Wireless Door Chime for Office/Home/Store

👍【Master Each Area You Care】The door chime signal can easily cross through doors or walls, even if you are a few rooms away or on another floor, with a range of 600ft (150m) – far enough to cover every door and window in your house. Note: The battery level will affect the signal receiving range, and it is recommended to change it once every 8 months.

👍【58 Melodies & 5 Volume】The wireless door chime 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 after a power outage, so there's no need to reset to your previous settings.

👍【Expandable】Each wireless doorbell receiver can pair up to 20 magnetic door alarm sensors, and each sensor can add unlimited receivers. You can use them with additional BITIWEND door sensors or doorbells, installing them in your dining room, bedroom, living room, garage, yard, or your store and office.

👍【Up to 600 FT Working Range】The wireless door sensor chime has a working range of up to 600ft in open areas, ensuring you will never miss a visitor. Note: The battery level will affect the signal receiving range, and it is recommended to change it once every 12 months.

👍【Easy to Install and Use】Simply plug the doorbell receiver into any standard outlet and peel off the double-sided adhesive tape on the back of the door sensor (or screw it in) to stick it to the door or window. Remember to remove the insulating paper before using the sensor.
