• Mount the detector properly by the front door, window frame, driveway, walking path, backyard, or anywhere you need.
• Easy, Fast, Wire Free Installation: Infrared sensor detects motion and sends a signal to the receiver. Choose from 38 ringtones with bright LED light. Sensor is wall mountable.
• The portable wireless plug-in receiver plugs into any standard outlet. The sensor uses 3 AAA batteries (Not Included).
• Music: 38 music options. Third-level volume adjustment (high, medium, low) Side volume buttons to adjust. Can be set to sound and silence (voice: sound + light, sound: light).
• Note: The sensor should be installed at a height of about 2 meters; the lateral detection of the sensor is more sensitive than the straight line (the human body directly faces the sensor), and it should generally be installed on the side or top of the entrance door and adjusted to the appropriate position through the mounting bracket so that it can achieve the best induction.
