Features: 1.4 sensor system, double CPU and advanced chipset for enhanced coverage and detection (0.3-2.5m). 2.Advanced chipset for enhanced coverage and detecting. 3.Detect small objects and bars. 4.Enable you to prevent dangerous and costly collisions. 5.Provide increased safety for paengers, pedestrians and family members who happen to be around the moving vehicle. Description: 1.Help to provide increased safety for paengers, pedestrians and family members -who happen to be around the moving vehicle. 2.The system detects whether there is a obstacle through the ultrasonic sensor, indicates the direction and the distance of the obstacle via alarm, avoiding the costly backup collisions. Specifications: Product Name: Car Parking Sensor Product Number: LD01-FM Material: ABS + Electronics Color: Black Control Box Size: 100x60x22mm/3.94x2.36x0.87in Size of Sounds Alert Indicator: 41x16mm/1.61x0.63in Length of cable of Sounds Alert Indicator: 2.5m Rate Voltage: 12V DC Detecting Distance: 0.3-2.5m Ultrasonic Frequency: 40KHz Control Box Working Temperature: -20-70 Due to the principle of radar detection, the following conditions (including but not limited to) may affect the accuracy of detection: 1.Smooth surface slope (probe wave is refracted) 2.Sounds-absorbing cotton objects (probes are absorbed) 3.Spherical body with smooth surface (small reflection area) 4.Similar special objects (probe wave reflection is blocked) 5.In case of heavy rain, probe dirt, damage, wirele electromagnetic interference, etc. will affect the detection results Package Informations: Package Size: 205x125x50mm/8.07x4.92x1.97in Package Weight: 260g/9.17oz General Box Package Package Included: 1 x Main Control Box 1 x Sounds Alert Indicator 4 x Parking Sensors 1 x Power Cable 1 x 22mm Hole Saw 2 x Double Sided Adhesive Pad 1 x User Manual Notes:1. Due to the difference between different monitors, the picture may not reflect the actual color of the item. We guarantee the style is the same as shown in the pictures. 2. Please allow slight dimension difference due to different manual measurement. 3.The distance between the probes can be adjusted according to different models. The recommended installation height of the rear probe is 0.5 to 0.6 meters.
