Features

• Installation is incredibly simple – the wireless doorbell is ready to use right out of the box. Simply plug the doorbell receiver into an outlet, then use the included accessories (base plate, double-sided tape, and screws) to mount the doorbell transmitter wherever you want.
• Weatherproof Transmitter – The transmitter has an IP55 waterproof rating, making it suitable for outdoor use. The wireless range from the transmitter to the indoor receiver is up to 1000 feet (300 metres), utilizing advanced wireless transmission technology (FSK+FHSS) to avoid interference from other wireless devices and penetrate obstacles such as doors, walls, and floors.
• Smart and Compact Receiver – The doorbell receiver offers 35 selectable ringtones and 5 adjustable volume levels (including a silent mode). It can be expanded to support up to 32 transmitters and an unlimited number of receivers, providing comprehensive coverage for your home. You can set different ringtones for different transmitters to distinguish which doorbell has been triggered (for example, a "doorbell sound" for the front door and a "dog barking sound" for the backyard).
• Memory Function – The doorbell remembers your last settings (such as different ringtones for different transmitters) even after a power outage. No need to reset, making it very convenient to use and ideal for various settings such as houses, apartments, offices, classrooms, warehouses, and more.
