Parktronic 4/6/8 Parking Sensors Kit Reverse Backup Radar System PDC Rear and Front View with Sound Warning Ultrasonic Distance

Please note:► This page offers systems with 4 sensors, 6 sensors, or 8 sensors. Product features and sensor operating logic vary depending on the selected configuration.► For a 4-sensor system, all sensors are installed at the rear of the vehicle. However, on the page, some cars show sensors also at the front — this is actually a feature of 6- or 8-sensor systems.• Product with 4, 6, or 8 Sensors – Operating Modes & Accessories Differ by Model. so please select carefully.•The product list with different quantities of sensors is shown in the figure below.Working Principle of 4/6/8 Sensor SystemsThis system is available with 4, 6, or 8 sensors. The operating logic of the sensors differs depending on the configuration.►4-Sensor SystemEquipped with only four rear sensors (labeled A, B, C, D). There are no sensors at the front of the vehicle.Working scenario: When the vehicle shifts into reverse gear, all four rear sensors (A, B, C, D) are activated.► 6-Sensor SystemEquipped with a total of six sensors: rear A, B, C, D; and front side sensors G, H.When reversing: Activates rear A, B, C, D and front side G, H (all six sensors).When driving or braking: Activates front sensors G and H.►8-Sensor SystemEquipped with a total of eight sensors: rear A, B, C, D; front center E, F; front side G, H.When reversing: Activates rear A, B, C, D and front side G, H (six sensors), while front center E/F go into intelligent standby. When driving or braking: Activates all front sensors (E, F, G, H).The display has 2 values, representing the danger distance in front of the car and behind it! If you choose a product with 4 sensors, you will only get the value behind the car.The display has four adjustable sounds, mute, buzzer, voice, buzzer + voice, when the obstacle is closer, the sound of the alarm will be faster.The alarm volume can be adjusted.The display cable is separated, which is easy to install ►Features:1: High accuracy: Using ultrasonic detection technology, the distance between obstacles and cars can be measured quickly and accurately, and the distance information is transmitted to the display. The driver is warned of possible dangers in advance through images and sounds on the display.2: Intelligent control: Automatically identify obstacles around the vehicle during the reversing process. Help the driver better understand the location and distance of obstacles.3: Easy to use: The reversing radar is easy to install and very convenient to use.4: High reliability: The sensor is usually installed on the rear bumper of the car, and the detection range covers the area around the vehicle, including some blind spot areas that are difficult to observe.5: Strong adaptability: adaptable to various weather and light conditions, and can work normally even at night or in severe weather conditions.6: A very practical auxiliary device, which greatly improves the driver's safety and convenience when reversing.►Specification:Rated voltage: DC 9V~16VDetection range: rear 0.3M~2.3M, front 0.3M~1MRated current: 100mA-300mAUltrasonic frequency: 40KHzControl module operating temperature: -30-80 degrees CelsiusDisplay operating temperature: -20-70 degrees CelsiusInstallation method: 16.5mm drillingSound: heartbeat type, the closer the obstacle is, the faster the alarm will be►High-quality sensorQXNY is a professional manufacturer of automotive parking sensors, and we know better how to produce high-quality sensors that deliver faster and more accurate detection data. ► 4 Sensors Installation Red cable - reversing light+Black cable - negative pole►6/8 Sensors Installation Red cable - ACC+Yellow cable - reversing light+White cable - brake light+Black cable - negative poleSensor Installation Requirements 1: Rear installation height must exceed 50 cm from the ground; front installation height must exceed 45 cm.2: Ensure the sensor surface is perpendicular to the ground.Critical Note: The sensor must not detect the ground.Error 1: Height less than 45 cmError 2: Surface not perpendicular to the groundError 3: Surface tiltedQ1: What should I consider during installation?A ：Sensors Key Installation Points(Purpose: To prevent ultrasound from detecting the ground and generating false alarms)Rear Sensors: >50 cm | Above groundFront Sensors: >45 cm | Above groundSensor surface must be perpendicular to the ground; no tilting allowed.generating false alarms)Q2: Will rain, snow, or mud affect the radar’s performance?A: NO,Sensors are rated IP67 waterproof/dustproof and feature false-alarm filtering algorithms. Wipe sensors clean routinely. Q3: How is the display mounted? Does it glare at night?A:The display is mounted on the dashboard. When braking, if no obstacles are detected, the display remains inactive to avoid visual distraction and ensure driving safety.Q4: How sensitive is the radar detection?A: Many customers misunderstand this: higher sensitivity ≠ better performance. Our radar’s sensitivity is calibrated to a stable, optimized balance through rigorous real-world testing. Q5: How accurate is the object detection?A: Detection accuracy depends on multiple factors, especially the type and shape of obstacles. For example:Moving pedestrians，Fast-approaching vehicles，Thin poles/columns，These objects reflect ultrasonic waves differently due to their size, material, and motion, causing variations in distance calculations. To objectively assess accuracy, we recommend standardized testing using a flat, stationary object (e.g., a wall) under controlled conditions. This eliminates variables and provides consistent benchmark results for reference.Q6: Can it integrate with my car’s backup camera or infotainment screen?A:NOQ7: My car already has rear sensors. Can I add only front sensors?A:Certainly! Feel free to explore our professional front parking radar system – simply search "Front Parking sensors" in our store to view the product.Legal DisclaimerThis product is designed as an parking aid and must be used with caution.
