AVANTEK Wireless Doorbell, 1000 ft Range, 1 Button + 1 Receiver, CW-11

Hear the doorbell wherever you are. With a wireless range up to 1,000 ft (300 m) in open areas, the chime reaches upstairs, the basement, kitchen, garage, or backyard, and won't interfere with your neighbors' doorbells, so a guest at the door never goes unanswered

Choose from 52 melodies and 5 adjustable volume levels up to 115 dB, paired with a bright LED flash. The flashing light and loud chime make it helpful for the hard of hearing, the deaf, seniors, or noisy rooms where sound alone is easy to miss

Just plug the receiver into any outlet and mount the push button with the included screws, anchors, or adhesive tape, with no electrician and nothing to pair. Use it at the front or back door, apartment, office, store, classroom, or garage, or as a call button for an elderly parent or caregiver in another room

The transmitter is IP55 dust- and water-resistant and works from -4°F to 140°F, holding up to rain, heat, and cold by your door. Its lithium battery lasts up to 3 years, so it keeps working season after season

The Memory Function restores your last melody and volume after a power outage, with no resetting needed. There's no Wi-Fi or app to set up or manage, just a simple, reliable doorbell that's ready whenever someone is at your door
