WONFAST Solar Motion Sensor Alarm 130dB Strobe

WONFAST Solar Outdoor Motion Sensor Alarm is a solar-powered, recordable 130dB dual-speaker security strobe that detects movement and plays one of 13 built-in sounds or your own recording.

This weatherproof strobe-and-siren unit combines bright flashing lights, two 130dB speakers, and customizable audio to deter animals and intruders on farms, orchards, yards and outbuildings. It charges by solar panel or DC cable, offers multiple trigger modes and adjustable volume levels, and stores user recordings up to 15 seconds so you can tailor alerts to your property and neighbors.

How does the motion detection and trigger modes work?

The built-in PIR motion sensor activates the alarm and strobe according to one of four selectable operating modes. Choose continuous day/night detection, flashing-only modes, or night-only activation to match how you want the unit to respond to movement.

• Mode A: 24-hour motion-triggered sound and flashing.
• Mode B: 24-hour motion-triggered flashing only.
• Mode C: Motion-triggered sound and flashing at night only.
• Mode D: Motion-triggered flashing at night only.

What sound and volume options are available?

Two high-output 130dB speakers produce powerful alerts with three selectable volume settings so you can reduce nuisance noise or maximize deterrence. The system includes 13 factory sounds and a recording function to upload a custom 15-second message for specific situations.

• Adjustable volume: 99dB, 125dB, or 130dB.
• 13 preset sounds: e.g., gunshot, dog bark, lion roar, siren, horn and more.
• Record custom audio through the built-in microphone (up to 15 seconds).

How is the unit powered and how long does it run?

The WONFAST alarm uses a 2000mAh rechargeable battery that charges via the integrated solar panel or with DC charging for cloudy days and faster top-ups. A full solar charge typically provides a day of active operation and can maintain standby power for months depending on settings and sunlight.

• Dual charging: solar panel or DC cable input.
• 2000mAh internal battery for extended standby and daily use.
• 8–10 hours of solar charging for a full cycle; long standby life up to roughly 3 months in low-activity conditions.

Is this alarm suitable for outdoor agricultural or property use?

The enclosure is made from durable ABS plastic and rated IP65 for dust and water resistance, making it fit for exposed outdoor locations like barns, orchards, farm gates and yards. Its combination of bright strobe and loud, varied audio makes it effective for deterring wildlife, stray animals and potential intruders without needing mains power.

• IP65 weather resistance protects against rain and dust.
• Robust ABS housing for outdoor durability and long-term placement.
• Wide application: farms, garages, courtyards, villas, schools and industrial sites.

Who is this for: The WONFAST Solar Outdoor Motion Sensor Alarm is aimed at homeowners, farmers and small business owners who need an off-grid, weatherproof deterrent with flexible audio options. It suits anyone who wants an adjustable-volume, solar-powered siren and strobe that can play preloaded or custom sounds to protect outbuildings, livestock areas, gates and property perimeters without hardwiring.
