Greencycle IP65 Outdoor Motion Sensor Alarm — Waterproof Mailbox/Door Anti-Theft Detector with 900FT Long-Range Ringer, for Vehicle/Garage Entry, 1Receiver+3Sensors

Compact, weatherproof motion alarm system from Greencycle designed for outdoor perimeter alerts. The IP65-rated sensors incorporate four independent LED zones so you can tell which sensing area was triggered; you can also sync audible alerts across zones. In addition to sound, the unit offers a new silent yet powerful vibration reminder for discreet notifications. Using composite infrared + microwave radar detection, the unit reduces false alarms and lets you disable the probe light for low-profile monitoring. The detector itself features a three-layer waterproof design and a software de-interference algorithm to further cut down on spurious triggers. Detection performance: sensing distance 2-8 meters, radar range 6-8 meters (depending on temperature). The wireless link between sensors and receiver reaches up to 918ft (280m) in open areas. Ideal for monitoring driveways, porches, gates, homes, sheds, offices, walkways, swimming pools, stores and similar outdoor areas — the system provides an extra layer of security around your property. Flexible and expandable: mix and match transmitters and receivers to suit your setup; assign different lights or ringtones to each unit. Each receiver supports up to 32 motion sensors and 8 remotes for broad coverage. Installation is straightforward: the receiver can be powered by USB or batteries, while the infrared sensor is waterproof but cannot be USB-charged (requires three AAA batteries). The receiver needs two AA batteries to operate. Both sensor and receiver include mounting bases, and the infrared sensor offers 360 degrees horizontal rotation and 180 degrees vertical tilt for optimal placement.
