AVANTEK DB-21 Waterproof Wireless Doorbell – 2 Transmitters, 1312ft Range, 52 Chimes, 115dB, IP55, 3-Year Battery

About This Product

If you need a doorbell that actually works everywhere – and we mean everywhere – this AVANTEK set is a beast.

It comes with two transmitters and one plug-in receiver, and the wireless range is a legit 1,300+ feet, so even if your workshop is out back or your front gate is way down the driveway, you'll hear it.
You can assign a different melody to each transmitter, so you know whether someone's at the front door, side gate, or back porch just by the sound.
There are 52 tunes to choose from, volume goes up to a loud 115dB (party-level loud) or down to silent with a visual LED flash if you don't want to wake the baby.

The transmitter is IP55 waterproof and works from -4°F to 140°F – rain, snow, or heat won't kill it.

Battery lasts up to 3 years on a CR2032.

Memory function saves your settings even after power outages.
Easy to mount with screws or adhesive pads.

Rock-solid and super flexible.
