Installation options and cost

A significant difference between a SimpliSafe home security system vs ADT is the installation process. Almost all ADT systems require professional installation, and installation costs depend on the system you choose and the size/layout of your home. ADT Blue does offer DIY options, but is best suited for renters.

SimpliSafe, on the other hand, is first and foremost a DIY home security solution. All products are DIY-friendly so that you can install them yourself at no cost. Should you want your SimpliSafe system professionally installed, you can purchase installation at a fee.

Monitoring options

Both ADT and SimpliSafe provide professional monitoring plans, but their options are very different. You can use SimpliSafe products without monitoring, although you’ll miss out on certain features. ADT products can also be used without monitoring, as long as your system is not locked into a contract.

ADT Monthly Monitoring

ADT monthly monitoring plans are determined by the security equipment used. This service includes 24/7 monitoring by 9 centers, intrusion detection, voice control ability, and fire, carbon monoxide, and flood monitoring. When applicable, it also provides video surveillance and home automation services. ADT’s monthly monitoring is typically tied to a 36-month contract.

SimpliSafe Monthly Monitoring

plans are the same for all systems and are not tied to a contract so that you can cancel at any time. SimpliSafe’s professional monitoring includes video recording, alarm and secret alerts, notifications, and 24/7 monitoring and emergency response by six centers. SimpliSafe also offers self-monitoring that includes camera recordings.

Customer support

When you use ADT’s monthly monitoring plan, you also have access to 24/7 customer support. ADT also offers an online Help Center that potential and current customers can use to learn more about ADT systems, access account information, or chat with a customer support team member. 

SimpliSafe has a customer support line open every day from 8:00 AM to Midnight (ET). They also have an online Help Center that customers can use to find more information about their products or chat with a customer support team member between 9:00 AM and 5:00 PM (ET). 

Overall, SimpliSafe ranks higher when comparing ADT vs SimpliSafe customer support.

Positive SimpliSafe reviews mention knowledgeable and professional customer service team members, although some mention issues regarding fixing damaged products.

Ratings and reviews

The comparison between a SimpliSafe home security system vs ADT home security system shows each company provides solutions to home security but offers different products, features, pricing, and plans. ADT is a professionally-installed home security system starting at over $500, whereas SimpliSafe is a DIY home security system with their most expensive package costing just over $500.

Our recommendation: ADT or SimpliSafe?

While both ADT and SimpliSafe offer great options for families looking to protect their home, we can’t recommend either brand to everyone.

ADT will be the better choice if you are looking for a professionally installed and monitored system backed by over 140 years of experience. It is also the better option for robust security features and smart home functionality.

SimpliSafe is the better option if you are looking for a flexible DIY solution with plenty of options for system customization, monitoring plans, and installation options. It’s also a better choice if excellent customer service is essential for you or if you have a tighter budget.
