Yes, the MT10, MT12 and MT20 sensors are now available. You will need at least one WiFi6 AP or 2nd-generation MV camera (MVx2) in order to act as a BLE gateway for your sensor(s).
They are SO easy to setup, it's ridiculous..! 😁
I'm not sure about initial stock levels (they are proving popular) but contact your Cisco Reseller for the latest.
