Can one Eufy account monitor 6 basestation2/eufycams located at six different locations/networks

Hello, I have a client interested in monitoring his rental properties. He would like to put cameras at each location and view them all from one Eufy account. Is this possible or will each installation require its own on line account at eufy. Is there a limit for how many installations can be linked to one Eufy account?

He can help mtiple base stations and ceramic on one account, the limitation arises with how many cameras each base station can use as well as the fact that he would have to view each camera individually as there is no current way to monitor multiple camera feeds at one time
