AVIOSYS makes a IP sensor range of modules, i have the WEB-9201 IP Sensor, it has 4 inputs only, althogh the main board i have has the conectors for the POWER output board as well.
I put this in the programing section as all I really need to do to hook it up to my alarm system is just a few wires.
I am looking at writing a small java app that will popup a window when a sensor changes state.
I may also write a web app to do a better job at displaying the sensor readings, the built in one is crap.
The manual is also crap, written in chinglish (chinese translated to english). there are jumpers and connectors on the board that are not mentioned anywhere in the manual.
It also come with a metre long 15 D-Sub cable and i only need 20-30mm, so i'm going to have to work out the pins (i hope stright though) to make a short cable.
