You have to also install a new sync module. You will then have two complete systems in two different locations running under one mobile app. Different location = a 2nd place far far away aka not a 2nd camera in the same home.
The sync module is the hub of the system. It can’t talk via wifi to cameras that are in a different location. That sync module, cameras, and wifi router ALL have to be in 40-80 feet of each other. 40-80 feet is a good starting point max distance for reliable/consistent wifi signal.
Add a new system is the choice to do the 2nd location on the mobile app.
