Infrared Motion Sensor with Alarm

Stay alerted to any movement around your property with the Infrared Motion Sensor Alarm, a reliable wireless motion alert system featuring infrared detection and a loud wireless chime. This battery-powered duo consists of a transmitter sensor and a receiver chime unit, delivering immediate audio and visual notifications up to 80 metres away in open space—perfect for driveways, garages, entrances, backyards, or any area where you lack direct line of sight. Infrared motion detection accurately senses movement from vehicles or pedestrians within a detection range of over 4 metres, triggering alerts only when something passes in front. Wireless operation with an impressive 80-metre range allows flexible placement of the sensor and receiver for optimal coverage around your property. Long battery life of approximately 2 years using just 6 AA batteries (3 in the transmitter, 3 in the receiver) minimizes maintenance and replacement needs. A low battery indicator (blue light on the receiver) provides clear warning when voltage drops below 3.3V. Easy, cable-free installation lets you mount the transmitter sensor outdoors (on walls or gate posts) and place the receiver indoors wherever you need to hear the alert—no drilling or electrical work required.
