Some wired door chimes in this selection offer an enhanced two-note melody for the front entrance.
Several wired pushbuttons are described as lighted or equipped with LED/white lighted center bars so the button is visible at night.
Smart wired video doorbells offer motion-activated alerts, cellphone notifications, cloud storage, and built-in two-way talk so you can receive alerts on your phone and converse through the doorbell.
