Qualirey Solar Outdoor Siren Motion Alarm 2-Pack (Red) — 129 dB, IP65 Weatherproof with Strobe LEDs

Qualirey Solar Sound and Light Alarm is a weatherproof, solar-powered outdoor siren with motion detection and 129 dB deterrent sound paired with strobe LEDs to warn and alert at long range.

Designed for yards, driveways, farms and remote properties, this two-pack system combines a bright strobe, a loud horn and a 125° motion detector to discourage intruders and notify nearby residents. Each unit runs on a built-in solar panel with optional DC charging, mounts on a stainless steel bracket, and is built to withstand rain and wind with an IP65 rating. Multiple operating modes let you balance visibility and noise to suit daytime or nighttime use.

How far will the motion sensor and alarm reach?

The built-in passive motion sensor covers roughly 5–8 meters with a 125° detection arc, good for typical driveways and garden approaches. When triggered, the siren produces up to 129 dB and the strobe array is visible at long distances, providing both audible and visual warning.

• Motion detection range: about 5–8 m (16–26 ft)
• Sensor angle: approximately 125°
• Alarm volume: up to 129 dB for strong deterrence
• Strobe visibility: designed to be noticeable from extended distances

What power options and running time can I expect?

Each alarm charges via its integrated solar panel and supports optional DC charging for cloudy areas or indoor charging prior to installation. A full solar charge can sustain operation for many nights; actual duration depends on sunlight exposure and selected mode.

• Primary charging: built-in solar panel — place where sunlight is available
• Alternative charging: DC input for faster or backup charging
• Battery life: extended standby and multi-night operation with normal sunlight
• Recommendation: mount high and tilted toward sun for best performance

Which operating modes are available and how do they help?

The unit offers four practical modes so you can choose continuous strobe, siren plus strobe, or night-only variations. This lets you prioritize visibility, reduce daytime nuisance noise, or limit activation to darkness when stealthier detection is needed.

• 24-hour flash + alarm: constant protection with sound and strobe
• 24-hour flash only: visible deterrent without noise
• Night flash + alarm: activates only after dusk with sound and strobe
• Night flash only: nighttime strobe visibility without the horn

How durable and easy to install is the system?

The housing uses rugged ABS plastic and a stainless steel mounting bracket rated IP65, so it tolerates rain, dust and outdoor conditions. Installation is straightforward with the included instructions and hardware, and the compact dimensions make it suitable for walls, posts or eaves.

• Weatherproof rating: IP65 for dust and water resistance
• Materials: ABS housing and stainless steel bracket for durability
• Mounting: simple wall or post installation with included hardware
• Unit size: compact dimensions for flexible placement

Who is this for? If you need a visible and audible deterrent for small-to-medium properties — such as homes, farms, driveways, garages and outbuildings — the Qualirey 2-pack offers a cost-effective, low-maintenance option. It suits homeowners who want a solar-powered alarm that’s easy to mount, provides multiple mode choices, and holds up in outdoor conditions. Installers and property managers who need remote or off-grid coverage will also appreciate the solar charging and optional DC input for backup. While it strengthens perimeter awareness, pair these alarms with lighting and cameras for a layered security approach.
