Acuity Brands Lighting - NCM PDT 10 RJB - Low Voltage Ceiling Mount Sensor, Passive Dual Technology, Large Motion/Extended Range 360deg Lens, Rear RJ-45 Ports, SKU - 230CEP

| SUPERIOR THAN PIR | Our microwave sensor emits microwave signals to detect moving object, the same way a radar speed detector works. It is more accurate and consistently outperforms a PIR motion sensor, which tends to be less sensitive in high temperature and over sensitive in low temperature..
| BETTER DETECTION | Features 360-degree detection with 30-ft diameter detection range. Radar waves are capable of penetrating glass, paper, plastic and thin walls. Compared with a PIR motion sensor, a radar motion detector is less likely to be limited by place of installation and could detect objects before they see the sensor..
| PHOTOCELL ENABLED | With built in photocell operated by switch for daylight (24/7 mode) or night mode (only trigger after dark), making the sensor a perfect replacement of PIR sensors..
| SAFE TO USE | This sensor emits microwave power at 10 milliwatt, which is 1/100 of a normal cell phone (typically 1-2 watts of power). Suggested install height is 8-12 ft., compared to a cellphone which is normally used within 3 ft. You can use this radar motion detector safely and with peace of mind..
