You moved into a home with a pre-existing home security system
Sometimes when you purchase a home, a security system is already installed. All the components function well, are hung in the best spaces, and are ready to go. In this case, you might see that you have to call and establish a new contract. A Vivint expert will still show up to make sure there are no integration problems, and they might offer options on an upgrade or two. It's a quick visit, and you can get your 24/7 monitoring set up without worrying about any new alarms and cameras -- unless you make additions.
The old homeowners can give an existing Vivint contract to you for a small transfer fee to make the transfer a snap. If the outgoing residents are downsizing to an apartment or retirement community, turning over the home security service might be a part of the sale.
You want to move and take your existing equipment with you
You might need to bring your old home security components with you to a new home when you move. It should be pretty simple to transfer, as many alarms and smart devices are portable. You can take down each alarm or camera by yourself or contact a Vivint installer to take down the system. Then an expert will hang the same features -- and any additions you want to have -- in your new place. And your home security contract will keep the same.
