AVANTEK Wireless Doorbell CB-11 – 1000 ft Range, 1 Button + 1 Plug-In Receiver, 115 dB Volume, LED Flash, 52 Chimes, Waterproof, 3-Year Battery

A doorbell you can't hear from the backyard or the basement isn't really doing its job, and a lot of "long range" wireless doorbells fall well short of their advertised distance once walls and metal get involved. AVANTEK's CB-11 is rated for up to 1000 ft in open air, which in a typical house translates to reliable coverage through multiple floors and rooms — the plug-in receiver delivers up to 115 dB across 52 melodies, and a bright LED flash fires alongside the chime, which matters if you or someone in the house is hard of hearing or the TV tends to drown out sound alone.

Setup is genuinely just plug-and-mount: no app, no Wi-Fi, no electrician, just the included screws or adhesive tape for the button and an outlet for the receiver. The transmitter is IP55-rated for rain, heat, and cold down to -4°F, and the lithium battery is rated for up to 3 years before you'll need to think about it again. A memory function restores your last melody and volume automatically after a power outage, so it's ready the next time someone's at the door — a straightforward, no-subscription option if you just want a doorbell that reliably works, not another smart-home app to manage.
