SimpliSafe vs. ADT Overview

SimpliSafe Overview

Here are a few SimpliSafe benefits:

  • Clear and inexpensive pricing
  • Portable equipment
  • No long-term contract required for professional monitoring services

SimpliSafe is a relative newcomer to the home security industry, and it offers a different paradigm from traditional companies like ADT. The founders of SimpliSafe couldn’t find a good security solution for renters, so they pioneered their own wireless hardware that’s easy to install and remove.

ADT Overview

Here are some top selling points of ADT:

  • Longevity and a good reputation in the industry
  • ADT has the largest nationwide network of monitoring centers
  • Six-month money-back guarantee on installation and monitoring fees*

ADT Home Security is one of the most experienced and best home security companies in the industry. Originally founded as a telegraph company, the business expanded into security alarms in the early decades of the 20th century, and it now serves over six million homes throughout the United States.

Our Conclusion

ADT and SimpliSafe are both excellent choices for home security. SimpliSafe may be best for people who want a DIY, portable security system, those who are on a budget, or renters, considering the company has a la carte options and requires long-term contract.

Alternatively, ADT is probably the best choice for homeowners who want a traditional, professionally monitored home security system and have a little extra room in their budget. ADT’s monitoring prices tend to be on the high side, but you’ll get an established name with a nationwide resource network.
