## At a glance

- Five modes include welcome, doorbell, alarm, colour light and lighting options.
- The listing claims 36 tunes, four volume levels and alarm volume up to 113dB.
- Colour-light and lighting modes are described as silent, with four brightness levels. The colour-light mode has four selectable colours.
- The receiver can be paired with up to 32 motion sensors and 8 remotes, according to the listing.

## Pros

- Multiple chime and alert modes let the receiver serve as a visitor chime as well as a motion alert.
- Silent light modes provide a visual notification option without an audible alert.
- The listed pairing capacity allows additional compatible sensors and remotes to be added, though these are not established as part of this model's kit.

## Cons

- The infrared sensor is specified for indoor installation only, so it is not presented as an outdoor sensor.

## Before you buy

- The listing gives a battery-life figure of 2640 Hours but also describes 5 to 7 months based on 30 activations per day. Its temperature details are inconsistent, with 1E+1 Degrees Celsius listed alongside 60 Degrees Celsius. The claimed 280 Metres is an open-space transmission range, while the sensor detection range is listed as 2 ~ 8m. Confirm the selected listing's specifications and bundled items before buying. The sensor is described as indoor-only.

## A good fit for

- People wanting a battery-powered indoor motion alarm with a receiver and remote.
- Shops or homes that would use a choice of welcome chimes, doorbell alerts, audible alarms or silent light notifications.
- Buyers who may want to pair additional compatible motion sensors or remotes later.

## Less suited to

- Buyers needing a sensor specified for outdoor installation.
- Anyone requiring a confirmed battery runtime, as the listing provides differing battery-life descriptions.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller spread across lower star levels means the overall figures do not establish that every buyer had the same experience. There is no supplied written feedback identifying particular strengths or problems. For a buyer choosing this unit for its chimes, alert modes or wireless range, the ratings alone cannot confirm how well those features perform in their setting.

## Frequently asked questions

### What comes with this NineLeaf model?
The model name identifies one sensor, one receiver and one remote. The feature description says batteries and a USB-C cable are not included. Check the selected listing for its package details.
### Can the sensor be used outdoors?
The installation information describes the infrared sensor as intended for indoor installation only.
### How far does the wireless system reach?
The listing claims a transmission range of up to 280 Metres in open space. It separately gives a sensor detection range of 2 ~ 8m, so these figures describe different ranges.
### Does it need batteries?
The listing specifies 3 x AAA alkaline for the sensor and 3 x AA alkaline for the receiver. It also mentions Micro-USB power, but says the USB cable is not included.
