Overview
A contact sensor on a door sends a signal whenever the door opens, and the receiver then plays a chime from a menu of tones. Tape or screws mount the sensor, which runs on a small battery, and the product is aimed at bedrooms, businesses and care situations.
The reason to buy is the wide chime and volume choice with a loud rated output. The limitation is mismatched range figures, and the receiver must stay near an outlet.
Who it's for
Parents of toddlers, caregivers and shop owners who want to hear a door open will use the chime. Anyone needing security alarm features or phone alerts should buy a full alarm system.
Pros and cons
- Many chime choices
- Several volume levels
- Includes sensor battery
- Mounting hardware included
- Range figures conflict in listing
- Receiver needs an outlet
- Not a security alarm
Performance notes
Opening the door triggers a wireless signal, and the chime plays at the chosen volume. Walls and distance reduce range, so the listed figure is a best case. Sensor battery life depends on how often the door opens.
