Hello all. I am trying to build something like this for my father and he will not allow me to even purchase any parts until I can provide him with detailed plans and potential cost. I am not very tech oriented but can follow directions. I have an apple wifi system that connects to satellite internet. The location of the sensor/camera would be less than 50' with a thick interior wall as the only barrier. I have looked around the internet for something like this and have found various pieces of what I want but I do not know if I could successfully meld them together. The only thing that came close used a sim card and then I might as well get one of those home security monitoring systems. Thanks for any help!
