Net2 is a networked access control system. A networked system gives the advantages of central control, event reporting and flexible control over users' access. Each control unit is part of a network but can run independently making its own decisions and remembering events.

The Net2 plus control unit connects to the central administration PC using an RJ45 plug into a standard TCP/IP Ethernet network. This greatly increases the flexibility of installation options on sites that have LAN/WAN networks. The Net2 plus control unit also has a RS485 connection. This means it can be connected to other Net2 plus or Net2 classic control units using a dedicated CAT5 cable.

One Net2 plus control unit can be the network interface to the LAN and also run a wired RS485 daisy chain of other Net2 plus or Net2 classic units, removing the need for an independent TCP/IP to RS485 converter.

Control units are sold as a PCB only, within a plastic housing or mounted within a 2A boxed metal/plastic mains monitored backup power supply.
