You’re relocating to a house with security alarms
A new house may come with an existing security system. All the components function well, are installed in the best spaces, and are ready to go. In this example, just pick up the phone to call and set up a new contract. A Vivint professional will still come out to ensure there are no usability issues, and they may offer options on where you should replace bad outdated components. It's a fast trip, and you can get your monitoring set up without having a bill for any new devices -- unless you make additions.
The old homeowners can give an existing Vivint contract to your family for a small transfer fee to make the process simpler. If the outgoing residents downsize to an apartment or retirement community, you keeping the security service may be a part of the sale.
You are looking to move and bring your old devices with you
You may want to bring your old Vivint system with you to a new place when you move. Luckily, it's fairly easy to accomplish, as most smart devices are plug and play. You can uninstall each component yourself or call a Vivint installer to dismantle everything. Then a pro will put in the same devices -- and any smart services you want to add -- in your new place. And your home security contract will remain the same.
