The power supply set is intended for installation in new and existing houses (apartments). It is used in places where it is possible to bring a LAN cable into the installation box, or where this cable is already fed, however, there is no power supply in the installation box. The set contains an adapter (which you plug into a socket) and a PoE injector, which you connect (with a LAN cable) to LARA. The PoE injector is adapted for mounting in an installation box. This is a LARA wire connection.
