Wireless Doorbell with Intercom, Rechargeable Battery, Waterproof & LED Flashlight

The SANZUCO wireless doorbell is a full-duplex intercom system that provides convenience and enables seamless hands-free two-way communication between users and their visitors. Simply press the "Call" button on the outdoor transmitter, and then the "Answer" button on the indoor receiver to initiate the conversation, leaving your hands free.

Utilizing high-frequency electrical technology and an FM signal protocol, this doorbell offers robust anti-interference protection, ensuring it will not disrupt other nearby wireless devices or interfere with neighbors. In an unobstructed environment, the sensing distance can reach up to 1000 feet. Additionally, the multifunctional wireless doorbell can also be used as a pager to cater to your diverse needs.

The doorbell receiver's battery can be used for 4 to 5 days on a full charge, while the transmitter's battery can last for up to 4 months when fully charged. It's important to note that the charging stand does not contain a battery and requires a charging cable to be connected for use.

Our wireless doorbell can be extended to multiple transmitters and receivers, and can be configured with different ringtones for each door, allowing you to tailor the system to your home or office requirements. The doorbell offers 4 ringing tones and 8 volume levels, ensuring you can hear the clear and loud sounds no matter your location. The colored LED indicator lights are also beneficial for individuals with hearing impairments, making it a perfect wireless doorbell for the elderly.

The SANZUCO wireless doorbells for home come pre-paired, eliminating the need for wiring or electrician installation during use. The indoor receiver unit is set to the "off" mode upon delivery, and users simply need to press and hold the ON/OFF key for 3 seconds to activate the indoor unit. To facilitate transportation and protect the doorbell batteries, the devices are not fully charged upon arrival. However, we recommend fully charging the transmitter and receiver before initial use to ensure optimal performance.

In the event of any issues with the wireless doorbell, users can easily troubleshoot common problems. If the doorbell doesn't work, check whether the indoor receiver is turned on, and ensure that both devices are fully charged. If the transmitter and receiver cannot hear each other's voice, verify that the two devices are set to the same channel. If you encounter any other problems, our professional service team is available to provide support.

The SANZUCO wireless doorbell is designed with high-quality ABS material and can withstand a working temperature range of -4°F to 140°F. It also boasts IP55 waterproof protection and LED light indicators, making it a reliable and versatile choice for your home, classroom, or office needs.
