Both companies provide multiple services that can be used for commercial or residential purposes but for the sake of this comparison, both companies will be compared on residential services only.

ADT Security

By now, almost everyone knows who ADT is and has at least a basic idea of the services this home security provider offers. It operates on a national network.

ADT Regular Services:

  • 24-hour monitoring
  • Hardwired or wireless systems
  • Door/window sensors
  • Keypads
  • Motion detectors

  • Control panel

ADT Customizable Offerings:

  • Celluar backup
  • Critical conditions

CPI Security

The name CPI security isn’t as recognized as ADT, mainly due to its limited operating area. CPI operates mostly in South Carolina, North Carolina, and Georgia.

CPI Regular Services:

  • 24-hour monitoring
  • A keypad
  • A pet-friendly motion detector
  • Two door sensors
  • A communication system that works one way

Customer Service and Other Details

Consumers like options, guarantees, and good customer service. In these areas, ADT and CPI can vary greatly.


In this category, ADT is more customer-centric than CPI, providing a money-back guarantee for the service (up to six months after installation) and insurance coverage with a deductible of up to $500 for any personal property that is removed from the home before emergency responders arrive.

CPI provides a False Alarm Guarantee that may include compensation for fines charged by law enforcement in the event of an unnecessary call to police.

Installation and Relocation Fees

ADT provides free installation for relocation if an account has been open for two years prior to the move. The free installation is for a relocation within the continental United States.

CPI does not provide a free installation for relocation or home renovations that require moving or altering the existing system.


Both companies require a contract but ADT only requires 36 months, while CPI requires up to 49 months.

Customer Reviews

While any company can get a few negative reviews here and there, common complaints are usually a good indicator of customer service practices.

ADT has an A+ rating with the BBB and a long list of verified testimonials that praise different aspects of the security service and customer service for this company.

CPI also has an A+ rating with the BBB but has been found to have some very negative reviews that it has to overcome.

One such review stated: “TERRIBLE CUSTOMER SERVICE. My family relocated out of the area and the company is mandating that we pay for the ADDITIONAL 31 months of the contract. Due to the poor customer reviews, the new homeowner declined using CPI. Now we have to foot the bill. BEWARE! They are more concerned about getting your money and locking in a contract as opposed to actually providing decent service. I expect this company will just go downhill from here… They could care less about how they are perceived.” – Janna W., Yelp 7/30/2014
