- 【Door Chime Alerts You Instantly When Door Opens】Never miss a moment that matters — this wireless door sensor chime triggers an immediate 110dB alert the second any door or window opens. Perfect for parents keeping toddlers safe, caregivers monitoring elderly with dementia from wandering, or pet owners preventing escapes. Whether it's a bedroom, backyard gate, or front door, you'll know the moment it opens — giving you peace of mind even when you're in another room.
- 【Smart Entry Alert for Stores, Offices & Restaurants】Transform your retail shop, salon, pharmacy, or café with a professional entry chime that notifies you the moment a customer walks in — so you never miss a sale or leave a guest waiting. Assign digital labels (1–9) to different entrances, so you always know which door was triggered. Ideal for single-staff businesses, back-office workers, or anyone managing multiple entry points without a dedicated receptionist.
- 【1000Ft Long Range Covers Every Corner of Your Home or Business】With a wireless transmission range of up to 1000 feet (300 meters open field), this door chime system ensures reliable signal penetration through multiple walls and floors — covering large homes, multi-story buildings, warehouses, and commercial spaces without dead zones. Each sensor pairs with its own unique digital code so you always know exactly which entry was triggered. Plug in multiple receivers throughout your space to ensure you hear the alert everywhere — kitchen, garage, basement, or back office.
- 【55 Ringtones, 5 Adjustable Volume Levels & LED Indicator】Choose from 55 classic and melodic ringtones to match your home décor or business atmosphere — from gentle chimes to energetic alerts. Volume ranges from silent (0dB) to loud alarm (110dB) across 5 levels; the LED indicator provides a silent visual alert for quiet environments like bedrooms, libraries, or nurseries. Memory function retains your preferred ringtone and volume even after power outages — no need to reprogram after every outage.
- 【Pre-Paired & Ready to Use — Expandable to 64,000 Coded Sensors】Out of the box, the receiver and sensor are already paired — simply plug the receiver into any standard outlet, peel the adhesive backing, and stick the sensor to your door. No wiring, no drilling, no electrician needed. Need more coverage? This system supports pairing with up to 64,000 uniquely coded sensors, making it future-proof for growing families, multi-unit properties, or expanding businesses. Available in 6 bundle configurations (1 to 4 sensors, 1 to 2 receivers) to match your exact coverage needs.
