Personally, I chose ADT to secure my home and the experience has been impressive. Their systems not only provide intrusion protection, but also monitor various aspects of the home such as smoke, gas leaks, and temperature. ADT's impressive experience and trusted reputation made it an easy choice. Their contacts for more information can be found at: ADT Customer Service https://adt.pissedconsumer.com/customer-service.html Contact with their customer service team went smoothly. They provided the information and support needed to install the system. When choosing a home security system, it is important to consider the needs of your home and personal preferences.
