Wired or battery-powered — which is better?

Wired doorbells (like the Ring Wired and Reolink WiFi) give you continuous power, faster wake-up and, in some cases, 24/7 recording, but they require existing doorbell wiring and a compatible transformer. Battery models (Ring Battery, Blink, eufy E340, Tapo D210) are far easier to install but reviewers note slower live-view and the need to recharge every few months.
