INTERNET FIREWALL
Effective protection for your building network
A1051
GREATER SECURITY
IN YOUR NETWORK
The DoorBird A1051 Internet Firewall effectively protects your internal door
communication network from unauthorized access from inside and outside.
The product can be easily installed on site between the internet router and the
network cabling for your DoorBird door communication system. It is preconfigured
and instantly ready for use (plug & play). The Internet Firewall filters trac and
only allows DoorBird door communication products to connect to the network.
Attackers attempting to use the network connection of the door station or the
indoor stations are securely blocked from gaining access to the internet.
DOORBIRD A1051 INTERNET FIREWALL
SECURITY IN LARGE APARTMENTS AND OFFICE BUILDINGS
The DoorBird A1051 Internet Firewall protects your building network from being
misused, from inside and out. Main entrances, side entrances, underground parking
garage driveways, access to building floors, and indoor stations are thus protected
against unauthorized access to the internet. Attackers attempting to manipulate
the door station or indoor stations are securely blocked from gaining access to the
internet or the internal building network. The Internet Firewall is automatically
updated in the background (“over the air” or OTA) to new network conditions of
the DoorBird cloud servers.. The DoorBird A1051 Internet Firewall reliably blocks
unauthorized network trac, keeps disruptions from happening, and ensures the
network runs smoothly in your buildings.
SECURITY IN SMALL HOME NETWORKS
The DoorBird A1051 Internet Firewall protects your home network from being
misused at door stations installed outside at the main entrance or the gate.
Attackers attempting to manipulate the door station or indoor stations are securely
blocked from gaining access to the internet or the internal home network. The
Internet Firewall is automatically updated in the background (“over the air” or OTA)
to new network conditions of the DoorBird Cloud servers. The DoorBird A1051
Internet Firewall reliably blocks unauthorized network trac, keeps disruptions from
happening, and ensures the network runs smoothly in your home.
