• 38 Ringtones & 4 Volume Levels: Choose from 38 distinct chimes and set volume to low, medium, high, or silent (LED-only) mode — so you get the alert style that suits your household without startling anyone unexpectedly.
• Dual Alert Signals: Each alarm triggers both an audible chime and a LED light flash, ensuring you never miss an alert even in noisy environments or when sound is muted.
• Flexible Configuration Options: Available in 4 package configurations (4 sensors + 2 receivers, 2 sensors + 1 receiver, 1 sensor + 1 receiver, 1 sensor + 2 receivers) and 3 plug types (US, UK, EU) to suit your setup.

Installation Tips for Best Performance

• Mount the sensor at approximately 2 meters (6.5 ft) in height for optimal detection coverage.
• Install the sensor at the side or top of an entryway rather than facing it straight-on — lateral detection is more sensitive.
• Avoid placing the sensor near heat sources (vents, stoves, heaters) or in direct sunlight to minimize false triggers.
• Keep the area between sensor and receiver as clear as possible; through walls, limit the distance to approximately 20 meters for reliable signal.
• Note: The motion sensor is not waterproof — install in covered or sheltered outdoor locations to protect from direct rain exposure.
• In high ambient temperatures (above 30°C / 86°F), detection distance may be slightly reduced — this is normal.

Frequently Asked Questions

Q: What is the wireless range of this motion sensor doorbell alarm system?

A: This wireless motion sensor doorbell system has a maximum signal transmission range of 300 feet in open space between the motion sensor and the receiver. The PIR infrared sensing distance of the detector itself is up to 20 feet. Note that walls and obstructions may reduce effective range — through a single wall, it is recommended to keep the sensor and receiver within approximately 20 meters.

Q: Does the motion sensor doorbell work outdoors?

A: The system is designed for both indoor and outdoor use, but the motion sensor is not waterproof. For outdoor installation, place the sensor in a sheltered or covered location to protect it from direct rain. Avoid mounting in direct sunlight or near heat sources such as vents or heating units, as these may cause false triggers.

Q: How many ringtones and volume settings does the receiver offer?

A: The receiver features 38 selectable ringtones and 4 volume settings: Low, Medium, High, and Silent (LED-only mode). The volume output ranges from 20dB up to 85dB, giving you flexible control to suit any environment — from a quiet bedroom to a noisy garage.

Q: What batteries does the motion sensor require?

A: Each motion sensor transmitter requires 3 × AAA batteries (4.5V total), which are not included in the package. The plug-in receiver operates on standard household current (110–240V) and does not require batteries.

Q: Can I use this system for multiple entry points around my home?

A: Yes! This system supports multiple configuration options — you can choose packages with up to 4 sensors and 2 receivers, allowing you to monitor several locations (front door, back door, driveway, garage) simultaneously from one or more receivers placed in different rooms.
