24GHZ Radar Blind Spot Detection Ultrasonic Sensor Kit Rear Cross Traffic Alert System for Car Item Type: Blind Spot Detection Material: ABS System Solution: German microwave probe Detection Range Accuracy: Approx. 0.1m/4.0in Maximum Detection Range: Approx. 10M/32.8ft Warning Range: Approx. 3 - 10m/9.8 - 32.8ft System Warning Accuracy: Approx. 0.1m/4.0in Warning Mode: Sound and light warning Waterproof Rating: IP67 Warning Time: Minimum warning response time 0.75s Operating Frequency: 24GHz - 24.25GHz Working Temperature: -45℃ - 85℃ Storage Temperature: -45℃ - 85℃ Application: Universal Installation Instructions 1. Remove the rear bumper and determine the installation position of the radar bracket. The two radar heads are respectively installed in the left and right corner parts of the rear end of the car body, inside the bumper. 2. Fix the left and right radar systems on the bracket respectively, and then bolt them together with the bracket. 3. Radar installation requirements: The radar needs to be placed horizontally, and the height and angle of the left and right information acquisition system should be adjusted; The radar must be placed horizontally, not tilted, and the ground clearance is higher than approx. 55cm/21.7in The launching surface forms a vertical angle with the ground: the premise that the radar must be parallel to the contact surface; The angle between the launching surface and the horizontal line of the rear of the vehicle body: the left and right sides are inclined outward by 25°, forming an splayed shape; the angle ruler touches the radar surface and the arrow is parallel to the longitudinal direction of the vehicle body (the vehicle needs to stop straight, and the wheels keep the same direction); The radar sensor (signal emitting surface) can only penetrate the plastic bumper shell; There should be no metal (such as wiring harness, reversing radar probe) interference directly in front of the radar sensor (signal transmitting surface); The wiring harness that connects the radar probe and other wiring harnesses should be straightened and tightened, and fixed tightly every approx. 20cm/7.9in with wire clips and cable ties to avoid interference. 4. Main control box installation Find a suitable location in the trunk (different vehicles, the site shall prevail), you need to pay attention to the following factors: It is convenient to fix the position and wire harness wiring to ensure that the length of the wire harness is sufficient Easy to connect ACC power cord Keep away from batteries, high-current wiring harnesses and audio amplifiers 5. Wireless receiving slave and lens installation A. Need to remove the front left and right door panels B. Need to remove the rearview mirror assembly C. Replace the lens with blind spot lights, with left and right turn signal lines at the lamp line (left is pink, right is purple) D. Wirelessly receive the wiring between the left and right slaves and the lens E. Wireless receiver installation Find a fixed installation surface on the left and right door panels according to the size of the receiver Find an available power supply on the door panel. The positive pole of the wireless receiver power supply is connected to ACC and the negative pole is grounded. F. Door rearview mirror assembly restoration
