AVANTEK CB-11 Wireless Door Bell - 1000 ft Range, 52 Melodies, 5 Volume Levels, IP55 Waterproof

Overview

Upgrade your home entry alerts with the AVANTEK CB-11 Wireless Door Bell. Designed for busy households, it combines a long range with crisp sound and simple setup, so you can answer visitors with confidence rather than frustration.

The system includes a plug-in receiver and a compact transmitter you mount on a wall. Setup is straightforward: attach the transmitter using the included screws and anchors, plus a small piece of double-sided tape if desired, then plug in the receiver. The result is a reliable notification that travels through walls and floors, without interrupting neighbors' devices.

Power, range, and performance

Expect dependable performance across a wide range of homes. The transmitter is powered by a long-life lithium battery, designed for years of use, while the receiver sits in a standard outlet for instant access. The doorbell can operate in harsh conditions: it carries an IP55 dustproof and waterproof rating and works in temperatures from -4 °F to 140 °F. The system supports a generous wireless range of up to 1000 feet, so you won’t miss a visitor even when you’re in another room or on another floor.

Sound matters for doorbells, and the CB-11 delivers. A 1.1 inch stereo speaker fills your space with clear, balanced tones. You can choose from 52 melodies and adjust the volume across five levels, with a loudest setting of up to 115 dB, letting you tailor the alert to your space, whether you’re indoors, outdoors, or wearing hearing aids.

Memory, reliability, and everyday practicality

The transmitter remembers your last melody and volume level after power outages, so you don’t have to reset it repeatedly. This thoughtful memory function makes daily use smoother and keeps your preferred alert in place after a brief interruption. The system is designed with low power consumption in mind, helping the battery last longer between charges or replacements.

Real-world use cases

In a multi-room home, the CB-11 keeps you connected across the entryway, kitchen, and living areas. In apartments or shared walls, the interference-free design helps you receive notifications without cross-talk. For homes with children, elderly residents, or outdoor activities, the LED flash option adds a visible cue to accompany the audible chime, ensuring alerts aren’t missed in noisy environments.
