Samantha
Ocean Springs, MO
I’m so thankful we had ADT protection and that I got that phone call from the ADT representative. It saved my house. It saved my family. It saved my dog.
Katie
Fresno, CA
I knew if I hit the red button, someone would come on the line. All I remember shouting was ‘Emergency 911.’ The ADT dispatcher took it from there. I thank ADT for that call that was made for me and truly believe it saved my life.
Wendy
Seattle, WA
ADT gives me peace of mind. It makes me feel more comfortable knowing that my son is protected also. I’m so thankful they called so fast and that police officers were here so quickly to help us.
