The Nedis WIFIDB11CWT wireless doorbell combines an indoor chime and smart siren in a device that plugs directly into a power outlet. It connects via 2.4 GHz Wi-Fi to the Nedis SmartLife app, providing audible alerts in your home and push notifications on your phone. It can be triggered by other Nedis SmartLife devices, such as door sensors, motion sensors and cameras, and can also be linked to automations, such as switching on lights.

The outdoor button is battery-powered and communicates wirelessly with the unit. The volume is adjustable, and a mute function is available for nighttime use.
