The 2N® Indoor Talk response unit design is perfect for any department or home. The aesthetic appearance of this product was achieved using a glass surface and a very striking backlight of its icons. However, we particularly emphasized the selection of the highest quality audio components in order to achieve excellent sound. You can talk to visitors outside and listen to them as if they were right next to you. Made with glass and other high quality materials, its slim body barely protrudes from the 10 mm wall. Power supply 12VDC +/- 10% adapter or 802.3af PoE. LAN interface 10/100BaseT, RJ-45. Dimensions: 185 x 128 x 48.2 mm.
