Unable to sync additional arlo cameras

[arlo-123]

A friend of mine gave me their unused, completely new 2 Arlo cameras with the NETGEAR base package. It is not refundable but anyways, now I have it. I already have a NETGEAR base with 2 Arlo cameras so I tried to add on the 2 new Arlo cameras (from my friend). Although, it is not working. I tried following the instructions: press the sync on NETGEAR for 2 seconds, then 2 seconds on one of the camera, the camera blinked blue for 10 seconds, then rapidly flashed. In the instructions it says this means they have synced by after looking at my phone Arlo app, it does not show up. I tried this for both of them and even switched out the batteries but no luck.

If there is no solution to this, could I run 2 NETGEAR bases using on Arlo account?

First don't press the sync button for two seconds... use more of a quick press and the na sec later press the camera button.

Make sure your phone is on the same network as the base duirng setup...

And, there is no limit to the number of bases on any account
