How to install Tuya IP PoE Video Intercom System with a Monitor?

The Tuya video intercom system includes a smart doorbell and a monitor. Since it features Power over Ethernet (PoE), the system can be easily installed by running the Ethernet cable (cat5e/cat6/cat6a) between the smart doorbell and the monitor. This article shows you how video intercom system can be installed through different wiring methods.

When buy the product, it should be noted that the video intercom system supports different PoE technologies we herein list them below:
Standard PoE: 802.3af standard, 48V voltage, endspan mode (1,2,3,6 for both data and power transmission)
Remark: the smart doorbell can connect to the standard PoE network switch, higher cost, standard PoE can better protect the smart doorbell. When using a PoE injector for connection, ensuing the injector is endspan (1,2,3,6) type.

Non-standard PoE: 12V or 15V voltage, midspan mode (1236 for data, 4578 for power transmission).
Remark: the smart doorbell can’t be powered through standard PoE switches, can be powered by 12V/15V PoE injectors or non-standard PoE switches (12V DC). Using wrong PoE switches or PoE injectors may damage the equipment.
