This product is a replacement outside round light with battery and motion sensor capabilities. Fixture can be a regular porch light or a motion sensor light with a flick of the switch. It can also differentiate between animals and people to reduce false detection at night. Photo sensor allows the unit to be fully automated, turning itself off during the day, and on at night when proper motion is detected. Battery sensor triggers a red LED on the fixture when battery levels reach 11.5 volts for 40 seconds.
