Qualirey Solar Motion Sensor Alarm 129dB Outdoor Siren

The Qualirey Solar Sound and Light Alarm is a weatherproof outdoor motion-activated siren with a 129 dB horn and strobe LEDs that deter intruders using solar power or DC backup.

Designed for yards, driveways, farms and small business perimeters, this two-piece kit combines a wide-angle passive infrared sensor with bright flashing LEDs and a loud siren to warn off trespassers. Each unit is compact, mounts easily on a bracket, and offers selectable operation modes so you can balance visibility, noise, and energy use. Built to withstand rain and sun, the system is made from rugged ABS housing and stainless steel hardware so it keeps working in outdoor conditions.

How far will the sensor detect movement?

The built-in PIR motion detector has a 125° field of view and reliably senses human-sized movement at about 5–8 meters (16–26 feet). Detection depends on placement, angle, and ambient temperature, so positioning the unit to face the driveway or entry path improves performance.

• 125° motion sensing angle for wide coverage
• Typical detection range: 5–8 meters
• Ideal mounting height: position for clear line-of-sight across entry routes
• Works best when the sensor faces towards expected motion

How loud and visible is the alarm for deterrence?

This siren produces up to 129 dB of sound, loud enough to draw attention across a large property, while six high-intensity LEDs create a bright strobe visible at long distances. The combined audio-visual output is intended to alert neighbors and scare off intruders without requiring a wired security system.

• 129 dB audible alarm, audible up to around 1000 meters in open areas
• Six LEDs produce intense strobe flashes for strong visual deterrence
• Sound and light activate simultaneously when motion is detected (depending on mode)
• Useful for rural properties, driveways, and business perimeters

What power options and operating modes are available?

Each unit is solar-powered with an internal battery and also supports DC charging for continuous use when sunlight is limited. There are four selectable modes to match your needs: continuous day/night flash with alarm, continuous flash without alarm, night-only flash with alarm, and night-only flash without alarm.

• Solar charging for low-maintenance operation
• Optional DC charge input for backup or low-sun periods
• Four modes: full-time alarm, flash-only, night alarm, night flash-only
• Battery life: extended runtime—single full charge can last up to 30 days depending on settings

Is the unit weatherproof and easy to install?

The alarm is built with weather resistance and simple mounting in mind—IP65-rated housing and a stainless steel bracket let you mount it outdoors without worry. Installation is straightforward: attach the bracket, secure the unit, set the desired mode, and angle the solar panel toward sunlight.

• IP65 rated against rain and dust for outdoor durability
• Stainless steel bracket and rugged ABS case for long-term use
• Compact dimensions: 2.72 x 2.91 x 4.72 inches (approximate)
• Includes user manual; hang where the solar panel receives direct sun

Who is this for? The Qualirey Solar Sound and Light Alarm is suited for homeowners, small farmers, rental property managers, and business owners who want a quick, low-maintenance way to protect driveways, gates, sheds and open yards. If you need a portable, hard-hitting deterrent that doesn’t require wiring or a monitoring contract, this solar motion siren delivers a visible and audible presence to discourage theft and trespass.
