You cannot connect a second camera directly to the screen, as it is not possible to connect just one parent unit to two baby units. The connection works without Wi-Fi as the baby monitor uses a 2.4 GHz wireless connection. Interference can be caused by other devices, so it is advisable to move the devices to a different location or switch off interfering devices.

No. That's not possible, unfortunately. It would have been very practical for families with several young children...
