Bistee is a company specializing in security and household products, with a history of 30 years in China and mature, stable technology in product quality and function. All customers of Bistee can enjoy lifetime after-sales service, and are encouraged to contact the company's after-sales service with any questions about orders and products.

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

With a range of 150 m/600 ft in open areas, the doorbell's signal can easily penetrate doors and walls, ensuring users never miss a visitor, even if they are in a different room or on another floor. However, the battery level can affect the signal range, and it is recommended to replace the batteries once every 12 months.

The doorbell system can be expanded with door/window sensors, which will detect every entry and send an alarm warning to the doorbell chime receiver, alerting the user to the presence of a visitor or a pet entering the home. Each door sensor or receiver can be installed in various locations, such as business premises, homes, apartments, classrooms, offices, and basements.

Installation is straightforward, with the wireless doorbell simply needing to be plugged into a socket, and the door sensor chime adhered to the door using the provided tape. The wireless door chime has been pre-matched before shipment, but if users need to replace the music or add a transmitter, they can easily re-match the device 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 that has undergone independent R&D and is approved by FCC, CE, and RoHS certifications. Customers can benefit from a 30-day money-back guarantee and a passionate after-sales service team, which can be contacted at any time in case of any issues.
