The passive infrared detector is able to monitor an area up to 100 degrees wide. With the integral mask, the detection area can be narrowed down to 20 degrees or anywhere in between. With the swivel mount, the IR-3000 sensor can be adjusted right to left up to 80 degrees and up and down up to 50 degrees. With three different sensitivity settings, the IR-3000 can detect a person up to 12 feet, 25 feet, or 40 feet away. The sensor can also be set to flash an LED or stay dark when a signal is sent.

The IR-3000 is powered by one 9 volt battery and will have a battery life of about 12 months under normal conditions. There is also a low battery alert to notify you when it is time to replace the battery. The IR-3000 is designed for indoor or light duty outdoor applications under an eave, awning, or other protected location.

The WR-3000 is the receiver for the IRWR-3000 system. The WR-3000 plugs into a standard wall outlet and can be placed on a table or mounted on a wall. When the receiver gets a signal from the transmitter, one of four different tones (Classical, Westminster Chime, Ding Dong, or Whistle) will sound for a few seconds. There is also a volume control, allowing you to set the sound to the desired level.

*Actual range will vary depending on the local terrain.
