Greencycle Motion Sensor Alarm 2PK — IP65 Waterproof Outdoor/Mailbox Door Alarm, Anti-theft Weatherproof Motion Detector with 900FT Long-Range Ringer for Garage, Driveway, Shop

Compact, weatherproof motion alert system designed for outdoor protection — perfect for driveways, gates, mailboxes, porches, garages and small businesses. Each sensor offers four independent LED zones so you can tell which area triggered an alert, and you can synchronize sound notifications across zones. A new strong, silent vibration reminder is available for discreet alerts. Advanced dual-detection keeps false alarms low: the unit combines infrared + microwave radar technology (composite double detection) and includes a software de-interference algorithm. The probe light can be switched off for stealth monitoring, and the sensor uses a three-layer waterproof design for reliable outdoor use. Coverage and range: the sensor’s detection works from 2-8 meters, with radar detection reaching 6-8 meters (depending on temperature). In open areas the wireless link between sensor and receiver can reach up to 918ft (280m), providing dependable communication over long distances. Expandable and customizable: mix and match transmitters and receivers to suit your property. Assign different lights or ringtones to specific detectors. Each receiver supports up to 32 motion sensors and 8 remotes, giving flexible scalability for larger sites. Power and installation: the receiver can be powered via USB or with batteries; the infrared sensor is waterproof but cannot be USB-charged and requires three AAA batteries, while the receiver uses two AA batteries. Both units include mounting bases and the sensor offers wide aiming adjustment — 360° horizontal rotation and 180° vertical tilt — for optimal positioning.
