I recently built a new house out in the country.
One of the things I did was put in a directional driveway sensor. It is hardwired to the house that goes to a control box then a small siren.
What I would like to do is run a wire from the controlbox/siren to a devise that would be able to connect to a computer or something that could send my smartphone an email or alert. This would allow me then to log into my security camera dvr then to check out what is going on. I have no idea what something like this is called so its hard to search. Most of what I find is some type of cheep webcam that sends an email. I'm looking to use the components that I already have.
Thanks for your help.
