From a professional monitoring standpoint, Vivint costs $1 more than ADT. Vivint home monitoring starts at $29.99 per month, while ADT starts at $28.99 per month.
However, the total cost of your home security system will depend on the number of products (such as sensors and cameras) you choose.
Both companies offer system packages (ADT’s basic package starts at $479.20 and Vivint’s basic package starts at $599.99) and the ability to tailor a package to meet your home’s security needs.
