Frequently Asked Questions

Q: Does the solar motion sensor alarm work at night without sunlight?

A: Yes! The built-in 3.7V/400mAh lithium-ion battery stores solar energy during the day and powers the alarm at night. After a full charge (6–8 hours of sunlight), it can handle over 300 alarm triggers of 45 seconds each, making it reliable for 24/7 outdoor security coverage.

Q: Will my pets trigger the solar motion alarm?

A: No — the alarm features smart pet-immune PIR technology that recognizes and ignores animals under 25 kg (approximately 55 lbs). This means your dogs, cats, or other small pets can roam freely without setting off the siren, while the sensor remains fully alert to human-sized movement.

Q: Is this motion sensor alarm truly waterproof for outdoor use?

A: Absolutely. The device carries an IP65 waterproof rating, meaning it is protected against dust ingress and water jets from any direction. It is designed for year-round outdoor installation and can withstand rain, garden hose splash, morning dew, and humidity without damage.

Q: How do I install the solar-powered alarm?

A: Installation is straightforward — simply use the included mounting hardware to screw the device onto a wall, fence post, or any flat surface. No wiring or electrician is required. Position the solar panel toward direct sunlight for optimal daily charging, and aim the sensor toward the area you want to monitor.
