From the brand, Bistee is a company specializing in security and household products, established in China for 30 years, with mature and stable technology in product quality and function. All Bistee customers can enjoy lifetime after-sales service, and the company welcomes any questions about orders and products.

The Bistee Wireless Doorbell Chime features 58 chimes and 5 adjustable volume levels (0 dB to 110 dB) to suit various occasions. The LED indicators are suitable for the elderly and hearing-impaired, and the doorbell remembers the last melody and volume level after a power outage, eliminating the need to reset.

With a range of up to 150 m/600 ft in open areas, the doorbell's signal can easily cross through doors or walls, ensuring you never miss a visitor, even if you are a few rooms away or on another floor. However, the battery level can affect the signal range, and it is recommended to change the battery once every 12 months.

The doorbell's expansion system includes a door/window sensor that detects every entry and sends an alarm warning to the doorbell chime receiver, better protecting your property. You will hear the doorbell chime to remind you when someone opens your door/window or your pet comes home. Each door sensor or receiver can be expanded for business, home, apartment, classroom, office, basement, and more.

Installation is easy: just plug the wireless doorbell into a socket, peel off the tape behind the door sensor chime, and paste it on the door. The wireless door chime has been pre-matched before shipment. If you need to replace the music or add a transmitter, you can re-match by holding the receiver's music button for 3 to 5 seconds to trigger the clean pairing function.

Bistee's wireless doorbell is a brand with years of independent R&D and is approved by FCC, CE, RoHS, and other certificates. Customers can benefit from a 30-day money-back guarantee and a passionate after-sales service team, available to assist with any problems.
