Nedis Wireless Doorbell — A Reliable and Flexible System

A doorbell should be reliable, easy to install, and weather-resistant. This wireless doorbell from Nedis meets all these requirements—and more. Utilizing wireless transmission at a 433 MHz frequency with a range of up to 150 meters in an open area, it ensures reliable communication even through multiple walls. The push button features an IP65 rating, making it resistant to rain, dust, and extreme temperatures ranging from -15°C to +50°C —perfect for outdoor use. The receiver plugs directly into a wall outlet (220-250 V AC), eliminating the need for battery changes and ensuring it is always ready for use.

A Flexible System with Intuitive Controls

This system is expandable, supporting multiple push buttons and receivers—an ideal solution for larger homes or properties. You can easily choose from 60 different melodies on the receiver—ranging from short tones to seasonal tunes—and adjust the volume across 5 levels, reaching a maximum of 80 dB, which is loud enough even for noisier environments. An LED ring on the push button provides visual confirmation that it has been pressed, while a multi-colored LED ring on the receiver allows you to select your preferred notification mode (sound, light, or both). ### Durable Design for Outdoor Use The button is crafted from high-quality ABS material, and with its compact dimensions of 66 × 36 mm, it fits perfectly on most door frames or posts. An IP65 rating ensures protection against water and dust—a crucial feature for outdoor installation. The button operates reliably even in challenging weather conditions, making it an excellent choice for homes, holiday cottages, and offices. ### Technical Data
