Door Chime,SanJie Wireless Door Sensor Chime When Door

Product Overview

The SanJie Wireless Door Sensor Chime offers a reliable, long-range solution for monitoring door activity in both home and business environments. Designed to provide instant alerts when a door opens, this system is ideal for parents keeping an eye on children, store owners tracking customer entries, or anyone who needs clear notification of entry events—without needing constant supervision. With a transmission range of up to 500 feet, it ensures coverage across large properties, warehouses, offices, or multi-level homes. Each receiver can connect to an unlimited number of magnetic sensors, allowing you to monitor as many doors as needed without signal interference. The system also supports pairing different chimes to individual sensors, so you’ll always know exactly which door was opened—whether it’s the front entrance, back exit, delivery dock, or side gate.

Key Features

• Long Range Connectivity: Operates effectively over a 500-foot range, making it suitable for large homes, offices, retail spaces, or industrial facilities where receivers may be located far from monitored doors. This ensures reliable communication even through obstacles like walls or floors.
• Unlimited Sensor Pairing: Each receiver can be paired with an unlimited number of magnetic door sensors, enabling comprehensive monitoring of multiple entry points simultaneously. Whether you’re securing one door or dozens, there’s no limit to how many you can add.
• Customizable Ringtone Selection: Supports pairing 26 distinct chime tones to individual sensors. This feature allows users to assign unique sounds to each door—such as a soft melody for the child’s room or a louder alert for the main entrance—so you instantly identify which door was triggered.
• LED Status Indicators: Built-in LED lights on both the receiver and sensors provide visual confirmation when a door opens or when the system is powered and connected. This improves reliability and gives immediate feedback beyond just sound.
• Memory Function: Retains previously selected chime settings even after power cycles. Once you set your preferred tone or volume, the system remembers it automatically, eliminating the need to reconfigure every time the device is unplugged or restarted.
• Adjustable Volume Control: Features five levels of volume adjustment—from low (for quiet environments like bedrooms) to high (for noisy commercial areas). This flexibility ensures optimal performance whether used in a nursery, office, warehouse, or storefront.

Benefits & Use Cases

The SanJie Wireless Door Sensor Chime enhances safety, security, and operational efficiency across a wide range of applications. Homeowners benefit from peace of mind knowing they’ll hear when their kids arrive home, pets enter restricted areas, or deliveries are made at the door—even if they’re upstairs or outside. Parents can use it to monitor toddlers learning to walk or young children exploring the house unsupervised. In commercial settings, business owners gain valuable insight into customer traffic patterns, employee movements, and delivery arrivals without needing staff stationed at every entrance.

One of the standout advantages is the ability to assign different chimes to different doors. For example, a small shop might pair a cheerful tune to the main storefront and a deeper tone to the stockroom entrance—making it easy to distinguish between customers and employees. Similarly, a parent can differentiate between the front door (used by adults) and the backyard gate (used by children). This targeted feedback streamlines response times and improves situational awareness.

The system’s expandability means you start with two sensors but can add more anytime without upgrading your receiver. This makes it cost-effective for growing needs—whether expanding a home security setup or outfitting an entire retail space. The memory function further enhances convenience by preserving your custom settings through power outages or routine maintenance.

Important Notes

The package includes two magnetic door sensors and one receiver unit. No additional hardware is required beyond standard installation. Ensure the receiving unit is plugged into a nearby electrical outlet within effective range of all sensors. For best performance, avoid placing metal objects directly between sensors and the receiver, as this may interfere with signal transmission.

While the system supports unlimited sensor connections in theory, actual reliability may vary based on environmental factors such as thick walls, large furniture, or electronic interference. For optimal results, position the receiver centrally and ensure clear line-of-sight or minimal obstruction to monitored doors. Batteries for the sensors are not included and should be purchased separately according to the device specifications.
