Net2 is a network access control system. A networked system offers the advantages of central control, event reporting and flexible control over user access. Each control unit is part of a network, but it can function independently by making its own decisions and remembering events.

The Net2 plus control unit connects to the central administration PC using an RJ45 plug on 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 an RS485 connection. This means that it can be connected to other Net2 plus or Net2 classic control units using a dedicated CAT5 cable.

A Net2 plus control unit can be the network interface to the LAN and also run a wired RS485 chain from other Net2 plus or Net2 classic units, eliminating the need for an independent TCP / IP to RS485 converter. Net2 plus is also available with a Power over Ethernet power supply (PoE). PoE is a technology that allows the transmission of power and data through Ethernet cabling. Net2 plus with PoE simply connects directly to the existing LAN using a standard RJ45 plug (as long as it is powered by a compatible PoE switch or a PoE injector).

Control units are sold only as a PCB, inside a plastic housing or mounted inside a backup power supply monitored by a 2A metal / plastic case. The Net2 plus unit now comes with a PoE + power supply in a metal / plastic enclosure; no separate backup power supply is required.
