## Network

Your network interface settings determine how the camera can communicate with the “outside” world and how the camera can be accessed from outside of the local network.

#### Internal Host Name

The host name is the unique camera name in the network under which it is accessible.

#### BOOTP/DHCP

BOOTP and DHCP are protocols with which IP addresses can be managed in a network and automatically assigned. The camera can use them to automatically obtain its network configuration.

Parameter | Explanation
--- | ---
Off | The camera’s network configuration is manually established. Enter the appropriate information in the IP address and subnet mask boxes and, if necessary, change the standard route or gateway and the DNS server. #### IP Address You can access the camera in the network via its IP address. Ask your network administrator which IP address is available. #### Subnet Mask A matching subnet mask needs to be entered for the IP address in order for computers to be able to communicate in a network. Again, it is your network administrator who will tell you which subnet mask to use. #### Default Gateway The gateway acts a relay between individual networks and it coordinates the data traffic between these networks. Enter the IP address of the gateway that should be used. #### DNS Server A Domain Name Service (DNS) resolves computer names to IP addresses. If you have a DNS on your network, you can specify up to three IP addresses of DNS servers. This is only necessary if you want to address computers using their name instead of their IP address for other configurations (FTP, email).
On client mode | Use BOOTP/DHCP to set the IP address and network configuration automatically. The gateways and the default route are automatically determined via BOOTP/DHCP and configured.
On server mode | This camera provides DHCP service to clients on the local network. The IP address of the camera will be 192.168.0.19 with subnet mask 255.255.255.0 by default. #### Default Gateway Enter the IP address of the gateway that should be used. #### DNS Server A Domain Name Service (DNS) resolves computer names to IP addresses. If you have a DNS on your network, you can specify up to three IP addresses of DNS servers. This is only necessary if you want to address computers using their name instead of their IP address for other configurations (FTP, email).

#### Additional IP Address

The camera can manage two different network configurations. If you enable this checkbox, the factory default IP address and the subnet mask will also be used, ensuring that the camera remains accessible at all times.
