WIRELESS WATERPROOF DOORBELL 300M IP44 110dB

Doorbell: no wires, no installation, no problems.

Do you like being tied to landline cables? No one does. Now you can get rid of your old doorbell once and for all. Old technology required chiseling into walls and drilling, wires, an electrician, and the doorbell could only hang in one place. But no more.

Order a doorbell now that truly solves problems and provides mobility.

This is a beautiful and sturdy doorbell for all types of doors, gates, and wickets.

Waterproof IP44 certificate

The doorbell is waterproof, resistant to rain and splashes for outdoor use. The new, tactile design and streamlined aesthetic structure make the doorbell prettier and more durable, with dust and shock resistance.

Plays how you want it: 36 melodies and 4 volume levels to choose from

The wireless doorbell is equipped with a high-quality, wireless stereo speaker, which provides clearer and more pleasant doorbell sounds and plays 36 high-definition music tracks. 4-level volume adjustment from 0 ~ 110dB. Loud enough to use the doorbell in the garden too.

Key features

  • It will work wherever there is a standard electrical outlet
  • You can attach it to any surface with strong double-sided tape
  • The receiver, which is the device with melodies, simply plugs into a standard outlet
  • Plays how you want it: you have 36 melodies and 4 volume levels to choose from (when a melody plays, you also see a blinking light - as in the picture)
  • Always works: indoors and in the yard, in frost and sun, and up to 300 meters
  • Installation. You already know that you can forget about cables, drilling, and wondering how to mount the button. Because you can literally stick it wherever you want.
  • Mobility. Does it need to ring in your son's room and in the living room? No problem. On the ground floor and upstairs? Fine. At home and in the gazebo? Absolutely. In the hallway and in a distant office? A piece of cake. At the reception and in the warehouse? Absolutely.
  • Ingenuity. If household members are away or don't hear the doorbell (or can't get to the door), connect a second doorbell in a neighbor's apartment or even in another house. Both will always ring.
  • Versatility. What if the delivery person had a doorbell button in their car, and when pressed, it would ring in the warehouse? Or what if customers no longer had to dial random numbers on the intercom, but could ring you directly?
  • Efficiency. 300 meters - that's the length of 3 football fields. And that's the range between the button and the doorbell. So you can actually connect a doorbell at your place and another on a different street - it will still work.
  • Durability. It's a beautiful, yet durable piece of electronics and plastic. It has an IP44 waterproof rating, meaning it can be safely used in the yard, and it operates in temperatures from -10 to 60 degrees.

The base plugs into the mains; it doesn't use batteries. There's one small battery in the doorbell.
