For optimal performance of the V2 video doorbell, a transformer with 12–24 volts AC is required.
This voltage range ensures stable operation and consistently provides enough power for video functions, motion sensors, and other smart features.
Make sure your transformer falls within this range to avoid issues such as:
Power loss
Delayed responses
Connection problems
If you’re unsure whether your current transformer meets these requirements, consult a certified electrician or check your system’s specifications.
