ᐅ IP doorbell system with RFID access / without video function

Hello,

as explained in this thread, I have the problem that I cannot use the Metzler doorbell system, which is already here. Therefore, I am looking for an alternative – maybe you have some ideas?

The following initial situation must be taken into account:

• Cable from the door opener to the technical room in the basement is available
• There is a LAN cable (PoE) from the outdoor unit to the technical room and a separate power supply
• No other cable runs from the outdoor unit to the technical room
• Control of the door opener must therefore somehow take place via the network
• Preparation for three indoor units (each with LAN/PoE and power supply) is available
• Three doorbell buttons would be good
• Door opening via RFID chip is desired
• We actually don’t need/want video

I would be very grateful for any suggestions of suitable doorbell systems! If you need more information, please feel free to ask.
