Wireless Motion Sensor Door Chime with 36 Songs and 4 Volumes
A shop door opens while you are stacking a shelf at the back, and the chime on the wall sounds. This set pairs an infrared motion transmitter with a mains-powered receiver, plays 36 melodies at four volume steps and reaches 200 m in the open. It suits small shops and offices.
A Chime in the Room, Not Just at the Door
✅ No cable between the units The transmitter and receiver are linked by radio, so nothing has to be run from the doorway to the counter.
✅ Fitted where people pass The sensor is aimed across a doorway or corridor, at the height where someone walking through enters its field.
✅ Two receivers, two rooms The maker gives the receiver as a set of two, so a chime can sit at the counter and in the back.
✅ A sound for the setting Thirty-six melodies and four volume steps let a quiet consulting room and a busy loading bay use different settings.
✅ Heard across a warehouse The radio link is given for up to 200 m in open ground, so the chime can sit far from the entrance.
Setting it up is two separate jobs. The transmitter goes where people pass, aimed across the opening at roughly the height of a walking adult, and the receiver goes wherever the sound is needed, plugged into a socket. Radio links the two, so the distance between them is a matter of range rather than cabling.
Range figures deserve care. The 200 m applies to open ground with nothing in the way; indoors the maker gives 85 m where the path is clear, and walls, shelving and metal racking shorten it further. The pair is described as usable in a two-storey building, but the receiver is best kept on the same floor as the entrance it serves.
It is a chime, not an alarm system. The transmitter reacts to movement in its field of view and the receiver plays the melody you have chosen; nothing is recorded, nothing reaches a phone, and the sensor does not tell a customer from a courier. It makes a sound in a room, which is what the set is for.
The receiver runs from mains power, certification is given as CE, RoHS and PSE, and the set is described as two receivers with the transmitter. Voltage and plug type are not stated, so check the socket where the receiver will go before you order.
