2N® Access Unit

Simple to install access control system

The 2N® Access Unit is a reliable access system using IP technology. With an eye-catching representative design, it is also sure to please with its simplicity, as it only consists of an autonomous IP RFID card reader, which also supports NFC technology, embedded with a controller in a single compact device. All you need to do is connect it to your own LAN network, and then configure it with ease via a web interface. The 2N® Access Unit offers a great price to performance ratio and is the ideal solution for small and medium firms.

Product highlights:

IP RFID and NFC reader, the 2N® Access Unit, combines all standardly used equipment - such as conventional readers, door controllers and IP converters into a single device. This makes both installation and operation of the access system as simple and low-cost as possible.

Customer references:

Intercoms and readers from 2N help us to satisfy the increasingly sophisticated demands of our customers. What’s more, their installation and setup is not complicated. We appreciate that all intercoms from 2N and the new 2N® Access Unit readers have the same settings and can be easily administered remotely.
