SanJie Door Sensor Chime – 500 ft Range, 26 Chimes, 5 Volume Levels, 3 Sensors + 2 Receivers

Smart, flexible door alert for every doorway

The SanJie Door Sensor Chime is a versatile wireless alert system designed to keep track of entrances across homes, small businesses, offices, and storefronts. This kit includes three sensors and two receivers, delivering reliable audible notifications when doors or windows open. With an impressive 500‑foot range, it’s built to cover larger spaces and multi-room layouts, helping you stay informed without being tied to a single room.

Easy setup and dependable operation

Setup is straightforward: sensors and receivers come pre‑paired, so you can install quickly. Simply plug the receivers into a standard outlet and mount the sensors on doors or windows using the included adhesive tape. A memory function keeps your chosen tune after power interruptions, and LED indicators provide a quick visual confirmation of which sensor is active.

Versatile sounds and clear customization

Choose from 26 chimes and tailor the volume with five adjustable levels to suit different spaces—quiet rooms, busy reception areas, or noisy storefronts. A mute option adds flexibility when silence is preferred. Each sensor can be paired with a different ringtone, enabling you to identify which door is triggering the alert at a glance.

Expandable for larger setups

The system is designed with growth in mind: you can expand beyond the included three sensors by adding more magnetic sensors and, if needed, additional receivers. The combination of broad range, multiple devices, and customizable sounds makes it suitable for homes, offices, stores, and other entry points where timely notifications matter.

Everyday use cases

In a residence, the setup can help you notice a toddler slipping out of a bedroom or alert a caregiver if an elderly family member moves toward an exit. In a retail or office environment, it can remind staff when a door is accessed, helping with customer flow and security without being disruptive. The real value lies in a setup that aligns with how you move through your space—effortless to install, simple to customize, and adaptable as your needs evolve.
