KERUI Wireless Indoor Motion Sensor Doorbell with Visitor Alert for Businesses

Everything You Need To See

♫ Brief Introduction:

This standalone, all-in-one chime alarm combines motion detection with a 90db alert and flashing red light, offering a reliable detection range of 2-6M in open areas. Perfect for shops, offices, homes, and businesses, it alerts you of intruders or visitors with ease and efficiency.

Main Function:

With a mode button for selection, this chime alarm offers three modes: voice, alarm, and music. In voice mode, it greets with "Dingdong, hello, welcome." The alarm mode provides continuous sound for about 15 seconds. Choose music mode to play from a library of 32 options, adjusting the volume with ease.

Power Supply:

You can power this doorbell chime with a 9-15V power adapter or 3 AAA batteries (not included). Batteries offer more convenience and a longer operational time, while the adapter provides a more flexible installation.

Easy Installation:

The chime motion detector has a horizontal detection angle of 110° and a vertical angle of 15°. Installation is straightforward via 2 screws and double-sided tape. Place the battery and adjust the angle to minimize false alarms, but avoid outdoor use. If the product doesn't respond or has issues, adjust the angle or replace the battery.

Attention & Warranty:

In any mode—voice, alarm, or music—the chime cannot be turned off or powered down until it finishes its function and the red light stops flashing, or settings will reset. We offer a 12-month warranty, and you can get technical support and responsive customer service within 24 hours. Reach out to us via Amazon email for any questions.
