Front Parktronic 4 Parking Sensor Kit Prefix Concealed Built-in Flat Assistant System Not Reversing Backup Radar

Pre-Purchase Notes:1:Installation Height: Sensors must be installed at a height greater than 45cm/18in from the ground.2:Alignment: After installation, sensors must remain parallel to the ground. Tilting is not permitted.3:Control Box Placement: The control box must not be placed inside the car fuse box to avoid interference.4:Color Variation: Slight color differences may exist between sensors.  Car front radar detection systemFeatures:1: Professional car front parking sensors.2: In the cab, you can't see the product. When it is working, you can hear the sound of the alarm! 3: The built-in flat sensor is very nice-looking, just like the original part of the car. Many luxury cars use this type of product Installation diagramWhite-----brake light positiveBlack-----GNDRed ------ ACC+  Two conditions for the operation of front-end radar1: When braking2: When the sensor detects an obstacleWhat is the difference between front radar and rear radar?Difference 1:The professional front radar can still work for about 10 seconds after power failure.For example, the driver activated the front radar at position 1, and when car reached position A, the car's speed was already slow. At this point, the driver will no longer brake, and the power to the radar will be disconnected. However, the product will continue to operate for about 10 seconds to detect and alarm at locations B and C.Difference 2: A professional front-end radar should have a detection range of around 1 meter, as the driver can clearly see obstacles beyond 1 meterAs shown in the following figure: When waiting for a red light, if a useless alarm is generated due to the detection distance being too far, it may sound annoyingProfessional front radar VS rear radarFront radar: When braking, the sensor starts to work. When it detects obstacles, the system starts to alarm; when the brake is released, the main power of the system is disconnected. At this time, the main board capacitor discharges the power, and the sensor continues to scan for 10 seconds and then stops. In order to make the driver turn or change lanes in small places, release the brakes, and get the warning of the parking sensor during the refueling process. Finally, the above two functions, the rear parking sensor does not have this function.Smart startWhen braking, if the obstacles are not activated, the user-friendly design avoids the troubles caused by the endless starting system.Product parameters1>Detection range: 0.3M~1M2>Rate voltage: 12V DC3>Rate operating range: 10.5V - 16V DC4>Rate current: 100mA - 300mA5>Ultrasonic frequency: 40KHz6>Control moudle working temperature: -30 - 80 celcius degree7>Display working temperature: -20 - 70 celcius degree8>Sensor diameter: 16.5mm9>Installation mode: DrillingA:High volumeB:Medium volumeC:Mute
