Paxton Access has introduced its Net2 nano, a wireless, single-door access control unit designed to extend the supplier's networked access control system. The unit removes the need for hardwiring between door controllers and a PC by replacing a wired connection with a wireless one. Simply connect a Net2Air USB bridge to the server PC and it will communicate with the access control units in range. The secure pairing procedure ensures that nobody else can connect to the control units.
