Before You Start
Make sure all devices are installed and powered on properly, and on the same local network(LAN).
Set the Door Phones in Public Areas
The building number of door phone A will be 0 by default, installed at the community entrance, which does not require extra configuration for basic calling, unlocking, and monitoring.
If the community only has one building, the building number of door phone B will be 1 by default. You do not need to change this setting.
If there are multiple buildings, you need to set up the building numbers on the device’s screen or its web interface,

Set Indoor Monitors and Door Phones in Apartments
The indoor monitor and door phone installed in each apartment need to be paired up in the solution.
Select the device language and time zone on the device's initial setup screen.
Tap Next. For the C313W-2, you need to choose the device working mode. Set it to Slave Mode since NS-2 works in Master Mode. If it is not a 2-wire device, simply skip this step.

Set the device location and set its device role. If only one indoor monitor is installed in an apartment, designate it as the Master. In this case, it will be the main device where users scan the QR code and register the SmartPlus account. When the device is in Slave mode, select the device number ranging from 1 to 8.

Tap Next to set up the network.

Tap Next. The indoor monitor will scan the devices on the same LAN as it.

Check the door phone and tap Confirm.

When pairing succeeds, “family sent successfully” will display on the device screen.
