About – Net2 is a networked access control system. A networked system gives the advantages of central control, event reporting and flexible control over users’ access. The Net2 nano control unit connects to the central administration PC using Paxton’s proprietary and secure wireless technology. Net2 nano control units can be mixed with Net2 classic and Net2 plus control units and can be added to existing Net2 installations. This will be particularly useful where wiring would prove difficult. Control units are sold as a PCB only, within a plastic housing or mounted within a 2A plastic boxed backup power supply. The Net2 nano cannot be mounted in a metal box because of its use of wireless technology.
