Frequently Asked Questions

Q: How does the wireless motion sensor doorbell work?

A: The transmitter (sensor unit) detects motion using a built-in PIR sensor and wirelessly sends a signal to the plug-in receiver, which then chimes an audible alert. There is no wiring needed between the two units — simply place the sensor near your entrance and plug the receiver indoors.

Q: Is the sensor unit weatherproof for outdoor use?

A: Yes — the transmitter/sensor unit is waterproof and designed to withstand splashes and rain, making it suitable for outdoor mounting at doors, driveways, and entrances.

Q: What batteries does the sensor require, and how long do they last?

A: The transmitter runs on 3 × AAA batteries (4.5V total). Battery life will vary depending on how frequently motion is detected, but the low-power sensor design helps maximise battery longevity.

Q: Can I use this doorbell in my retail store or office?

A: Absolutely. This wireless motion sensor doorbell is well-suited for retail stores, banks, offices, and any commercial space where you need to be alerted when someone enters. The adjustable volume lets you set the chime level to suit your environment.
