If you choose to use a cash delivery service the only thing you will have to contend with is the physical security of the ATM. In most cases the ATM is installed in its own room. This would allow you to lock and alarm the ATM separate from your main security system. Some customers also add a camera to their security system that is inside the ATM room. Also the ATM itself has some alarm capabilities. The ATM comes with a harness that can be tied into a security panel and includes functionality such as: door triggers, vibration and heat sensors. Your ADT installer would be able to have the system go off if any of these triggers occur. A custom decal or sign could be added on or next to the ATM with that message.
