Questions about Recording a Live streaming

General
1

1- Is there any tool to record all AOSU cameras in in one device at home? The SD card is not reliable. Also if someone steals the camera, takes all the recordings as well.

2- Is it possible to increase live streaming capacity of the AOSU app to more than four cameras? At the moment it can only live stream 4 cameras.

The only other option I know of is Cloud Storage in case someone steals your camera.

Except for the doorbell, the four-camera D1 Classic records are internal to the interior HomeCortex SD card, not in the external cameras. At least, the footage is saved from the thieves, though not the camera.
