Extra solar wireless radar sensor compatible with original driveway alarm by htzsafe. Lower false alarm rate-the use of radar wave to reduce false alarms from small animals and small objects such as birds and falling leaves; and the bad weather such as rain/fog/snow; and the other nature light sources interference such as sunlight and etc. Wide range of application(driveway, perimeter defense and etc)- the wireless range from the sensor to the base receiver is up to 1/4 mile(actual range will vary depending on the local terrain); the sensor detection range is up to 50 feet(actual range will vary depending on the size of the movements; if cars, the detection range is about 50 feet; if a person weighting 50kg, the detection range is about 20 feet).

Solar powred no need replace batteries- the sensor is powered by built-in rechargeable lithium ion battery which will be charged by the solar panel, so no need replace the battery, save your time and money. (the sensor also can be powered by the dc5v-12v power adapter if you do not want to use the included solar panel). Diy design, super easy to set up in minutes-the sensor is solar powered and no need replace batteries; wireless communication between the sensor and the alarm receiver, so the installation time can be as little as a few minutes.

Long range connection – motion sensors connect with receiver from up to 350 feet away in open space.

Passive detection – passive infrared (pir) technology continuously monitors motion within 25 feet of sensor.

Easy to set up- the solar sensor is equipped with self-calibration tools (calibration hole), capable of finishing long range calibration in minutes. 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 from the bad weather such as rain/fog/snow; infrared analysis technology reduce false alarms from the other nature light sources interference such as sunshine. Extra solar sensor compatible with original drivway alarm by htzsafe. No wiring no need to replace batteries- self-powered by solar recharged lithium ion batteries; no need sunshine, the nature light on cloudy and rainy days also can charge the batteries normally; requires no wiring(both the power cables and signal cables).

Wide range of application(driveway, perimeter defense and etc)- the infrared detection range of the solar sensors up to 190 feet, that means the infrared sensing terminals can be mounted up to 190 feet apart; and will send a wireless alarm signal back to the solar receiver up to 1/4 mile away anytime someone passes between the solar sensors(actual range will vary depending on the local terrain).
