Hello KNX professionals,Very big and nice forum you have here . I'm beginner with KNX, so I kindly ask you some advice/help.Is it possible to do the following schema and with which devices?: 1. I would like to put near door just switch (push button)2. Near that door will be hidden camera (IP with PoE or something similar)3. Now when visitor press the door switch, I would like to get picture on TV (PIP - picture in picture)Is it possible to do with KNX? I found "GIRA System 55 TV gateway" can this device be used to do this job? (camera picture will be not from the Gira door communication system, but from other camera)P.S. sorry that posting in english, but don't know german language, and google translator also not so good Thanks in advance,Zimas
