Wireless Doorbell, Door Alarms for Kids Safety with 4 Sensors & Receiver | Door Alarms when Opened. 500FT Range, 36 Chimes, 5 Volume Levels. Toddler Safety Sensor for Doors/Windows. No Wiring Needed

This wireless doorbell system provides comprehensive coverage for homes and small businesses. With up to 500 feet (150 meters) of open-space range between the receiver and the farthest door sensor, you can expand coverage to every entry. Each door opening triggers a door chime, delivering reliable alerts across the property. The system features 36 chimes and 5 volume levels, plus LED indicators for clear visual alerts. It works as both a door sensor alarm and a window alarm, making it suitable for kid-safe monitoring of doors and windows and for use as wireless doorbells for quick notifications.

Setting up is fast and wire-free. The door sensors come with batteries pre-installed and are factory pre-paired. Attach sensors using the included double-sided adhesive tape, or mount the receiver with screws for a more permanent setup, or simply place it on a tabletop. No wiring is required, so you can position the receiver wherever you want to monitor doors and windows.

For businesses and multi-entry homes, you can assign distinct melodies to different doors so you always know which entry triggered. This kit is ideal for apartments, offices, storefronts, clinics, and any space needing scalable, wire-free door and window alerts. The four variants let you tailor the number of sensors to your space and monitoring needs, ensuring you get exactly the coverage you require.
