BITIWEND Door Chime🔔 【58 Melodies & 5 Volume】

The wireless door chime from BITIWEND features 58 chimes and 5 adjustable volume levels (0 dB to 110 dB) to meet your needs for different occasions. It remembers your last melody and volume level even after a power outage, so you don't need to reset your previous settings.

👍 【Door Entry Window Open Alarm】

The BITIWEND door chime can be used as an alarm to remind businesses when the front door is opened, helping to deter break-ins. It's perfect for families with children or elders.

🌐【Up to 600 FT Working Rang】

The wireless door sensor chime has a working range of up to 600ft in open areas, allowing you to cover your house or store to ensure you never miss a visitor. Note that the battery level will affect the signal receiving range, so it's recommended to change the batteries once every 12 months.

🔔【Expandable】

Each door sensor or receiver can be expanded, allowing you to use them with additional BITIWEND door sensors or doorbells. You can install them in your dining room, bedroom, living room, garage, yard, or your store and office.

🔧【Easy to Install to Use】

To install, simply plug the doorbell receiver into any standard outlet and remove the double-sided adhesive tape on the back of the door sensor (or use the screw mounting) to stick it to the door or window. Be sure to remove the insulating paper before using the sensor.
