Hello. I recently installed four D1 Classic cameras at my house. I’ve noticed that when I turn off my mobile data, the cameras don’t record any events, and if something happens, I can’t see anything. I tested this by turning off mobile data and moving my car to a different location, and the app didn’t record or save anything. I understand that mobile data is unrelated to the Wi-Fi connection. Also, the aosubase unit only has 32GB of storage, and I’d like to expand it, but there’s no slot for an additional SD card. Any solutions to these issues? Thanks!

We currently offer three types of aosubase modules. You can distinguish them by checking the serial numbers on the bottom 
:
1. Models starting with H1L are the earliest generation of aosubase modules. Older versions lack an SD card slot and cannot expand memory capacity.
2. Models starting with H2L are the second generation of aosubase modules. You can find the SD card slot on the back to insert an SD card. Currently, the largest supported SD card capacity is 1TB.
3. Models starting with H2E are our lasted aosuCortex modules. They support SSDs and can be expanded up to 32TB.
We hope this information helps you better understand our Aosu products and better meet your actual usage needs. Thank you for choosing Aosu!
