Wifi, POE, ethernet + PSU connectable Intercoms by Doorbird.

All models have external relays for controlling of electronic locks and strikes, garage doors, door openers etc. Plus relays for emergency exits buttons and internal chimes.

The BirdGuard is a fantastic model for external surveillance or secondary monitoring of other access controls, such as garage doors. Not sure if you closed the garage door, or wish a delivery to be placed inside? View your Birdguard the same as your Doorbird, but from inside your garage, and connect to your garage door motor to give access and monitor deliveries. The Birdguard also comes with an inbuilt siren and dog bark to scare off those unwanted guests, and allows for an even louder connection to an amplified speaker.

Made and designed in Germany. An intercom that goes straight to your phone or tablet, no more missing visitors or deliveries. 

Doorbird has an api available for integration into other services, and is Onvif compliant. 

Dont buy cheap imitations, buy the Intercom that works, connects quickly and allows other connections directly off the Intercom itself.
