You’re moving into a place with security devices
A new house may come with an installed security system. All the alarms and cameras function well, are installed in the right areas, and are ready to go. In this case, just get the phone to call and establish a new monitoring contract. A Vivint expert will still come to your home to make sure there are no integration problems, and they could offer options on where you should replace bad outdated components. It's a fast appointment, and you can get your monitoring set up without having a bill for any new alarms and cameras -- unless you add on.
The old homeowners can move an existing Vivint contract to you for a one-time transfer fee to make the process simpler. If the owners are moving to a condo or retirement community, turning over the security contract may be an addendum of the sale.
You are looking to move and take your home security components with you
You may want to bring your favorite smart devices with you to a new place when you move. Luckily, it's pretty simple to accomplish, as many smart devices are portable. You can uninstall each component by yourself or contact a professional expert to take down everything. Then an expert will hang the same components -- and any smart items you need to add -- in the new home. Your home security contract will keep the same.
