It’s got an impressive range of up to 400m, 52 different chimes to choose from and five different volume levels, with the loudest measuring in at 115dB. The doorbell is IP55-rated, making it both dust and waterproof and Avantek says it will continue to operate in temperatures as low as -20°C. The Avantek Wireless Doorbell doesn’t do anything fancy or complicated but for the money, you will be getting a doorbell that’s perfectly serviceable and straightforward to install. This has a range of 128m and can be worn on a wrist strap or lanyard, and when you press the button it lights a green “I’m on my way” message to let your caller know you’re, well, on your way. The chime has a selection of melodies and the only thing to think about is the remote, which needs charging approximately every four days using the provided cable. If you’re not as fast on your feet as you used to be, this could be the doorbell for you.
