SECRUI Wireless Door Chime — 2 Receivers, 1 Sensor, 500ft Range

The SECRUI Wireless Door Chime is a door-open alert kit with one door sensor and two receivers. When the door opens, both receivers chime, so you can hear it in two different parts of a home, shop or office. The wireless range is up to 500 ft in open space.

Two receivers make the difference in practice: one at the front counter and one in the stockroom, or one in the kitchen and one upstairs, so someone coming through the door is heard wherever you are.

Setup

No wiring is needed. The sensor sticks to the door and frame with the included adhesive, so you can move it later if your layout changes, and no tools are required. Link both receivers to the sensor, choose a ringtone and volume, then open the door to test.

Sound options

There are 32 ringtones and adjustable volume. A quiet tone suits a nursery hallway or home office; something louder carries across a busy retail floor or a garage.

Typical uses

Retail stores use it to alert staff without relying on one fixed speaker. At home it covers entry doors, back doors and garage access; in offices and hotel lobbies the two receivers can sit in separate zones; and in rentals it tells you when a door is opened.

Getting the full range: the 500 ft figure applies in open air. Walls, furniture, large metal objects and other interference all shorten it, so place receivers in open spots rather than inside metal cabinets or behind thick walls, and test from the far end before settling on a location.
