Which base station / hub to purchase

[nivaar]

I have an AVD2001B wireless doorbell/camera, which I'd like to be able to view as a camera in HomeKit. Looking on the Arlo website, amazon etc, it seems like there are two or three different hubs which could do this. The differences between them seem non-existent: which one should I buy to make this connection to HomeKit work?

Best to get a smarthub (VMB4540 or VMB5000). The VMB4540 is single band (2.4 ghz wifi only), and lets you add a USB drive (for example a thumb drive) for local storage if you want that. The VMB5000 is dual band (2.4 ghz+5ghz wifi), and lets you add a microSD card for local storage. The doorbell only has 2.4 ghz, so the less expensive VMB4540 is fine.
