Product details

About this item

Description: The infrared doorbell is a smart, battery-powered solution for home and business security. Features: The motion sensor can be mounted on walls or near entrances. It detects movement and instantly sends a signal to the receiver within a 280-meter open-area range, ensuring reliable alerts. The receiver offers 22 voice messages and 8 chime options, with 5 adjustable volume levels. A 40mm metal speaker delivers loud, clear sound up to 96dB. When sensors at different locations (A or B) are triggered, the receiver automatically lights up with different LED colors, allowing visual identification of visitor entry direction, even with the same ringtone. Assign different chimes to different sensors. This makes it easy to distinguish between front door, back door, or shop entrance visitors. Includes a silent vibration alert mode, ideal for quiet environments. The system remembers your settings and automatically restores the last-used ringtone after power loss or battery replacement. Perfect for shop owners or staff working in the back office, helping you stay aware of customer entry without needing constant visual monitoring. The sensor runs on 3x AAA batteries.
