Meet the Modern Mini CB-11 Waterproof Doorbell from Avantek


Going wireless has become a perfectly convenient way to do a lot of things these days including adding a doorbell wherever it may be needed around your homes, offices, and workspaces. There are currently a number of wireless mini doorbells out there in the market and for a non-technical person, identifying and making the right choice amongst them might actually be a bit hard. So, we thought it necessary to review one of the coolest we have ever come across, named the Mini CB-11 Waterproof Doorbell Chime.

Made by Avantek, a US-based engineering company specializing in making advanced solutions for the home and business, the Mini CB-11 Waterproof Doorbell is a high-quality compact-sized digital doorbell system designed for full home coverage, with an extensive working distance that ensures you never miss any important guests or urgent deliveries, even if you are a few rooms away or on another floor.

Built with convenience in mind, the mini wireless doorbell comes in a wireless easy mounting design that ensures your interior decorations are not affected. The receiver is made compact enough so that it won’t block off any neighboring power sockets.

One of the best features of the Avantek digital doorbell is its innovative memory function. There are actually up to 52 tune melodies that you can choose from depending on your taste and preference. You can use the “Previous” and “Next” buttons located by the side of the device to go back and forth when going through the list. These chimes are amplified through a built-in 28 mm speaker that delivers rich and crisp sound, along with up to 5 adjustable volume levels with a maximum of 115 dB. Once the melody and volume are set, the device’s memory stores it and is able to recall it when required. So you don’t have to worry about setting the device all over again each time you put it on, even after a power outage. The memory will automatically take you to the last settings on the device. This makes it not only very convenient to use but also very friendly to operate.

The doorbell is also environmentally-friendly, having an IP55 dust-proof and water-resistant transmitter that is strong enough to work well in almost all outdoor environments. The transmitter will even work in the harshest weather conditions given its very wide -16°C to 60°C operating temperature range.

Working Range

The doorbell also boasts a 300m/1000ft ultra-long wireless working range and strong signal penetration that makes it almost impossible not to reach you wherever you are in your house. This range, however, depends on your operating environment as we are learned that metals affect the signal and shortens the transmission range, so you might want to keep it away from metals. The doorbell can be used in homes, factories, offices, classrooms, apartment blocks, villas, and large areas.
