Hi Kenneth, welcome,

Please ask for support in the [dedicated Onvif app topic](https://community.homey.app/t/app-pro-support-for-onvif-compatible-cameras-release-2-0-41/28377), I’m sure it is solvable, when the TPlink cam supports the Onvif protocol ofc.

When that combo does not exist, just make a dumb battery powered siren smart with, say, a [Shelly UNI](https://kb.shelly.cloud/knowledge-base/shelly-uni). It’s a tiny WiFi relay and supported by Homey.
