Here’s an in-depth review of ADT, covering its home security services, pricing, and overall value. Equipment costs typically range from a few hundred dollars to over $1,500, depending on the system and add-ons selected, with monthly monitoring generally starting around $25 to $40 per month.
Our Verdict: ADT is a strong choice for homeowners who want a professionally installed, full-service security system with 24/7 monitoring and smart home integration. However, it may not be the best fit for those seeking a fully-DIY system or greater contract flexibility.
Founded in 1874, ADT (American District Telegraph) has grown from a telegraph-based neighborhood alert system to one of the most recognized names in home security. With over 150 years in the industry, ADT is known for its reliable professional monitoring and commitment to customer safety. ADT offers nationwide service across the United States, with installation and support teams in most major metro areas.
The company provides a range of home and business security services, including burglary detection, surveillance cameras, smart home integration, and medical alert systems.

ADT’s long-standing reputation is backed by advanced technology, smart home compatibility, and comprehensive service offerings. The company has six nationwide monitoring centers that help ensure fast response times during emergencies. ADT also partners with Google Nest to offer modern, feature-rich equipment like doorbell and indoor/outdoor cameras. With a strong brand presence and reliable service, ADT is a trusted choice for families, seniors, and businesses alike.
ADT provides a full suite of home security services with both standard and premium options. Their offerings include:
ADT offers several security packages designed to scale with your needs, from basic entry protection to full smart home and environmental monitoring.
Many homeowners praise ADT for delivering reliable protection and peace of mind, especially with its 24/7 professional monitoring and smart home integration. These customers often highlight the reassurance that comes with ADT’s long-standing reputation and comprehensive security coverage. However, some reviews point to challenges with customer service, citing slow response times or difficulty resolving issues. Others note that the company’s long-term contracts can be restrictive and costly to break, making it important for potential customers to fully understand the terms before signing.
My experience with ADT has been excellent thus far. The system’s functionality and performance are top-notch. I appreciate the 24-hour technical support, which I find incredibly useful. Whenever I have any questions or need assistance, it’s reassuring to know I can quickly get in contact with a knowledgeable person. Overall, what stands out the most about ADT for me is its reliable customer support and seamless functionality, ensuring peace of mind in terms of security. – Consumer Affairs review
I got the service package for my family room and when we go outside in the patio, that’s taken care of. My wife said we don’t need it for the front door but I’m thinking about it. When I get ready to leave, such as when we’re going out the door in the laundry room, the system lets me know that the door is open. But I got the system cut off. I don’t put the system on until we go out-of-town. Having the system makes me feel more secure in my own home because you don’t know what’s going to happen. I like it good and I’m happy with ADT. The cameras were not in the package that I have but I would love to have one. – Consumer Affairs review
