2 Video Doorbells

[ASPOONER]

What is the minimum transformer VA for 2 video doorbells? I currently have 2 of them hooked up to a 16v 10va transformer and everything is working fine, but am i killing the transformer lifespan by having it that way? Ive tried to search how many volt amps a video doorbell uses but i cant find any answers. I have a 30 va transformer but it seems like that is overkill? Any thoughts?

Since this is in the wireless doorbell section, I'm going to assume that's what you have. I wouldn't think that you're hurting the transformer since the current draw would be seemingly minimal and that if current draw increases it would only be to one device for a short time (both doorbells would likely never be used at the same time).

For a wired doorbell version, I think I'd use the higher capacity transformer.
