The new Nest Doorbell (2nd gen, wired) needs to be powered by wires delivering 16 - 24 V AC, and at least 10 VA (in North America) or 12 - 24 V AC and at least 8 VA (in Europe). While the Nest doorbell can replace most wired doorbells, there are some cases where the doorbell system, including doorbell wires, either doesn’t give enough power or gives too much power. In some homes, you may need to upgrade your transformer to meet the doorbell's higher power requirements. However, some doorbell systems are incompatible like a traditional doorbell system that uses very little power, so it’s important to make sure that the wires and transformer (power supply) meets the required amount of power so the doorbell can record videos.
Sorry, there was a problem. Please try again later.Regular phone inside wiring works fine. You don’t need Cat 5 or any special wire.
