Hi Carl,
Yes, the DS-KV6113-WPE1(C) can be used as a "Ring" doorbell to send notifications to the Hik-Connect app.
The key thing you need to be aware of is that the DS-KV6113-WPE1(C) cannot be directly plugged into the PoE ports on an NVR. If you want the doorbell notifications, it needs to be connected to the network separately (most likely using a PoE Injector) and then added to the app as a separate device.
