Key Specifications/Special Features:

• Universal features, easy to install
• Four ultrasonic sensors detect distance and orientation
• Low illumination, wide angle CCD/CMOS camera
• Camera with adjustable viewing angle
• Distance, orientation and rear image shows on monitor
• The sensors aid detecting potential back obstacles and enable accurate distance measurement to make reversing safe and convenient
• Distance to obstacles is indicated by numeric display, and speaker sound
• Orientation indication
• Good-quality PC + ABS housing
• Auto-detecting and auto-alarming mechanism, a beep indicated when turns to reverse gear
• Acoustic signal increases in frequency when obstacles move closer within 1.50m
• 3-stage progressive buzzer sound to prevent bumping:
  • 1.5 to 1.0m: long interval Bi.Bi.Bi., safe reversing
  • 1.0 to 0.5m: short interval Bi.Bi.Bi, more harsher when closed, slow reversing
