You’re relocating to a place with security components
A new house may come with an installed home security system. All the alarms and cameras function well, are hung in the best areas, and are ready to go. In this instance, just turn on the phone to call and start a new monitoring contract. A Vivint installer will still show up to ensure there are no integration problems, and they might offer suggestions on where you should replace bad outdated components. It's a fast appointment, and you can get your alarm monitoring set up without having a bill for any new alarms and cameras -- unless you make additions.
The outgoing homeowners can transfer an existing Vivint contract to you for a small transfer cost to make the process simpler. If the owners are downsizing to a condo or smaller home, you keeping the home security service might be a condition of the sale.
You are looking to move and take your home security devices with you
You may want to take your favorite Vivint system with you to your new home when you move. Luckily, it's pretty easy to do, as many components are portable. You can uninstall each component by yourself or use a Vivint installer to take down everything. Then an expert will put in the same components -- and any smart devices you need to add -- in the new place. The home security contract will remain the same.
