Both SimpliSafe and ADT are highly-rated and well-known home security companies. Though both provide comprehensive security options, there are a few differences between the two companies. Customers can install SimpliSafe themselves and browse pre-designed package prices online, while ADT offers professional installation and free in-home quotes.

What is the difference between SimpliSafe and ADT?

SimpliSafe offers a few more ready-made equipment packages than ADT, but ADT offers the option of integrated home automation. Both companies allow you to create custom systems. One of the biggest differentiators of note is SimpliSafe’s no-contract business model, which is atypical for the industry. In contrast, ADT’s average contract length is three years.
