How can more than one camera run at the same time. (I have three cameras)

I have a Arlo 2 system. It recorded someone stealing something on my property. unfortunately another of the cameras was triggered at the same time so I didn't get that actual work being done on the removal.

The base station should be capable of sending 5 streams to the cloud simultaneously.

But if your base has a USB port, you could connect a thumb drive or USB disk to that port.  That should also back up recordings to the USB storage device.  That often will include recordings that somehow didn't make it to the cloud.
