Monitoring Plans and Fees

Professional monitoring is a cornerstone of ADT's services, ensuring immediate response to any security breaches. Monitoring plans start at $29.99 per month for basic intrusion detection and can go up to $49.99 per month for more comprehensive coverage, including video surveillance and smart home integration. These plans offer peace of mind, knowing that trained professionals are vigilant 24/7, ready to dispatch emergency services if necessary.​

Installation and Activation Fees

ADT offers both professional installation and self-setup options. Professional installation fees start at $100, depending on the complexity of the system and any additional equipment. Opting for professional installation ensures that all components are correctly set up and functioning optimally, which can be particularly beneficial for larger homes or more intricate systems.

Contract and Warranty

When choosing ADT, it's important to be aware of the contractual obligations. A professionally installed system typically requires a three-year monitoring contract, which is standard in the industry. This contract ensures that you receive continuous monitoring services and support. Additionally, ADT provides warranties on their equipment, offering repairs or replacements as needed, which adds an extra layer of assurance to your investment.
