This page describes the configuration of WiFi networking in DFN camera systems. DFNEXT type has WiFi interface installed, in the other systems it is optional. The default configuration is master mode, the camera system box acts as a WiFi access point (a network where a user in proximity of the deployed site can connect to the system wirelesly). The network name is the camera system hostname (eg DFNEXT007).

On some sites, or for testing before deployment, it might be useful to set the WiFi interface in camera system to client mode and connect to an existing WiFi network (WLAN). That allows Internet access to the camera system and remote access via LAN IP range and DFN VPN as well.

Both master and client configuration options are pre-set in /etc/network/interfaces, the one that is not currently active is commended out. The default (master mode) state is (here displayed only the USB WiFi sub-section of the /etc/network/interfaces file):
