Ranxinyuan Dog-Bark Motion Alarm 3-Sensor Outdoor Kit — PIR Weatherproof Sensors, 110 dB Receiver

This wireless motion-activated security kit combines three weatherproof PIR sensors with one powered receiver that plays six different dog-bark sounds at adjustable volumes up to 110 dB. Sensors are battery-powered for flexible placement around doors, gates, garages or yards, and the receiver plugs into a standard outlet with a USB lead included. The system ships pre-paired so you can install and protect a perimeter in minutes without complex wiring.

How loud and customizable is the alarm?

The receiver uses a built-in audio amplifier and offers four volume levels, letting you pick a gentle warning or a very loud deterrent. Maximum output reaches approximately 110 dB, suitable for outdoor areas and long driveways where a clear audible alert is required.

• Four user-selectable volume settings for day or night use.
• Six realistic dog-bark sound options to vary deterrent effect.
• Receiver plugs into mains via included USB cable for continuous power.
• High-volume mode suitable for open yards and perimeters.

Where can I mount the sensors and what powers them?

Each sensor runs on three AA alkaline batteries (not included), enabling cordless placement on fences, walls, trees, doors or window frames. Mounting is fast: use the supplied double-sided tape for temporary placement or screws for a secure, long-term installation.

• Battery-powered sensors for flexible, wireless placement.
• Waterproof housing suitable for outdoor exposure.
• Mount with adhesive or screws depending on surface and permanence.
• Pre-paired receivers and sensors reduce setup time to minutes.

How reliable is motion detection and wireless range?

The upgraded PIR sensor and refined infrared chip improve sensitivity and help reduce false alarms from weather changes like fog or sunlight. Line-of-sight wireless transmission can reach up to 1000 ft, although obstacles and environmental conditions will affect that distance.

• Enhanced infrared detection for fewer false triggers.
• Wireless transmission range up to 1000 ft in open conditions.
• Detection optimized for human-body motion rather than small animals.
• Temperature and humidity may influence detection sensitivity.

Can multiple sensors be differentiated and expanded?

Yes—each sensor can be matched to the receiver so different chimes indicate where motion was detected, which helps pinpoint the triggered location around a property. The system supports multiple chime mappings so you can add sensors to cover separate entry points and know which area needs attention.

• Assign unique chimes to sensors to identify trigger locations.
• Expandable arrangement for more coverage around buildings and grounds.
• Pre-programmed pairing simplifies adding extra sensors.
• Works well for doors, gates, garages and yard perimeters.

Who is this for? Homeowners, renters, small business owners and property managers who want an affordable, easy-to-install deterrent system will find this Ranxinyuan kit practical. It suits people who need a non-invasive security layer that doesn’t require professional wiring—ideal for outer doors, driveways, sheds and open yards. If you want an audible, animal-sound deterrent with flexible sensor placement and a plug-in receiver for continuous alerting, this kit provides a quick, weather-resistant solution.
