REDLED RP-Orno Opera AC Wireless Plug-In Doorbell – 36 Melodies, IP44 Button, 100 m, Black

The REDLED RP-Orno "Opera" is a mains-powered wireless plug-in doorbell with a weather-resistant IP44 push-button, so the chime runs off the socket while the button survives outdoors by the door. No wiring between the two — the button talks to the chime over a 433.92 MHz radio link with up to 100 m of range.

The chime plays any of 36 melodies at up to 90 dB with adjustable volume (50–90 dB) and an optical flash, while drawing under 0.3 W from the mains. A learning system lets you add extra buttons — front door, back door, gate — to the same chime. The IP44 transmitter carries a name-plate window and runs on a single 12 V A23 cell; the black plastic housing suits a modern entrance.
