Expandable Waterproof Wireless Doorbell - Loud Alert System, Starter Kit

The 52 Premium Chimes doorbell system offers a patent-pending sound chip that delivers the largest premium selection of real ding-dong chimes without any annoying or "tinny" childish melody ringtones. With an effective long operating range of over 1000 ft in open areas and the ability to operate through walls and doors, this system is ideal for large homes, apartment buildings, offices, or warehouses.

The system boasts an ultra-long battery life, with the transmitter button's battery lasting up to 3 years on low usage, 1-2 years on medium usage, and up to 1 year on high usage. The weatherproof and waterproof design ensures the system can function in all weather conditions, from -4°F to 140°F.

The doorbell system features four volume levels up to 115dB, providing ample loudness when needed, as well as a convenient low-level setting for quieter areas. The smart memory function retains the chime and volume settings during power outages, eliminating the need to reconfigure the doorbell settings if the receiver is unplugged.

Aesthetically, the system offers a range of vivid color options, including White, Black, Matte Black, Grey, Beige, Blue, Yellow, Red, and Green, ensuring the doorbell button can be easily noticed and integrated into any decor.

The versatile and expandable nature of the system allows users to build their own simple alert system, with the ability to add up to 20 additional buttons, receivers, or sensors. This product has been featured on various news outlets, such as Business Insider, FOX, ABC, NBC, and CBS, with one reviewer stating, "It's built well, and it has a nice minimalist style."

The base start kit includes two plugin receivers, two remote transmitter buttons, double-sided stickers, anchors, screws, and an A23 battery. Customers can also listen to the 52 available ringtones before making a purchase by downloading the provided PDF file.
