Qualirey Solar Outdoor Motion Sensor Alarm — 2 Pack, 129dB Siren & Red‑Blue Strobe Lights

Qualirey Solar Outdoor Motion Sensor Alarm is a weatherproof, solar-powered 2-pack of motion-activated deterrents that combine a 129dB siren, 13 selectable sounds and red-blue strobe lights to repel animals and intruders.

These two compact units run on built-in rechargeable batteries charged by the integrated solar panels, so you avoid frequent battery swaps. Designed for outdoor use, each alarm offers four working modes that mix motion sensing, audible tones and flashing lights to create a visible and audible barrier across gardens, yards, farms and fences.

How does the solar motion sensor work and stay powered?

Each alarm contains a solar panel and a 3.7V 1200mAh polymer battery that stores daytime energy for night and low-light operation. The motion detector triggers the selected sound and strobe sequence when it senses movement within its detection zone.

• Solar panel charges the internal battery during daylight for off-grid use.
• 3.7V 1200mAh battery for extended runtime and cold-weather reliability.
• Motion sensor activates sounds and lights on detection to conserve power.

Which sounds and modes are available, and when should I use each?

The alarm features a library of 13 distinct sounds — including sirens, barking dogs and simulated gunshots — and four operating modes to suit different needs and times of day. Pick continuous 24-hour deterrence or night-only activation to match wildlife patterns and neighborhood comfort.

• Mode 1: 24-hour motion sensor with 13 sounds plus red/blue flashing.
• Mode 2: 24-hour motion sensor with flashing lights only (no sound).
• Mode 3: Night-only motion sensor with 13 sounds and flashing lights.
• Mode 4: Night-only motion sensor with flashing lights only.

How effective is the alarm at deterring animals and intruders?

The combined use of a 129dB alarm tone, varied aggressive sound options and bright red-blue strobe lighting creates a convincing deterrent that startles wildlife and draws attention to suspicious movement. The varied sound library prevents habituation by changing the stimulus each time the sensor is triggered.

• 129dB peak volume provides a loud, attention-grabbing warning.
• 13 sounds reduce the chance animals or people become used to a single cue.
• Strobe lights add visible deterrence during daytime and night.

Where and how can I install these alarms for best coverage?

Each unit ships with mounting accessories so you can place it on the ground, attach it to a fence post, or mount it on a wall. Position units to face likely approach routes, keep solar panels angled toward the sun, and space the two alarms to overlap detection zones for wider protection.

• Mount on fences, posts, walls or stake into soil for flexible placement.
• Angle solar panels toward midday sun for optimal charging.
• Space units to cover different access points and reduce blind spots.

Who is this for: The Qualirey Solar Outdoor Motion Sensor Alarm 2-pack suits homeowners, smallholder farmers, orchard keepers and anyone wanting a low-maintenance, solar-powered deterrent for animals and unwanted visitors. It’s built for outdoor conditions, simple to set up, and useful where mains power isn’t available or where you prefer a non-lethal, attention-getting solution.
