Hi All,
So I have a old DSC alarm panel that came with the house - Installed by ADT.
Since I refuse to sponsor ADT with money I would like to try and get my Old(very old) raspberry to handle the simple task of emailing me the status.
now I know that the door and window sensors are simple open and close circuits and I can just hook them up straigt to the the GPIO on the PI and tell it to just check for open/close pins, but what about sensors such as the Motion Sensors which are 12V powered? I would most likely need to step this down with a optocoupler thus preventing the PI to buzzz out on me. as the optocoupler would separate the circuit from the Sensor to the RPI basically making the motion sensor act like a normal open and close circuit?
For now I do not need to control the panel just want notifications.
Then when done I can then perhaps use openvpn and dyndns and have the panel as a client connect to a VPN on my phone(for security reasons I would prefer VPN) dyndns is so that no matter how many times the ISP changes my cellphones IP address daily it will be reachable and I can then disable or arm the alarm?
Anyone every tried this with success?
