New installation question

I am considering installing a few ST Things such as Open/Close and motion sensors. What is the recommendation with regards to discontinuing the existing home security system (e.g. ADT).


Please click on the magnifying glass and type “ADT”, there are tons of info there and some of which are active. As such I trust security as of now to professionals. And now let’s go and Piggy back in of those active threads, buddy or make it active! :wink:
