Plug the WiFi Chime in any room to hear your doorbell. You can adjust the volume, or turn on/off Chime whenever you choose. There is an optional light when doorbell rings for visual indication and you can pair up to 4 Chimes to your DoorCam. There is a choice of ringtones to suit you. Why not add another chime in the garden office or garage. Providing it will hook up to your WiFi, it will work. Quick, easy and very reliable. Mains powered (plug in) so no batteries to change ensuring it will always work.
