ADT and Deep Sentinel home security systems are considered to be some of the more expensive and more thorough systems on the market. While they are both professionally monitored systems, they are dramatically different in how they keep your home and family secure. While ADT relies on multiple devices and a professionally installed/monitored system, Deep Sentinel uses continually monitored outdoor security cameras and predictive Artificial Intelligence to prevent intruders from gaining access to your property at all.

ADT and Deep Sentinel home security systems use state of the art technology to monitor and secure your property 24-hours a day. ADT uses a variety of devices to secure your home inside and out, providing full home automation as well as two-way communication between you and whoever may be at your home. Deep Sentinel uses outdoor surveillance cameras equipped with two-way communication to identify and communicate with anyone who visits your property. With their predictive software constant human monitoring of their system, they can identify potential threats before they become a problem.

Differences: Deep Sentinel vs ADT

There are no devices to be triggered, just constant video surveillance of the property and communication with anyone who attempts to make an entrance.
