet appliances" from various places, and was wondering if I could use one of those? I also have an old iPAQ ( see my other pocket PC question for system specifications), and an old Dell computer with a Pentium 3 processor and Windows 98 that I have total free reign over, they are mine; is there any way I could use one of those? Thanks!
