Ubiquiti unifi access hub - access control
Do I need this Door Acees Hub to open the door with the Doorbell G4 Pro PoE via finger scan or via app? If so, what are the advantages over the smaller version: https://www.galaxus.de/de/s4/product/ubiquiti-door-access-hub-smartphone-zutrittskontrolle-54394368 Ubiquiti Door Access Hub Mini Or do you ideally not need the DoorHub for the G4 ( https://www.galaxus.de/de/s4/product/ubiquiti-g4-doorbell-professional-bluetooth-kabelgebunden-klingel-tuersprechanlage-37343241 ) at all and the UCK-G2-SSD is sufficient: https://www.galaxus.de/de/s1/product/ubiquiti-uck-g2-ssd-netzwerk-videorecorder-nvr-netzwerkkamera-zubehoer-47744572? Thanks for your help
