SOLAR WIRELESS ALARMS: Solar powered, no wiring no need replace battery. The outdoor weather resistant solar beam sensor is powered by built-in rechargeable battery, and the battery will be charged by the built-in solar panel on rainy or cloudy days. These is also a charge jack at the back of the sensor which can be also charged by DC5V-DC12V power adapter or powered by extra solar panels if the sensors will be installed indoor or some darkness areas. .

400 METERS WIRELESS TRANSMISSION RANGE: Both the solar beam sensor and the wireless receiver pick up alarm signals up to 400meters away(actual range will vary depending on the local terrain), it is a great solution even you have a large perimeter or property to monitor. The system adopts advanced wireless transmission technology(FSK+FHSS) to avoid the wireless signal interference from other devices.

60 METERS SENSOR DETECTION RANGE: The solar beam sensors works in pair ( one is transmitter, the other one is receiver ), the infrared detection range of the solar beam sensors up to 60 meters, it means the infrared sensing terminals can be mounted up to 60 meters apart.

LOWER FALSE ALARM RATE: The use of active and multiple infrared beams reduce false alarms from small animals and small objects such as birds and falling leaves; Super infrared penetrating power reduce false alarms form the bad weather such as heavy rain/ fog/ snow; The use of infrared analysis technology reduce false alarms from the other nature light sources interference such as strong sunlight.

FULLY EXPANDBLE SYSTEM&GUARANTEED 3-YEARS WARRANTY- Expandable up to 32 sensors to 1 receiver, and 1 sensor can be added to unlimited receivers for complete coverage of your outdoor/indoor property. 4 volume levels adjustment and 35 optional melodies. Match different melody with different sensors around your property to differentiate where motion is being detected. (Such as the melody for the front door is "doorbell", and for the back yard is " Backyard".)
