Thread: Open Door Lock

  1. #1

    Default Open Door Lock

    Does anyone knows how to open a door lock (with relais) by sending a 12V through the FXS port?
    Any ideas?

    Thank you in advance!

    The FXS port can't output 12v - i don't think it would ever happen

    A few years ago, I put together a VB program that monitored port 5060. I setup call routing to send calls there for a certain key combination. When the VB app detected packets, it would open a USB relay, which we had attached to a door strike relay. We still control access in our office with it today!

    Door strike:


    PM Me for VB app :-)

    Of course, now there are cleaner solutions, from vendors like mobotix and ABP...
