The integrated motion sensor will trigger push notifications on your smartphone as soon as someone has entered your property. You can address the visitor via the built-in speaker and hear their response. The BirdGuard can be paired with the DoorBird Combi horn speaker/siren A001. This allows you to trigger a 100 dB siren sound and drive the visitor away. Or you can play a predefined sound, e.g. dog barking. This allows you to achieve burglary abort rates of over 90 %.
