## Description

Product description The car is convenient for our lives, but it is also a very dangerous tool that can easily become dangerous if you are not careful when driving. What a great reminder it is to have a sound to alert us when there are children or obstacles next to the car. Scene display ELSNY, an excellent brand of reversing radar, alerts the driver when the car is reversing in 3 ways: sound, digital and light bar. The car reversing radar system is composed of 4 ultrasonic sensors, a digital control box and an LCD display, making it easier to park any vehicle. It automatically detects the distance between the car and the obstacle behind it through a sensor installed on the rear bumper of the car. It helps avoid dangerous and costly collisions that can easily happen behind the steering wheel Monitor When the car is reversing, the 4 sensors start working and the display shows the distance and orientation information of the nearest obstacle detected by the sensors. The driver is alerted by sound, light bars and numbers. Sound switching With the button you can switch between three alarm sounds, voice, beep or mute. Tip. If you are an experienced driver and reverse quickly, choose beep. If you are a new driver and reverse slowly, choosing the voice alert is more suitable. If you are reversing too fast, the voice alert may not be able to keep up with your reversing speed. Parameters sensor detection range: 0.3M~1.2M Rated Voltage: 12V DC Rated Current: 100mA - 300mA Ultrasonic Frequency: 40KHz Operating temperature of control module: -30 - 80 degrees Celsius Display operating temperature: -20 - 70 degrees Celsius parking sensors We have been specialising in manufacturing reversing radar for 12 years, so we know more about how to make quality sensors. We use dual angle, 22MM openings with large chip sensors to ensure more stable performance and more accurate data detection. ( You can paint the sensor to change the colour of the sensor ） Protective box We have upgraded the box of the controller so that every wire harness connected to the box can be tightly secured without loosening or making poor contact due to the shaking of the car. Note The display has a protective film that can be peeled off when in use. Note when mounting the sensor: 1: Do not squeeze the middle of the sensor, 2: The mounting height is approximately 18 INCH from the ground, 3: The sensor needs to be kept parallel to the ground. Control box, not to be placed in the car fuse box, where there will be electromagnetic interference Notes Sensor Installation Right 1: The mounting height is approximately 18 INCH from the ground, 2: The sensor needs to be kept parallel to the ground. Error The sensor tilts towards the ground, generating a false alarm. The distance between the sensor and the ground is too small, generating false alarms. Sensor tilted towards the sky, no effect

I installed it on my front bumper and it works , i connected it on my running light.

### ⭐ Not worth it.
*by A***O on January 18, 2026*

This seemed like a good buy until I had it installed. It often given inaccurate notifications about distances from objects. Sometimes it sounds a warning even when there is no object nearby. Wouldn't buy this again.
